What is this clam-like thing in food stall? And this eel-like thing in food stall? [w/ images]

Yeah, about the display. Gosh, next to them are incredible pulsing razor clams at absurdly low prices. Ditto conchs and geoducks (neither of which I’ve had).

It should be a law that pronunciation guides are printed whenever the animals are mentioned. I only learned a few years ago.

So, to fight ignorance:

[conk]
[goo-y duck]. I would love to see an etymology of that pronunciation. It is totally incomprehensible to me. A shibboleth of the fish community, undoubtedly.

*“Etymology of that pronunciation:” there must be a real word for this.
