Overview

Comprehensive Description

Description

Doto pinnatifida is one of the largest species of the genus Doto, large individuals reaching 30mm in length. It is characterised by black tipped tubercles on the sides of the body and on the cerata. Occasionally there are a few of these tubercles on the dorsum. The rhinophore sheaths have a series of black spots around the edges. The only other Doto species with tubercles on the body is Doto tuberculata, a smaller animal with tubercles arranged in irregular rows across the back, between the cerata.

The sole prey of this animal is the hydroid Nemertesia antennina. The spawn is a long pleated ribbon, laid on the stem of the hydroid.

Feathered doto

The feathered doto, Doto pinnatifida, is a species of dendronotid nudibranch, and is found off South Africa, the United Kingdom and France. It is a marine gastropod mollusc in the family Dotidae.

Contents

Distribution

This species is found in the North Atlantic Ocean off the United Kingdom and France. Around the South African coast it is found from the Atlantic coast to Knysna. It is known from the intertidal to 30 m.[1]

Description

The feathered doto is a small (up to 30mm) pale-bodied nudibranch, with darkly mottled nodular clusters of cerata extending in pairs down the body. The rhinophores extend from cup-like sheaths.[2] May be confused with the crowned doto, Doto coronata, but the cerata of this species are more elongated and less grape-bunch-like than those of the crowned doto.

Ecology

The feathered doto feeds on hydroids. Small coiled white egg masses are often laid on hydroids.
