Not in the wild

Omastar

Gold
Apparently, it cracked SHELLDER's shell with its sharp fangs and sucked out the insides.
Silver
Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs.
Crystal
Its heavy shell allowed it to reach only nearby food. This could be the reason it is extinct.
