Point Defiance Zoo & Aquarium Point Defiance Zoo & Aquarium

How many musk ox does the zoo have now?
4 total, Hudson & Charlotte (adults), then Willow (their calf) and now Pretzel.

Should be noted that the Zoo responded to someone on FB and mentioned that Hudson won't be breeding anymore. They didn't say anything about Charlotte but it sounds like the pair will be retired from breeding purposes since all 4 are planned to be housed together in the near future.
 
Well, in some absolutely devastating and surprising news, the Zoo announced they've humanely euthanized their last Scalloped Hammerhead due to a sharp decline in health.
They don't mention what happened to the other 2, I'll have to ask someone when I visit soon, but man this is so heart breaking. One of my favorite species for sure.
They were eventually going to outgrow the tank and I was hoping theyd join the existing trio of females at Monterey Bay.

The Zoo also says they will not be bringing in more Hammerheads. I'm guessing half is because when they were pups, they were collected from Hawaii (who's banned the commercial export of marine life besides a few select species) and maybe the maintenance was too much.
Maybe in the future another species of Shark will be brought in.
Point Defiance Zoo & Aquarium on Instagram: "Today, we made the difficult decision to humanely euthanize our last hammerhead shark after a significant decline in her health. She was an incredible ambassador for her species, inspiring our guests to learn about the vital role hammerheads play in maintaining healthy oceans and to take action to protect sharks and marine life. While we won’t be bringing more hammerhead sharks to Point Defiance Zoo & Aquarium, our Baja Bay habitat remains home to spotted eagle rays, green sea turtles, and many tropical fish. Our other sharks – eight species, including blacktip reef and zebra sharks – are healthy and thriving."
 
Minor news but one aquarist mentioned that the zoo currently only has 1 Japanese Spider Crab left in the collection. Apparently one had passed away about a month ago, no mention on what happened to the other 2 (they use to have 4 iirc). I'd imagine the Zoo won't be phasing the species out since they're one of the more interesting species in the Pacific Seas Aquarium + the couple other species of deepwater Japanese fish that are in the tank.
I wouldn't be surprised to potentially see a few more, smaller Japanese Spider Crabs join soon but I have no idea when that'd happen.

Hopefully we get some better news from the Aquarium side soon since the last couple updates have been pretty depressing.
 
Stopped by today since we got a decent amount of snow last night and figured it'd be dead (it was), but some updates:

- The Zoo has put up signage by Suki's old exhibit that says they're still early in the planning stages of what to do with the exhibit but are actively weighing their options on what species will be moving in next.
- Underwater viewing for the Walrus is still closed off (it seems like they could be experimenting with small viewing times since I did see a post the other day of the underwater viewing being open)
- There are now 2 juvenile Panther Groupers, a Koran Angelfish, and a juvenile Orbicular Batfish now in the Lagoon exhibit in the Tropical Reef Aquarium

'Coral Reef Close-up' is still scheduled to open in Spring of this year, because I was the only person in the entire aquarium I was able to overhear a conversation between the aquarists and see a sneak peek of the main tank.
  • The largest tank will be made up of mostly Stony Corals (Acropora, Montipora, Seriatopora, etc your typical SPS corals)
  • The smaller cube tank to the right is entirely up to the aquarists on what they want to do with it. It sounded like they're leaning towards making it a Seagrass tank with Banggai Cardinalfish and Shrimpfish (since they moved the Shrimpfish / Razorfish out of the touch pool area). But a couple ideas they floated were Seahoreses, Frogfish, Cuttlefish, etc.
  • I believe I heard the smaller cube tank to the left will be for Clownfish and Anemones.

Nurse Sharks moving Aquariums, now in 'Baja Bay' exhibit

The Zoo announced that they're in the process of moving their 4 Nurse Sharks (Ginglymostoma cirratum) from the 'Outer Reef' exhibit in the Tropical Reef Aquarium, to the 'Baja Bay' exhibit in the Pacific Seas Aquariums. Their reasons are that some of the new species added to the 'Outer Reef' were having a hard time going through their routines with the Nurse Sharks in the tank. Plus the Baja Bay tank is larger in size so it gives them more room, especially since they'll be the only benthic species in there. Two of them have already moved, with the other two moving soon.

My two cents: I'm a little sad for nostalgic reasons to see them move since they were such an iconic and long standing species of the 'Outer Reef' (especially since they're the original 4 who've been at the Zoo since the 70's), but this is an all around great move for both exhibits. While nothing will ever top the Scalloped Hammerheads, there weren't many species options that could've fit thematically for the tank so this was a good move. Pacific Nurse Sharks (Ginglymostoma unami) are found off the coast of Baja and Mexico, the Zoo's are the Atlantic species so they're acting as a stand-in which is understandable (which they do mention in the article) since i believe "Gran Acuario Mazatlán" in Mexico is the only Aquarium to exhibit the Pacific species.

