Keen's Tritonid

Tritonicula myrakeenae

Keen's Tritonid is a species of dendronotid nudibranch found in the family Tritoniidae. This species has a distinct appearance that can help divers identify it among similar nudibranchs. It is typically reported from California, USA, and Baja California, Mexico, extending down to Costa Rica. The type locality is the Southeast end of Isla Cedros in Baja California, where it inhabits rocky reefs. These nudibranchs are often found in shallow waters, where they can be observed clinging to rocky substrates. Keen's Tritonid primarily feeds on small invertebrates, which it grazes from the surfaces of its rocky habitat. The breeding habits of this species are not extensively documented, but like many nudibranchs, it is likely to be hermaphroditic, possessing both male and female reproductive organs. Encounters with this species during dives can be intriguing, as divers may spot them slowly moving along the reef, showcasing their unique form and coloration. While specific conservation status details are not provided in the sources, divers should remain mindful of their environment to help preserve the habitats where these nudibranchs thrive.
