The Deep is an aquarium along the marina in Hull, and is one of the most impressive buildings on the Hull skyline; the main building is built to resemble the keel of a giant ship, with a glass viewing window overlooking the River Humber. The display starts near the top of the building, which you reach either via a lift or a very long set of stairs.

The first animal display in the Deep is 'Visions of the Ocean', a single small tank that comes up straight after the entrance turnstiles. This aquarium houses a variety of smaller reef creatures, including a shoal of bangaii cardinals, razorfish, an unidentified pufferfish and a red-knobbed starfish.

Following on from this are mostly interpretative displays, starting with an introductory short film display with a commentary about the oceans. Then, there is a large interactive map showing the geography of the oceans, such as the deepest points. Then there is the 'Evolution of the Oceans' display- this has a fossil wall showing a timeline of the oceans featuring creatures such as mosasaurs, dunkleosteus, xiphacantis, anomalocaris and zygorhiza as well as individual feature displays for species such as icthyosaurus, archelon and megaladon. A display that normally houses moon jellyfish was empty for maintenance. The final section of the 'Evolution of the Oceans' is a pair of displays based on a mangrove swamp. The first has a model of a Tiktaalik, a prehistoric fish/amphibian that left the water to feed. The other larger display has fake mangrove trees and a large number of West African mudskippers, which have also adopted the terrestrial and aquatic lifestyle once employed by Tiktaalik.

The next area is the 'Lagoon of Light' and 'Coral Realm' which are in fact both the same enclosure. The first section visitors encounter, the lagoon of light is much shallower and lighter, with more open areas than the coral realm. This is the main collection of tropical reef fish, housing species including bicolor parrotfish, regal tang, yellow tang, achilles tang, harlequin tuskfish, emperor angelfish, striped surgeonfish, bicolor angelfish, cleaner wrasse, whitetail damselfish, foxface, long-horned cowfish, a large species of hermit crab, bluespotted ribbontail ray, epaulette shark and brownbanded bamboo shark. Also in this section is a smaller tank housing maroon clownfish, purple tang and further yellow tang. The walkway then curves round and shows visitors into the coral realm, a far deeper section where the reef fish can also explore.

The next area is the 'Endless Ocean', based upon a tropical open ocean that houses numerous species that all live together in a huge tank that is over ten metres deep. This tank can be viewed from several different areas, including from inside a cave. The species living in here that were present on my visit included white-tipped reef, grey reef, nurse and zebra shark, green sawfish, Southern stingray, leopard whipray, humphead wrasse, horse-eye jack, lookdown, black-spotted sweetlips, golden trevally, blue-striped snapper, green moray eel and cleaner wrasse. This is one of my favourite single displays in any aquarium collections I have visited before.

What was originally to be a temporary display but now is seemingly permanent, is 'Slime!' This small area houses species that rely upon slime for their survivial, and the species present in here are: common clownfish, sea apple, spotted garden eel, East African giant land snail, tiger slug, Eschmeyer's scorpionfish, green-and-black poison-dart frogs and a single blue poison-dart frog.

Since my last visit, the next main display has changed. A large open area has become a 3D cinema about sharks, and a display known as 'Northern Seas' that housed local British species has now become a permanent Amazon display that houses red-tailed, tiger shovelnose and jigsaw catfish, silver arowana, black pacu, motoro stingray and two species of freshwater turtle (I only saw a single Geoffroy's side-necked turtle, but apparently there is also a pair of yellow-spotted Amazon turtles). This tank is open and roomy, and allows for plenty of space for the fish to swim.

