Sea animals (ocean animals) in a Chinese supermarket

  There are a lot of sea animals (ocean animals), i. e. marine animals. Many of them are for sale in the Chinese supermarkets. Here come the photos -- marine animals in a Chinese supermarket:
-- I think they're a kind of lobsters.
-- They're so interesting, aren't they? I think they're a kind of razor clams.
, -- This is, probably, a kind of giant abalone.
-- They're some kind of crabs.
-- They're some kind of crayfish, maybe?
-- For sure -- a lobster.
-- I think that they're sea urchins (or urchins (ˈɜːrtʃɪnz)), aka sea hedgehogs.
-- Just some big clams.
-- I think they're called "沙虫" in Chinese, which means "sand worm" ("sand worms")/"sandworm" ("sandworms").
-- a really big crab!
-- imported fish (from Europe, Norway).

  I didn't expect that soon we'll visit this place again and we'll have the opportunity to take some more, new photos of these amazing aquatic (marine) animals.
 Here we go:
- -- interesting long black fish. No idea what's the name of this animal.
- -- another fish, very colorful and pretty. I don't know its name.
- -- big dark fish. No idea about their name.
 And some amazing photos of the marine animals in a big aquarium:

 As we learned today -- some of these animals are Alaskan and some are Australian (according to their names of the tags).
