Concerning message #5688:

Well, if those guys are doing a conga line, I guess these guys are doing a waltz? Actually, knowing the way nudibranchs spawn head-to-tail, it's probably more like an orgy. Whether or not the huge bunch of egg ribbons are the result of this convention or another, I don't know.

Thanks Dave,

If you look at the other messages concerning Onchidoris bilamellata you will see that mass movements mass matings and egg laying seem to be part of this species' way of life in much of the temperate waters of the northern hemisphere.

Best wishes,