The 'Twilight Zone' has changed significantly since my previous visit, with many species having left or gone off display. Upon entering there is a short film that I chose to skip, and then you enter a large room where the tanks are mostly darkened to allow visitors to see the animals more active. The first tank houses emperor nautilus, the next which normally houses North Pacific giant octopus and Pacific sun stars was empty and the third holds Norway lobster, spot shrimp and longspine snipefish. Then there is a series of tanks for moon jellyfish, and opposite this is a larger tank holding the former denizens of the 'Northern Seas'. These include pollack, Atlantic cod, ballan wrasse, cuckoo wrasse, bullhuss and thick-lipped grey mullet, along with the spotted ratfish that formerly inhabited this tank. The next aquarium has strips of cloth covering it, and you have to stick your head behind it to see the species in here. In the near-total darkness live splitfin flashlightfish and pineconefish. The next tank houses a common lobster and the final aquarium is home to fish-eating anenome, Pacific sun stars, rockfish and wolf-eels. On leaving here, you reach the area you started at, and can have the chance to visit the cafe and have a meal or a drink before continuing.

'Ice World' is the smallest of the zones, being made up by a single corridor and only one aquarium that houses a swarm of glass shrimp. These crustaceans show the importance that both they and the similar krill have in the polar oceans. An interesting part of this display are the 'ice walls' that are both literally made of ice- these also have films beamed onto them of polar species like penguins and leopard seals.

A play area follows, but fortunately it is hidden away and not very obtrusive, and visitors can head down to the final area, known as 'Deep Blue 1'. This is a research area, and formerly housed interactive games about the oceans but now has been renovated into a fantastic series of enclosures based upon the world's rivers. They all house smaller species from river areas from places as diverse as the Amazon, the Mekong and water bodies from Mexico and southern Arizona. The species living here are as follows: leaf-cutting ant, emerald tree boa, blue poison-dart frog, Surinam toad, South American giant fishing spider, red-bellied piranha, Amazon milk frog, sunburst diving beetle, axolotl, Potosi pupfish as well as two currently empty aquariums awaiting new residents. This area then goes into an underwater viewing tunnel at the bottom of the Endless Ocean tank, extends around to a final area based upon the park's conservation programmes and also houses an aquarium for upside-down jellyfish before finally allowing visitors to choose to either go up in a lift or flights of stairs, both with the opportunity to look into the Endless Oceans tank.

The gift shop (known as the Deepartment Store) also has a couple of aquaria. The first is a circular kelp forest aquarium with sea urchins, anenomes, shiner perch and painted greenling while the other is a large Amazon aquarium housing smaller freshwater species, namely cardinal tetra, angelfish, two species of South American cihlid, silver hatchetfish and marbled hatchetfish.

Since my previous visit, many interesting species have either gone off display or left the collection. These include the bonnethead sharks, sand tiger sharks, Pacific hagfish, North Pacific giant octopus, bird wrasse, Japanese giant spider crab, giant isopod and there is no sign of the spotted wobbegong or lion's mane jellyfish either.

All inall, this is my favourite aquarium I have visited with a great diversity of species, brilliant education facilities (having enormous indoor research areas used by the local university), excellent signage and great interactive facilities. On my visit, my personal favourite species were the spotted garden eels, sunburst diving beetles, green sawfish, emerald tree boa and South American fishing spiders.

Thank you DesertRhino, it's been a few years since I visited The Deep so I must go again soon. I think it ranks with the National Marine Aquarium at Plymouth as the best in England.

I went here last year and loved it, definitely the best aquarium I've been to, the main tank really impressed me, the viewing windows are very spacious and give you some great views. The moon jellyfish tank at the beginning was empty when I went last year, pretty long time for maintenance! Overall its a lovely experience, I'm glad the interactive zone has gone and been replaced, it did seem a little pointless and space that could be used better. I'd happily return here for another visit.

Sorry to hear so many species have gone - I'll miss the hagfish (the only ones I've seen) and isopods particularly. Do they still have rabbitfish/chimaeras in the Twiligiht Zone area?

Departures notwithstanding, The Deep is by far my favourite UK aquarium (of the ones I've visited; I still need to get to the National Marine Aquarium, about which I've heard good things).

There were at least three spotted ratfish (Hydrolagus colliei) in their tank, just mixed with the British fish and no spider crabs. I think they are the same as rabbitfish/chimaera.

Yes, they're the ones! One of those awkward groups with more common names than necessary. :D

Good to hear they're still there - thanks for confirming.

