Mantle glands in Ceratosoma magnifica? from the Red Sea

May 8, 2007
From: Bill Rudman

In Binyamin Koretz's message [#19871] about Ceratosoma magnifica I meant to draw attention to the mantle glands which can be seen as small whitish swellings around the tips of the lateral lobes at the mantle edge. It is quite difficult to see the mantle glands in some species of Ceratosoma, and in this species they seem to be concentrated at least in the tips of these lateral 'lobes' along the mantle edge. I suspect they are probably in the median horns as well. While the more 'typically' shaped species such as C. trilobatum, C. gracillimum and C. tenue, concentrate the glands - and the antifeedant sponge metabolites they contain - in their single postero-dorsal horn, the species with lateral lobes appear to concentrate glands in those as well. A good intermediate is Ceratosoma moloch which has a posterior horn and gland-filled lateral lobes [Rudman, 1988].
