Phyllidiella zeylanica? from east Africa

From: Bernard Picton


Hi Bill,
To accompany the photo of Phyllidiella rosans here are some photos which may be Phyllidiella zeylanica. They were collected at the same time from Pemba Island, east Africa in Feb 1999.

This is the most common phyllidiid in the area (~30mm). It may be fully grown Phyllidiella rosans - but most of the pictures of P. rosans seem to show no cross-bars of black, only longitudinal bars. The tubercles seem to be too low for P. zeylanica but more separate than P. rosans.

Thanks Bernard,
If we go on published information then these are fairly typical P. zeylanica. What of course would be inetersting to know is whether they feed on the same sponge as you have photographed P. rosans on. Hopefully we can gradually build up some more clues as to the just what constitutes as species in this group.
Cheers,
Bill Rudman
