Pleurobranchus forskalii eggs?

May 3, 2005
From: Brian James

A night dive at Abu Nuhas, Red Sea, revealed these wonderful eggs. At first sight I thought Spanish Dancer but, of course, the eggs are the wrong colour. The egg mass was approximately 18cm x 11cm in size and was in 18M of water.

Locality: Abu Nuhas, Egypt. Red Sea. Depth: 18 m. Length: 18cm (approx.)

Can you confirm that they belong to Pleurobranchus forskalii.

Many thanks

Dear Brian,
Although I guessed that the eggs in message #2217 could possibly be those of P. forskalii, it's a bit dangerous to extend that to all large white egg ribbons. For one, this ribbon doesn't have the sinuous folds, and secondly, we just don't know enough about these animals to be sure. If I say they 'probably are', in a little time the word will spread that all large white egg ribbons are Pleurobranchus forskalii, and we will forget that we don't really know. With luck, someone, one day, will find something laying an egg ribbon like this - and have a camera ready to record the occasion - Let's hope they send it to the Forum.
Best wishes,
Bill Rudman
