About Coryphella cooperi Cockerell, 1901
Coryphella cooperi (Cockerell, 1901) has a translucent white body, with a stripe of white surface pigment running along the middle of its back. This stripe forks in front of the rhinophores, and may continue onto the oral tentacles. Small white pigment spots are present on the outer sections of both the oral tentacles and rhinophores. The cerata hold a green digestive gland, and have a scattering of white spots on the outer part, below the cnidosacs.
