Doto bella is a species of sea slug, a nudibranch, a marine gastropod mollusc in the family Dotidae.
This species was described from the Izu Peninsula, Japan. It is widely distributed on the Pacific Ocean coasts of Japan and the Japan Sea coasts. A species from Indonesia has previously been identified as Doto bella but is now thought to be an undescribed species.[1] [2]
This nudibranch is transparent white with a diffuse, sub-epidermal layer of black pigment which is faint in some specimens and very dense in others. The ceratal tubercles are slightly stalked with globular tips which have a large black spot which is partly obscured by white glands in the terminal tubercle. The digestive gland is usually yellow. The outer half of the rhinophores is black.[3]
Doto bella has been photographed on a colony of a hydroid, probably in the family Aglaopheniidae on which it presumably feeds.[4]
