Adult Tritonia manicata from Atlantic Spain

Hi Bill,
I see you just posted a picture of Tritonia manicata. I think these dark spotted animals are juveniles. I enclose a couple of pictures of a larger animal which has quite different coloration. I'd be interested to know if the Mediterranean workers have seen these changing colour as they grow, as
does Tritonia hombergi. Luis Sánchez Tocino has a similar animal on his website. [http://www.ugr.es/~lstocino/welcome.htm]

My photo was taken at Ria de Arosa, Galicia, NW Spain. July 1978. Intertidal. 15mm.