They're a completely separate class (Holocephali) from any other fishes - last time I went to The Deep they were one of two* new classes of animal I saw that day. New species and genera crop up fairly regularly but new classes are something really special.

I think it's a real tribute to your enthusiasm to get excited over hagfish. I will admit to no more than gentle curiosity, mixed with a frisson of disgust ;). But I didn't do a double because I'd seen chimaeras before at Blackpool Sea Life Centre (I don't know if they still have them).

I got very excited at both the hagfish and the chimaeras. It was a good day. :D

Not sure when you saw chimaeras at Blackpool but they weren't there in March 2010.
 
I managed to sneak in another brief visit on Friday while up in Hull, and there have been some minor developments there:

- The new 'Explorer's Den' has opened- it is a tiny display featuring a live link webcam to a bird table in the Brazilian rainforest, a small tank featuring bladderworts and monkey cup plants and several displays of rainforest invertebrates (which I missed)
- I found I have made an error in my previous review- in the Amazon tank there are ripsaw catfish (Oxydoras niger) instead of the completely fictitious jigsaw catfish I originally labelled.
- Managed to see individuals of both the Geoffroy's side-necked and yellow-spotted river turtles.
- The old Pacific giant octopus aquarium has been renovated and now houses spiny spider crabs (Maja squinado)
- White-spotted jellyfish (Phyllorhiza punctata) are now displayed in the Twilight Zone along with the moon jellyfish.
- The rivers exhibition now has three rivers represented (the Amazon, Rio Grande and Mekong) with the milk frogs from the Amazon area no longer on display and the two Mekong tanks holding bumblebee gobies and green-spotted puffers in one and mosquito rasboras in the other.
- Also some new tanks were being installed in the rivers exhibition, presumably for the Congo and Betsiboka rivers indicated on the various signage- looking forward to seeing some new and hopefully exciting species for these displays!
 
Managed another visit yesterday, and got to see quite a few of the changes to the aquarium:

- No more brown-banded bamboosharks in the Lagoon of Light exhibit
- The green-and-black poison-dart frogs at Slime have been replaced by at least ten blue poison-dart frogs
- There was no sign of any turtles in the Amazon tank; hopefully they are just off-show
- The giant octopus aquarium has become home to a pair of European spiny lobsters
- The 'Bug Champions' exhibit is around the Amazon tank, entrance to the Ice World and by the cave viewing area to the ocean aquarium, and features nine species in three categories: Largest (bull's-head cockroach, Macleay's spectre stick insect and mega mantis, which was off-show), Stongest (black beauty stick insect, giant spiny stick insect and blue death-feigning beetle) and Fiercest (mombo or red-spotted assassin bug, greenbottle blue tarantula and giant vinegaroon). The enclosures are all well designed and generally allow good views of the inhabitants.
- The Deep Blue 1 rivers exhibit is now perhaps my favourite part of the aquarium, with five different rivers represented. The exhibits house, in order:
Amazon- leaf-cutting ant, Amazon tree boa, green-and-black poison-dart frog, Surinam toad, South American giant fishing spider, red-bellied piranha and Amazon milk frog
Rio Grande- sunburst diving beetle, Potosi pupfish and axolotl
Mekong- green-spotted pufferfish and mosquito rasbora
Betsiboka- Madagascan hissing cockroach, golden mantella and pinstripe damba
Congo- sun beetle, Tanzanian red-legged millipede, emperor scorpion and mixed African knife fish, freshwater butterflyfish and reedfish
 
I managed a trip to The Deep yesterday - the first visit since the above trip in 2012. A lot has changed since then. I will mention new things that I remember, as I didn't take detailed notes and am mostly working off memory:

1) Visions of the Ocean
The first tank, just behind the turnstiles, is home to a small variety of fish - on my trip around, I saw a shoal of banded shrimpfish and a copperhead butterflyfish, with the signed kuda seahorses not visible.

2) Evolution of the Oceans
The fossil wall and models of extinct marine creatures have remained the same. The jellyfish tank halfway down the walkway has been changed and now houses tube anemones and several species of shrimp.

