A rather long post. For people not reading it all, I guess the major non-fish news for most zoochatters are breeding olive sea snakes, breeding moriche oriole, and highland streaked tenrec now kept offshow.
Four earlier questions in this thread that hadn't been fully answered:
* How big are the Philippine crocodiles? Small, 1-1.5 meter long. At least 4 individuals.
* Will the sea otters breed or are they subjected to the same restrictions as all the captives in USA, which also are rescues owned by US Fish and Wildlife? The restrictions put in place for US sea otters also apply to the ones in Blå Planet. I believe they said the male or female was sterilized, but I barely heard it and it might be medical contraception instead. The sea otters that recently arrived in Brest (France) are also US-based and presumably subjected to the same restrictions.
* Why the rock pillars in the large North Atlantic ocean/sea bird tank? Apparently they are supposed to be an immitation of basalt pillars seen at a bird colony on a North Atlantic island. I didn't hear the exact island, but they are quite similar in form to the columns in Hofsos in Iceland and Frodba in Faroe (mostly grey, but also have reddish sections). I wish they'd explained that at the exhibit, as I was unaware of the existence of such columns until a recent visit to Iceland and only heard what the Blå Planet exhibit was supposed to represent when I specifically asked a keeper. Earlier I just assumed it was an unfortunate example of "artistic freedom" in an exhibit, unlike anything in the wild.
* How big is the piranha tank? I don't have an exact number, but did see a publication saying "more than 100,000 liters" and that seems about right.
Some news. Unless otherwise noted, I saw these species on my last visit. Note that this actually is based on a visit several weeks ago; some things might have changed.
Full list of birds currently kept (in North Atlantic tank, above African Great lakes and in rainforest): Atlantic puffin, common eider, Inca tern (in North Atlantic tank since 2016! However, apparently only on temporary loan from another zoo to test some free-flight issues in the tank), white-eared turaco, violet turaco, common emerald dove, red-flanked lorikket (unsigned in rainforest; may leave unless they can find a mate to their single male with the goal if reducing his aggression; he has attacked nesting passerines), scarlet-headed blackbird, moriche oriole (unsigned in rainforest; only arrived earlier this year but already bred successfully), red siskin, green honeycreeper (unsigned in rainforest; recently bred but failed; see red-flanked lorikeet for reason), red-headed parrotfinch, Gouldian finch, black-cheeked waxbill, zebra waxbill, Cuban grassquit (in rainforest, unsigned).
Full list of mammals currently kept: Sea otter, highland streaked tenrec (not seen by me, but kept offshow and apparently sometimes taken out for show-and-tell; short video on their instagram), Seba's short-tailed bat, some gerbil species (offshow).
Full list of reptiles & amphibians currently kept: Philippine crocodile, olive sea snake (bred last month; only the second time this species has bred in captivity, after the first success at Reef HQ in Australia earlier this year), boa constrictor (offshow, sometimes out for show-and-tell), corn snake (offshow, sometimes out for show-and-tell), plumed basilisk (unsigned, free-living in rainforest), veiled chameleon (unsigned, free-living in rainforest), greater Madagascar day gecko (unsigned, above African lakes exhibit), alligator snapping turtle (the scientific work validating
M. apalachicolae as a separate species has been questioned, and as a consequence Blå Planet now list theirs as
M. temminckii again, although recognizing that it is the Apalachicola morphotype), mata-mata turtle, West African mud turtle, pig-nosed turtle, axolotl, edible frog, common toad, tomato frog (free-living in rainforest, good luck seeing it!), red-eyed tree frog (unsigned, free-living in rainforest, good luck seeing it!), Golfodulcean poison frog (like all poison frogs in rainforest, only signed to group), golden poison frog (like all poison frogs in rainforest, only signed to group), yellow-banded poison frog (like all poison frogs in rainforest, only signed to group), harlequin poison frog. Not a reptile/amphibian, but there are apparently also free-living and breeding vampire crabs in the rainforest (did not see them and you'd need a lot of luck!).
Fish news, mostly (this is not a complete list, just some of the news; I'm not repeating anything I already mentioned in my post at the bottom of
Zoos that are the only one to hold a species. [all in that post are on-show]): giant guitarfish have been re-identified (
Rhynchobatus australiae, was
R. djiddensis; however there are strong indications that their small ones actually are a third species - several new
Rhynchobatus species have been described in recent years and possible undescribed species remain), short-tailed nurse shark (offshow as part of a research project by Copenhagen University, don't know if they'll go on-show), coral catshark (offshow),
Rhinopias scorpionfish (offshow and my view was too brief to identify exact species), several interesting poeciliids offshow (for example, Montezuma swordtail and undescribed species; the on-show aquarium that formerly held Montezuma is now home to the Xalapa form of green swordtail and adjacent has cardinal brachy), Russian sturgeon sign has been corrected (had scientific name
A. sturio, now correct
A. gueldenstaedtii), blue whale catfish (offshow, but apparently supposed to go on-show later), North Pacific section has turned into a deep ocean section with giant Pacific octopus, Japanese spider crab,
Paralomis hystrix crab, yelloweye rockfish and longspine snipefish (other North Pacific animals have moved to North Atlantic tank [wolf-eel, canary rockfish, quillback rockfish, copper rockfish, masked greenling, kelp greenling, cabezon, padded sculpin] and North Atlantic small animals [giant green sea anemone, unsigned], but this is apparently temporary), South American lungfish,
Potamotrygon tigrina stingray,
Campylomormyrus numenius elephanfish,
Brycon amazonicus characid, zebra shovelnose catfish, giant raphael catfish, Kelber's peacock bass,
Guianacara owroewefi cichlid, gulper catfish (I was lucky to see it in one of the large rainforest tanks; luck necessary!),
Crenicichla cincta pike cichlid (only arrived a few months ago, already bred, might be first in the world?),
Crenicichla johanna pike cichlid, giant tanganyika cichlid, big-mouth hap cichlid, Malawi trout cichlid,
Dimidiochromis strigatus cichlid (easily missed as the aquarium also holds the very similar Malawi eyebiter),
Benthochromis tricoti cichlid,
Phenacogrammus aurantiacus tetra, longfin tetra, banded ctenopoma, eyespot synodontis,
Synodontis filamentosus catfish, black-spotted synodontis,
Synodontis soloni catfish,
Acestridium dichromum catfish (offshow, but apparently just moved on-show; good luck seeing it!), Nile puffer, Burmese archerfish (offshow), swallowtail seaperch.
Because of the fairly large offshow sections there are undoubtedly species I missed and some of these may move on-show later. For example, despite offshow visits I had completely missed the fairly large zebra shovelnose catfish, a species that only recently was put on-show, but apparently had been offshow for a year. It also makes it a bit tricky to figure out if a species isn't kept anymore or just moved offshow.
Major species that I'm fairly certain are no longer at the collection: African dwarf crocodile, panther chameleon, tassled wobbegong, Australian lungfish, Amazon leaffish, Tanganyika lates, bigeye lates.
