are these zoas growing on a clam or oyster?

[reefo420]

I won a bid a few days ago for a zoa colony on a clam or an oyster or something, i've seen a tongue looking thing in it, I'm not sure if it's dead or alive(just very curious,
it seemed to be slightly more open earlier this morning.

Zoyster. Zoanthoyster, Oysthid. Whatever it is, it's joined the Cronenberg genre.

Zoyster is very much alive and respirating, you'll probably have to target feed the oyster portion with a dilute seawater and reefroids mix or a weak phytoculture every couple of days. wouldn't hurt much to begin culturing some anyways.

Assuming the spikes on the right are part of the shell, then I'd guess you've either got some kind of jewel box clam (taxonomic family Chamidae) or spiny oyster (family Spondylidae, genus Spondylus). Super cool find, especially with the zoas on it, but these guys (filter feeding bivalves) rarely do well in our aquaria - good luck with it!
