Pleurobranchus membranaceus egg-laying frenzy

June 15, 2006
From: Jim Anderson

Dear Bill,
Apart from seeing polycerids recently [see message #16874], we are experiencing a Pleurobranchus membranaceus egg laying frenzy at a sea loch site on the west coast of Scotland I dived on Sunday last - dozens of large egg masses and animals still spawning, mating, feeding and just hanging about - all in 6-10 m over the sandy, stony bottom. They have been around since Feb with the first spawn masses in April.
Regards,
Jim A

Dear Jim,
Thanks for this information. From your earlier message [#7001] in May 2002, it would seem this breeding 'frenzy' is a regular occurrence in your Spring. We have quite a few examples of Sea Hares with such 'mass events' [see Population Fluctuations] but there are examples to be found throughout the sea slugs, but they are just not usually as noticeable.
Best wishes,
Bill Rudman
