Let’s be honest: I’ve never seen that many nudibranchs on one dive. Even though it was always the same dorid (Glossodoris sedna), the nudi population seems to be flourishing around Socorro Island, Mexico. Cabo Pearce and Punta Tosca are literally covered with these tiny fellas and yet 90% of the divers completely miss them.
