Doto coronata
Doto coronata is a species of small sea slug or nudibranch, a shell-less marine gastropod mollusc in the family Dotidae. It is the type species of the genus "Doto". Doto coronata sensu lato. 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. Species with translucent white bodies and red or black spots on the cerata which were formerly identified as "Doto coronata" include: Distribution. The type locality for this species is on the Dutch coast. A specimen from near  Goes, Eastern Scheldt, Zeeland was designated as a neotype in a recent review of the genus "Doto". 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. It was erroneously reported from around the South African coast where it is found from the Atlantic coast to Knysna and this species has been described as "Doto africoronata". Description. This species is a small nudibranch, with grape-bunch-like clusters of cerata extending in pairs along the sides of 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. The maximum recorded body length is 15 mm. Ecology. Minimum recorded depth is 4 m. Maximum recorded depth is 27 m. "Doto coronata" feeds on hydroids, especially "Obelia" spp. Campanulariidae and "Sertularia cupressina" 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)
