This one is for my sister. She’s a diver and this little creature is her absolute favorite thing to find. This is just one of many varieties of nudibranch and she loves them all.
Hermissenda crassicornis is a species of small, brightly-colored, sea slug or nudibranch, a marine opisthobranch gastropod mollusk in the family Glaucidae. This species is also commonly known as the “opalescent sea slug.” The species grows to be about 50 mm, or about 2 inches. The color of this nudibranch varies from one locality to another, but it is always easily recognizable by the orange stripe along its back.
Taken at Lincoln Park, West Seattle, Wa., during a very low tide. This nudibranch was skimming the bottom of a cockle clam shell.
