Hermissenda opalescens (Cooper, 1863)

This highly photogenic animal is a very common species around the Channel Islands. Its abundance may be related to its varied diet, which is reported to include not only hydroids but other nudibranchs (including members of its own species), ascidians, and jellyfish. It was formerly considered Hermissenda crassicornis.