The Tiktaalik tank has remained unchanged, while the tank that formerly housed Atlantic mudskippers is now home to upside-down jellyfish.

3) Lagoon of Light and Coral Realm
This combined display, with the Lagoon of Light being a shallow lagoon display and the Coral Realm being a deeper part of the same tank, has had some cosmetic changes since my last visit. In 2017, the tank was re-themed to resemble a coral reef bordering a mangrove forest in Palau - to get an idea of what the display now looks like, the exhibit designer has included images here.

There are plenty of fish here, although I did not make a comprehensive note of all the different species. Species I saw that I could identify include the yellow tang, pyramid butterflyfish, Picasso triggerfish, porkfish, bluestreak cleaner wrasse, bluespotted ribbontail ray and bluespotted maskray. I did not see the signed epaulette sharks, but there was a whitespotted bamboo shark swimming around in the tank. There are also huge numbers of golden damselfish in here, which are possibly the most common species in this display.

The touch tank area in the corner next to Lagoon of Light seemed to be empty, although I did not really stop to look.

The smaller separate tank midway down the walkway between Lagoon of Light and Coral Realm was originally home to just a small handful of species. Now, it has a much wider variety of small fish, including azure damselfish, sea goldie and orchid dottyback (again, I did not note the full species list).

There is another new section between these two exhibits and the next one, but that will be expanded upon more in part 7.

4) Endless Ocean
This is the largest tank in the aquarium, and can be viewed from five different storeys. New species that have arrived since my last visit include a lace moray and the pair of loggerhead sea turtles. The other species in here include the pair of green sawfish, grey reef and whitetip reef sharks, zebra sharks, nurse sharks, black and honeycomb stingrays, giant moray eel, golden trevally and bluestreak cleaner wrasse. There are no longer any other bony fish in the tank, such as the jacks.

5) Slime!
This exhibit has been halved in size - the left side has remained, with the right side now changed into the Changing Seas exhibit (see number 6). This means the tanks for sea apple and Eschmeyer's scorpionfish have been removed. The three tanks are home to a mix of ocellaris clownfish and sea anemones, a mix of spotted garden eels and scribbled pipefish and a tank for blue poison-dart frogs.

6) Changing Seas
This is the newest section, and has replaced half of the Slime! display. It is a single long tank, home to a range of fairly standard reef fish - it seems that the original theme of toxic species such as lionfish and pufferfish has been done away with, as neither of these species were present. There is still a lot of information about the influence of climate change on the oceans around this tank.

7) Amazon Forest
This tank is themed on a flooded forest, and is designed partly to link to the aquarium's work with the Big Fish Project, showcasing just how big some widely-available aquarium fish can grow and so encourage people not to but them for a home aquarium (such as pacu, red-tailed catfish and tiger shovelnose catfish). I think it may also have provided a home for rescued fish that had outgrown their previous homes.

It could be that this tank is now a victim of its own success, as on my visit the huge tank now seemed to be home to just a pair of black pacu, which despite being big do very little to fill the space.

I should also note that the big open area in front of this tank, which in the past featured the Bug Champions and Hull Bugs exhibits, is now empty of animal enclosures.

8) Cool Seas
This area has had some of the biggest changes since my last visit. When I last went, it had a broad theme combining species from northern climes and from the deep sea. Now, it has focused almost entirely on native marine life. The little circular room that introduced the section now has a series of tanks for jellyfish - the species on-show when I went included the Australian white-spotted jellyfish, Japanese sea nettles (two tanks) and moon jellyfish (one tank for adults and a row of tanks showing the jellyfish life cycle).

The three three tanks originally housed nautilus, giant Pacific octopus and a mix of snipefish, spot prawns and Norway lobsters. Now, the nautilus tank houses native oysters, the octopus tank is a seagrass aquarium that includes pipefish and fifteen-spine sticklebacks and the mixed tank is home to limpets.

The area where the jellyfish tanks was has been changed to a tide pool based on Flamborough Head. Periodically, a large wave sweeps over the pool, which is home to seaweeds, native sea urchins and several fish including a scorpionfish.

