In the fresh (to say the least) seafood section, there was all sorts of live stuff, most of which I easily recognized as eels, crabs, frogs, etc., but one creature baffled me.
They looked a little bit like frogs, but without legs–or maybe something like very lumpy fish. They were writhing around in a container, without water, though they seemed kind of damp-to-moist. (The frogs were up to their eyeballs in water, but not these guys, who were definitely alive, though maybe not for long.) They were brown and spotted, with shiny skin. They were about the size of large frogs.
This was in Flushing NY if that helps.
