![]() Asilomar, Monterey Co., CA; 4 June 2008; 11mm total length. |
Description: Ground color translucent cream-white, with no dark pigment on body. The 5-8 opposite pairs of cerata bear numerous rather long, well spaced tubercles which occur in 4-7 (sometimes indistinct) rings around each ceras, cores vary from pale yellow, or light pinkish-orange or orange-brown. Rhinophores & calyciform rhinophore sheath with numerous small, opaque white dots. The lack of dark pigment distinguishes this species from Doto columbiana & Doto kya both of which have dark pigment on the body. May be distinguished from Doto form A which has comparatively longer and whiter papillae on the cerata, and cerata cores bright pink to salmon or rose |
