Costasiella iridophora [Costasiella iridophora]

Description

Divers may spot this tiny sea slug as a small, often iridescent-looking nudibranch clinging to algae or reef surfaces. Its subtle colors can shift in the light, making it easy to miss—until you notice the delicate, jewel-like sheen. Look closely on rocky substrates where it can blend in with its surroundings.
