Monterey Bay Aquarium Major deep sea animal exhibit coming to MBA

Apologies if its a lot to ask for, but does anyone have a species list of what is currently onshow in Into the Deep?

Thank you so much for sharing this, that is really helpful!
 
Forgot to say this earlier but as of April 21 some new species have been added (or readded) to the exhibit.
Rhizophysa siphonophores from Hawaii have replaced the common siphonophores, this is the only other siphonophore to be displayed at Monterey besides the commons. Two pretty nice-sized colonies were on display.
Phyllosoma lobster larvae have been added to the tank with the mauve stingers.
Some specie of tube-dwelling amphipods are in the muddy bottom tank.
 
I may have missed some rotations since the aquarium doesn't really announce them unfortunately but thanks to George Matsumoto (and the aquarium for posting them today), the Bumpy Jellies (Stellamedusa ventana) are back on display! This is only the second ever time they've been on display in the a public aquarium (the first was when they were displayed back in December). It looks like 2 or 3 individuals this time again.

As far as the other jellies go, it looks like mostly everything from the list Splendens provided is still there thanks to a user from the MBA discord server from a few days ago besides the Bolinopsis which the Bumpy Jelllies should've replaced, and the undescribed 'Red X' Comb Jellies are back on display, most likely replacing the Snow Globe Jellies that were previously in that tank.

There was also this story the aquarium put out a while ago that goes more in depth on the care of the 2 Australian Ghost Sharks in the Whale Fall Tank.

In this video they just put out, it looks like there are officially a new batch of Bone Worms (Osedax spp.) on exhibit! This trip just happened 2ish weeks ago so they're pretty new. I'd try and view them ASAP since they seem to only live for a couple of weeks / months before they die-off when all of the nutrients from the bone are depleted.
 
Does MBA plan to bring back the sea angels to the deep sea exhibit? IIRC this species is popular in Japanese aquaria, but is still relatively unknown in North America. They sort of resemble underwater faeries.

They do but they're more of a seasonal display since they only show up in the Bay during Spring, usually they go on display around April and are on exhibit for a few months after that. I'm actually unsure if they were on display this year at all but that's what I was told by some of the husbandry staff
 
The Monterey Bay Aquarium recently posted a list of the staff's top 10 animals that the aquarium has displayed. Glad to see nudibranchs at #4! I never thought gastropods would rank among my favorite animals until I discovered these critters. And from their Into the Deep exhibit, the giant isopod is #8.

I'm a little surprised no other Deep Sea species were on the list but to be fair, those other species are ones the aquarium has consistently had on display for decades as opposed to a few years (like most of the Deep Sea species). Excited to see how that list looks like in another 5 to 10 years.

Also on the Nudibranchs, I know the aquarium was working with at least one (unspecified) species a few years ago (mentioned in the NYTimes Article), but I'm guessing they haven't been on exhibit yet because dedicating one of the benthic tanks to just Nudis wouldn't be the most interesting move to the average guest. I wonder if there's any hitchhikers in any of the Coral tanks, I'll have to look out next time. But the California Sea Owl (Pleurobranchaea californica) wouldn't be that unexpected to see since they're not strictly deep sea (90ft at the shallowest, which is still deep but more than obtainable)

The giant isopod is a Deep Sea species
 
From what I can find recently, it looks like the Bumpy Jellies were taken off a little while ago and were rotated with the Red Spot Comb Jellies so those should be on exhibit. There were some place holder Sea Gooseberries on display in the Siphonophore Tank from one video I saw, but it looks like the Siphonophores are back on exhibit.

Which leads me to my next piece of news that's really interesting since it's only a couple days old. This story from MBARI was just released yesterday talking about their partnership with the aquarium, and it highlights some unique pieces of info:
  • The species of Bolinopsis Comb Jelly that are on exhibit quite frequently are now confirmed as the Short Lobed Comb Jelly (Bolinopsis microptera)
  • It looks like just as of a few days ago from my findings, the Nanomia Siphonphores were split up and a few new species came out of it. Now, instead of being "Nanomia bijuga", the Common Siphonophores on exhibit are confirmed to be Nanomia septata, which were previously confused with N. bijuga. I'm guessing the Aquarium's specimens helped with the separation of the species.
  • THREE more collection trips are planned for this Fall, which means we will most likely see an influx of new species potentially on exhibit which is always exciting.
  • "An extended expedition trip" is planned for next year, which is vague but intriguing. Maybe we'll get a hint at a new exhibit since it's been a while from when Tentacles closed.

I love retroactively being able to tick a species. Glad I took note of everything!
Really cool species and it's great to see that further work is being done to determine exactly what they have.

I'm guessing since they already had the signage made, they couldn't edit it since the exhibit signage still has them as Bolinopsis infundibulum, but it looks like they figured out they were actually B. microptera in October '22 according to this tweet. I wonder if they'll update that.

Besides new species, I hope we see another appearance of the Dinner Plate Jelly since those were on the team's radar to collect more now they're able to take care of them, and also the Red Paper Lantern Jellies since those haven't made an appearance since '22 I think and have only been exhibited two times. I would love to see that species again. With the colder weather coming in, more species might be migrating up at night due to the lower temperatures so I'm really excited to see what'll be on exhibit these next few months

The midwater rotation at least seems to be the same for now (Bloody Bellies, Purple Lipped Jellies, Crown Jellies, Abyssal Comb Jellies, Common Siphonophores, Short Lobed Comb Jellies, "Red X" undescribed comb jellies. There's been no footage of the small circular tank next to the Bloody Belly tank but I'd have to guess its probably Mauve Stingers).
One cool thing I caught though was the Crown Jellies currently on display (Nausithoe sp.) are most likely an undescribed species according to the signage someone on facebook posted. MBARI is currently doing research on them to describe the species.
Also wondering whenever we'll see the Giant Red Mysids on display since in theory, they'd fit into that circular tank where the edges are visible.
Really hoping I can make it back down next Spring. Perhaps the Balloon Worms will be back with the Sea Angels. Waiting for the next ground breaking species to make an appearance in the exhibit soon...

Via someone in the MBA discord who visited a few days ago:
  • Tower Jellies (Neoturris spp.) are back on exhibit, this species was absent for a while so nice to see it make an appearance
  • The Abyssal Comb Jellies were moved from the larger cylinder tank to the smaller, round circular tank. No mention of what took up space in the cylinder tank but if i had to guess it's probably the Lobed Comb Jellies or Red Spot Comb Jellies (based on track record)
Nothing else seems to have really changed but by now based off the MBARI article, the aquarium should've been on 3 more collection trips so maybe we'll see some new species pop up.
 
Via the Aquarium's Instagram, the Sea Angels are back on exhibit (a little earlier this year than I was expecting since usually they go on exhibit around March).
I believe the Crown Jellies used to be in that tank (not 100% sure since I haven't been back in 2 years) but I would guess those are off exhibit now.

Take this with a grain of salt since this is the only mention I've seen of it
It looks like as of this past Tuesday, a Japanese Porcupine Crab (Paralomis histrix) is on exhibit in the Benthic gallery. The poster says the photos were taken the same day so I'll take his word for it and say it' should be accurate.

This would be the first time since the grand opening that the species has been on exhibit.

Edit: thanks to @ Rye on the MBA discord, it's confirmed there are 3 Japanese Porcupine Crabs on exhibit. Not sure which species they've replaced however, but that's cool to see a grouo since during the grand opening there was only 1

What are the chances that they are going to get another vampire squid to put on exhibit?
