Janolus hyalinus - natural history

June 30, 2001
From: Bernard Picton


Dear Bill,
To accompany my other message, on the identity of Janolus hyalinus, here is an in situ photo of an animal on its food, and a photo of an egg ribbon.

PHOTOS:
UPPER: on bryozoan colony Scrupocellaria. Sep 1985 - Boreray, St. Kilda, NW Scotland
LOWER: Egg ribbon. Aug 1980 - Lough Hyne (Ine), Co. Cork, SW Ireland. PHOTOS: Bernard Picton.

This St Kilda animal is more brightly coloured than usual, with a tinge of orange on the cerata. St. Kilda is offshore, with very clear water and many of the animals there seem to be extra brightly pigmented. I suspect that the bryozoan food may not be Bugula as stated in Thompson and Brown but Scrupocellaria as in the
upper (in situ) photograph.
