Many older references to this species are probably misidentifications. Usually grows to about 12mm, and probably feeds exclusively on the hydroid Eudendrium.

Of particular interest is the demonstration (Morrow et al, 1992) that 'Doto coronata' is probably a complex of similar looking species, each feeding on a different species of hydroid. The photo here (see message below) from the Netherlands is of particular interest because the original description was based on a specimen collected on Eudendrium from the Dutch coast.

See Doto sp. 8 for specimens which look like Doto coronata from the east coast of Nth America.

Re: Characteristic feature of Doto coronata

From: Peter H. van Bragt

Hello Katy and Bill,
As discussed in previous messages, I send you two scans of an in situ image of Doto coronata. The picture was made in the Oosterschelde, the Netherlands in March 1999. The enlarged section shows clearly the pigmented inner face of the cerata, which I consider to be a characteristic feature of this species. This feature is also mentioned by Bernard Picton in his Field Guide of the Nudibranchs of the British Isles.

Best regards
Peter H. van Bragt

Thanks Peter,
Bill Rudman