Since they're the only benthic species, they won't be competing with anyone else for space on the floor. They were by far the largest species in the "Outer Reef" and took up a lot of floor space from other partially benthic species. A few species who I know who have been off exhibit for a while because they couldn't handle the disruption from the Nurse Sharks are the Napolean Wrasse and Black Blotch Ray (via someone i know who is an aquarist at the Zoo). Possibly the Wobbegong too and the Whipray (who hasn't been on exhibit once since opening). Hopefully we'll see these species move back in soon since I'd really like to get a glimpse of the Wobbegong.
(@Local_Shark we might finally see the adult Whipray they say is "H. australis" and get a proper ID :) )

It could also possibly mean they're making room for a few more Sharks the Zoo has talked about bringing in (no species have been mentioned, just that they are planning on bringing in more sharks). I'm very excited by this, the Aquarium's needed a shake up and this is certainly a big one

Wow, this is a BIG change. I am certainly alright with them as a stand-in for G. unami - even Gran Acuario Mazatlán itself actually has a mix of both species despite its Baja location, as some were presumably wild caught locally while others were imported. I’d love to see them signed as such, that would be really nice (and I’m hoping Mazatlán will do the same, after their education staff and I confirmed the species IDs there). And I’d love to get a better look at that whipray and at the wobbegong, so that’s a win as well. Very interested to see what other new sharks might appear across both aquariums too! Thanks for the heads up NWFK.

I can't even think of what they could bring in species wise. For the 'Outer Reef' the new list should look like:
  • 5 Black-tip Reef Sharks
  • 3 Grey Reef Sharks
  • 3 Zebra Sharks
  • 2 White-tip Reef Sharks
  • 1 Tasseled Wobbegong
  • 1 Black Blotch Ray
  • 1 (?) Whipray
The Tank is only 240,000 Gallons so it doesn't seem like there'd be much room left still. I was thinking maybe more Rays but they specifically said Sharks so. Now they never specified they'd be new species, so they could be more White-tip Reef Sharks for example, but I'm expecting the unexpected lol

Yeah that’s arguably too many sharks already for that size of a tank. You did mention in another thread (I think) that they may be sending/considering sending some of those to Seattle Aquarium, which, if they did, that would maybe open things up. But realistically, those are the only tropical Pacific species that would make a whole ton of sense for a tank that size. It’s too small for silvertips and those are pretty tricky to acquire, same goes for most other larger species. I’m certainly fascinated to see where it might go as well.

Yeah that's been my theory / hope lol, specifically some of their Black-tips and maybe Grey Reefs. Also my cope since the original plan at Seattle was 26 or 27 individual elasmobranchs, and so far we only 8 (I don't even know about the Black-tip situation anymore so I won't count them) (also the Javanese Cownose Rays but I'm not sure on how many are being imported)

A safe bet might also be more smaller species such as another species of Catshark or Carpet Shark for the "Lagoon" since that space only has 2 Epaulette Sharks and 2 White-spotted Bamboo Sharks and there's definitely more room in that tank if they wanted to add a couple more. A little funny that the Zoo is still the Elasmobranch hotspot here in the state even after the expansion at the aquarium

I think it could certainly be some combination of both for the Ocean Pavilion sharks haha. And yeah, that is a little funny, but I suspect it'll change once things have kind of settled out with the new exhibit. It takes a little time usually for compatibility and sourcing to get figured out, and there was some pressure to get your guys' exhibit open after how long it had been in development. Georgia's Sharks: Predators of the Deep is kind of an exception to that rule, but that was an elasmo focused exhibit and even then, it took a while for them to get the mix of sharks exactly right (initially, they had three tiger sharks rather than one, for example).
 
Stopped by for a quick visit today, here are a few updates:
  • Extremely exciting news, there are now 2 Big Skates (Beringraja binoculata) in the "Northwest Waters" tank in the Pacific Seas Aquarium. I didn't even notice them until one swam up next to me, it was a real surprise. This is really exciting since this is the first time in (I wanna say over 5 years) that either Seattle or PDZA has exhibited Skates so I'm really happy to see some here. (Hopefully we can get some at Seattle). They're on the smaller side so hopefully they'll be around for a while.
  • All 4 of the Nurse Sharks have now moved into the "Baja Bay" in the Pacific Seas Aquarium
  • Because of that, the Napoleon Wrasse (Cheilinus undulatus) is back on exhibit in the "Outer Reef" tank in the Tropical Seas Aquarium. I'm guessing it'll take some time to move in the other Elasmobranchs since that's a more delicate process. They did update the signage to reflect this, removing the Nurse Sharks and adding the Tasseled Wobbegong on there (they didn't add the Black Blotch Ray for some reason, I will have wait and see or ask someone)
  • The Leaf Insects, Chacoan Horned Frog, and Corn Snake are all off exhibit in the "Kidz Zone" (they do move the Corn Snake off exhibit during the Winter though, not sure why the other two are off exhibit)
  • They're currently building a new "Children's Maze" in front of the old Elephant Barn that will be a limited time attraction for the Spring. I wonder if this is to give them time as to what to go with for Suki's old area.
 
