Swarming of Stylocheilus striatus at Bonaire

November 7, 2005
From: Les Wilk

Dear Bill,
In response to the swarming Stylocheilus messages [#15175 ],  I didn't know there was such a thing as "swarming sea hares" until we witnessed such an event in April 2004 on the Caribbean island of Bonaire. There were several huge aggregations a few meters apart, joined by narrow trails of marching hares. A couple of days later they were gone.

Dear Les,
I don't think anyone in the world knew just how widespread this phenomenon is in Stylocheilus, until reports started appearing on the Forum. Some of my colleagues don't think the Forum is 'science' but it looks like the creation of new knowledge to me.

April is certainly a bit earlier in the year than the June/July reports we have had before from the Caribbean for Stylocheilus swarming, which again demonstrates just how little we know.
Best wishes,
Bill Rudman
