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 around the United Kingdom and France. It is a marine gastropod mollusc in the family Dotidae.

Distribution[edit]

This species was described from Devon, England. It is commonly found in the North Atlantic Ocean around the coasts of the United Kingdom and France.[2] It has been reported, probably in error, from around the South African coast where it is found from the Atlantic coast to Knysna. The South African species is known from the intertidal to 30 m.[3] The South African specimens are quite different in appearance to specimens from the NE Atlantic and are likely to be an undescribed species and will be referred to here as Doto cf. pinnatifida.

Description[edit]

Doto pinnatifida is a moderately sized (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 which have black spots in the margin.

The feathered doto, Doto cf. pinnatifida, taken in 25 m of water on the Atlantic side of the Cape Peninsula. Animals about 15 mm total length.

Ecology[edit]

Doto pinnatifida feeds exclusively on the hydroid Nemertesia antennina.[2]
