Distribution

This species was first described from the Canary Islands. It has subsequently been reported from the Caribbean coast of Costa Rica,[2] Barbados[3] and Panama.[4]

Description

The body is short and narrow.[4] Rhinophores are smooth and with opaque white dots.[4] Rhinophoral sheaths are with small frontal extensions.[4] Cerata are large with rounded tubercles; apical tubercles much larger than the rest.[4] The cerata are translucent blue, and the ceratal tubercles have no dark spots and contain dense concentrations of rounded hyaline glandular structures.[5] Background color is translucent gray with a series of dark brown spots on the dorsum.[4] Cerata are with dark brown branches of the digestive gland and bluish tubercles.[4] This dendronotid nudibranch is translucent white with mid-sized black spots scattered over the top and sides of the body.[5] In the internal base of the ceratal peduncle there is a black mark below the three-lobed transparent pseudobranch.[5]

The maximum recorded body length is 5 mm[4] or 6 mm.[6]

Ecology

Minimum recorded depth is 1 m.[6] Maximum recorded depth is 4 m.[6]

Doto escatllari was found associated with small hydroids[4] of the family Sertulariidae; these are probably its prey.
