Overview

Comprehensive Description

Description

The nudibranchs called by this name are probably an aggregate species consisting of Doto species which share the characteristics of red pigment spots on the tips of the ceratal tubercles and red pigment in the pseudobranch region on the inner face of each ceras. There are red to maroon pigment spots or streaks on the body. The smooth rhinophores have sheaths with dilated margins. The body is translucent white. Typically about 10mm in length. The newly described species Doto hydrallmaniae and Doto sarsiae have only recently been separated from this complex by electrophoretic methods. It is likely that other morphs are also good sibling species.

Doto coronata

Doto coronata, is a species of small sea slug or nudibranch, a shell-less marine gastropod mollusc in the family Dotidae. [1] It is the type species of the genus Doto.

Distribution[edit]

The type locality for this species is on the Dutch coast. It has been reported elsewhere in the North Atlantic Ocean (European waters, Canada, Gulf of Maine) and the Mediterranean Sea (Greece) but many records are likely to be of sibling species.[2] It has been erroneously reported from around the South African coast where it is found from the Atlantic coast to Knysna.[3] It is known from the intertidal to more than 25 m.

Drawing of Doto coronata from Kunstformen der Natur (1904)

Description[edit]

This species is a small (up to 15 mm) nudibranch, with grape-bunch-like clusters of cerata extending in pairs down the body. In all Doto the rhinophores extend from cup-like sheaths. Doto coronata is translucent white in colour with mottling of dark red on the back and sides of the body. The ceratal tubercles are tipped with round red spots. There is a patch of dark red pigment on the inner faces of the cerata.[2]

Doto coronata sensu lato[edit]

Before 1976 a number of species were called by the name Doto coronata and the process of splitting this complex into species was started by Henning Lemche.[4] Species with translucent white bodies and red or black spots on the cerata which were formerly identified as Doto coronata include:

Ecology[edit]

Doto coronata feeds on hydroids, especially Obelia spp. Campanulariidae and Sertularia spp. Sertulariidae. Its egg mass is a white ribbon laid in a zigzag pattern, usually on or at the base of the hydroids it is feeding on. It is a host of the ectoparasitic crustaceans Doridicola agilis Leydig, 1853 and Splanchnotrophus brevipes Hancock & Norman, 1863 and the endoparasitic crustacean Lomanoticola brevipes (Hancock & Norman, 1863)