The big marine tank is now entirely for native marine fish such as pollock, haddock and both cuckoo and ballan wrasse. The spotted ratfish are no longer present.

The two tanks that originally housed flashlightfish and pineconefish and European lobsters have also been changed - the dark tank is now home to a mix of at least five species of native sea star and the lobster tank is now home to snakelocks anemones and dead-man's fingers.

The last tank is still home to the ocellated wolf-eel, but the theme has been changed to a kelp forest and is also home to sea stars.

9) Ice World and Penguins
The first bit of this section you see is an above-water view of the penguins, between the Lagoon of Light and Coral Realm viewing areas. This enclosure is almost entirely indoors, although I think it does include off-show access to an outdoor balcony in appropriate weather, and is home to a breeding group of gentoo penguins.

Of the two all-indoor penguin exhibits I have seen (the other being at the London Sealife), this is better by pretty much every category. The exhibit is based upon the abandoned settlement of Grytviken in South Georgia, and is themed with a jetty and whale bones to show its status as a former whaling station. There is also a lot of information about Hull's links to Antarctic exploration, including Ernest Shackleton's Endurance expedition.

The Ice Tunnel still exists, although the one tank no longer houses living animals. Instead of glass shrimp, it is now a display of floating plastic waste to show the problems caused by plastic to marine life.

At the end of this tunnel is both the underwater view of the penguins and a view into a lower land area, where several of the penguins could be seen sat on eggs. There was a lot of signage about the different species of penguin, the life-cycle of a penguin, a board where all the individual penguins on display could be identified by the colour bands they wear on their flippers and information about the breeding of penguins at The Deep. While I was walking past, a keeper was doing a talk and explaining that only one pair of gentoos in the exhibit is allowed to breed, as they are the only pure Pygoscelis papua ellsworthi in the colony.

10) Deep Blue One
This was my favourite section on my previous visit, and I think it remains so. Its freshwater theme allows for a collection of small and fairly choice species. The section continues to showcase the same five rivers as before, although some of the species are now out of place. The five rivers, and each of the tanks within these sections, are:

Amazon
  • Cat-eyed mantis (tank formerly for more appropriate leaf-cutting ants)
  • Amazon tree boa
  • Green-and-black poison-dart frog
  • Dwarf Surinam toad, Pipa parva (formerly for Pipa pipa)
  • Empty (unsigned, on previous visit home to giant fishing spider)
  • Empty (still signed for red-bellied piranha)
  • Amazon milk frog
Rio Grande
  • Sunburst diving beetle
  • Lake Zacapu garer snake (on previous visit home to Potosi pupfish)
  • Axolotl
Mekong
  • Empty (still signed for figure-of-eight pufferfish)
  • Red devil vampire crab (tank not occupied on my previous visit)
  • Butterfly splitfin (a Mexican species) and unsigned mosquito rasbora
Betsiboka
  • Madagascar hissing cockroach
  • Green mantella (on previous visit home to golden mantella)
  • Madagascar red killifish (on previous visit home to pinstripe damba)
Congo
  • Turquoise dwarf gecko (on previous visit three tanks for sun beetles, millipedes and scorpions)
  • African knifefish and a leopard bushfish (on previous visit the knifefish shared with freshwater butterflyfish and reedfish)
11) Deepartment Store
The shop continues to have two different aquaria within it - one a large cylindrical kelp forest tank within the store itself; the species I saw in there on my visit were shiner perch, bat stars and fish-eating anemones.

The other tank is beyond the tills, and is the last exhibit you see before you leave. While before it was home to a mix of smaller South American freshwater fish, it was now home to at least three adult yellow-spotted Amazon river turtles and a red gibbiceps catfish.

The entrance ticket remains valid for an entire year, so maybe I will be tempted to take the train back up there in the near-future for a more thorough visit. It is certainly still my favourite aquarium that I have visited, and holds up very well compared to other aquaria I have revisited after a long break (thinking of the London Sealife particularly here).
