Sea snail found depositing eggs and boar fish sighted

February 26th, 2008

Lamellaria have been found depositing eggs in Guernsey and Boar fish have been reported in Jersey and Dorset.

On Guernsey’s east coast, Belle Greve Bay, Lamellaria were found excavating holes in ascidians in order to deposit their eggs. Lamellaria has a shell of 10mm length and the animal can grow up to 20mm. This slug-like mollusc varies in colour; yellow, grey or lilac and often with coloured flecks of yellow, black or white. Lamellaria have internal shells enclosed by a mantle which is covered in tubercles. Lamellaria feeds on ascidians and lays their eggs in capsules deposited in holes eaten out of the ascidians by the female. Each flask-like capsule is holds up to 3000 eggs!

In Jersey and Kimmeridge bay, Dorset, Boar fish or Capros aper have been sighted. Capros aper is an oval fish, growing up to 30cm in size. They vary in colour from brick-red for individuals from deep water (200m or more), sometimes with yellow bars, to a yellow-straw coloured fish in shallower waters. It has small, rough scales and feeds on molluscs and crustaceans.
