Oxynoe panamensis is a species of small sea snail or sea slug, a bubble snail, a marine gastropod mollusk in the family Oxynoidae.


Oxynoe panamensis is found in mangrove swamps along the Baja, California and Mexico coasts.[2] The type locality for this species is Bocas Islands, Panama.[3]

Life habits[edit]

This species feeds on Caulerpa sertularioides, a green siphonaceous algae. When irritated, Oxynoe panamensis excretes a potent, milky toxin from its skin.[2] There is known autotomy of the tail under persistent mechanical irritation.[2]
