Sagaminopteron psychedelicum from Taiwan

From: Bernard Picton


Hi Bill,
Here are two photographs showing Sagaminopteron psychedelicum from Taiwan, March 1983. This is an enlargement of a photo I sent earlier of Chromodoris orientalis. I think both the chromodorid and Sagaminopteron psychedelicum may both be feeding on the dull red sponge which they are sitting on. If I had to guess I'd say it looked like an Oscarella species
(which have no spicules).

Thanks Bernard,
Perhaps 2002 could be the year that someone presents us with good evidence of just what gastropterids feed on. To me, the shape of their teeth makes it quite unlikely that they feed on sponges, and if they do, why haven't they been found in the act of feeding? I know that they are often found on sponges, but so are species of Trapania and from your observations we know know that they feed on entoprocts which live on sponges.
Best wishes,
Bill Rudman