Stopped by for a quick visit today, it's been lightly raining the whole day so not everyone was out. However here are some updates I have;

Tropical Reef Aquarium (I got to talk to an aquarist)

  • Unfortunately, she did confirm that the Black Blotched Ray (Taeniurops meyeni) was "humanely euthanized". She couldn't say why, but said "she wasn't doing well in the habitat". Makes me wonder if she sustained an injury because I'd imagine if she wasn't adjusting, she could've been moved to another facility. Pretty sad about this one since I like the species.
  • On a better note, she did confirm that the Tasselled Wobbegong (Eucrossorhinus dasypogon) and the alleged Aussie Whipray (Himantura australis) were added to the "Outer Reef" a few weeks ago. Both are incredibly shy however, so no one really sees them as they hang out towards the back. Hopefully the Whipray at least gets more outgoing over these next few weeks.
  • There is a Powder Blue Tang (Acanthurus leucosternon) now in the artificial Mangrove Tank next to the Touch Pool, and the Green Spotted Puffer (Tetraodon nigroviridis) was removed (I'm guessing it could've became a bully and started picking at other fish, not uncommon for them to do that)
  • There is now a Blackfin Hogfish (Bodianus loxozonus) in the "Lagoon" (I'm going based off the ID that iNat gave me so I could be wrong). Also apparently there was an adult Yellow Boxfish (Ostracion cubicum) also in the "Lagoon" via a post the Zoo had reposted, but I didn't see it today. Along with now 2 more of the juvenile Orbicular Batfish
  • The "Coral Reefs Up-close" tanks are filled with water, sand, and rock. No animals as far as I could see through the barrier cracks, but it should be opening soon. If I had to guess, May most likely.
Pacific Seas Aquarium
  • The Japanese Spider Crab* is currently off exhibit (there's only one left so I'm guessing it could be molting, or maybe it's moved or passed. I believe the Zoo will be getting more)
  • Most excitingly, there is now a California Moray (Gymnothorax mordax) back in the "Coastal Kelp Forest" tank I saw today. This is the first time in at least 4 years I believe since one has been on exhibit. It's definitely new since they added some new artificial caves in the tank as well. Very excited that the signage is now accurate.
  • There are actually 3 Spotted Ratfish in the "Northwest Waters" tank. The larger 2 have been there for a while, but this 3rd smaller one went in at the same time as the Big Skates (who are still there)
Rocky Shores
  • Walrus were off exhibit today due to habitat maintenance (it was only for today though so they should be back tomorrow)
  • Balzak (walrus) is currently going through a hormone change (I forgot the term but it's something males go through around breeding season, which would be now) so there are some extra barriers around the viewing to give more space
  • The Harbor Seals were also off exhibit today, I'm not sure why but I wonder if they're introducing them to "Riley" who came from Riverbanks a while ago. Which the Zoo still hasn't officially announced on socials.
Arctic Tundra
  • Freya (Arctic Fox) was also off-exhibit today, I'm guessing it could be because of the rain. Hopefully nothing serious, and that Sven is back soon with her.
  • It's probably because of the rain but the pond that is next to the Musk-Ox viewing was filled back up today. Again, probably because of the rain because it's been drained for so long but it could be something to look out for. I can't even remember what they kept in here but it is technically an enclosure so maybe some rehabilitated water fowl could go here.

That’s really really sad to hear. I trust that an injury was indeed the reason because AZA certified facilities don’t just euthanize if there’s no other option. Tragic nonetheless.

Yeah between this and the Hammerhead deaths being so close to each other, it doesn't make for a good image to the general public but things happen. As far as I can remember, I don't think they've ever housed Rays in this tank until the renovation. The old iteration was just sharks, so they might be going through a learning curve with the Rays, just unfortunate it ended with the passing of the Blotch Ray. If it wasn't adjusting well, I'm not sure why she couldn't have been moved to Seattle, so it had to have been a pretty severe injury (hopefully)
 
It's not too uncommon to euthanize fish if they're not adjusting or have just grown too large for the exhibit to either transport or properly care for. I'm not sure what happened in this situation, but it does happen for non-life threatening reasons.

Monterey euthanized a number of their large tuna when the Outer Bay exhibit was renovated in 2011 because they were simply too large to move safely.

Sad, but not uncommon.

In that particular case there wasn’t any other facility that could take them, either. In this case there are multiple facilities within not even 100 miles that could take this particular species…it would be a true shame if it was done without all options exhausted but yeah, it’s not impossible that what you mention is what happened.
