Concerning message #14792:

Dear Bill,
I'm sending you a new picture I took today, and I think it is Siphopteron michaeli.

Locality: Hermitage beach, 0,5 metre, Reunion Island, Indian Ocean, 29 october 2006. Length: 3 mm. Photographer: Hugues Flodrops.

It was very difficult to find it because of its size. Perhaps the substrate in the algae is its food and it may be a good place for hiding.
Best regards.
Hugues.

Dear Hugues,
Thanks for the photo. I think the algae it is on is a species of Padina. The white layers you can see are bands of calcification and I am pretty sure that Padina is the only genus of brown algae that has a calcified skeleton like this. It is certainly possible that there are some small animals living in the algae which Siphopteron feeds on. Unfortunately we seem to have no clues on what they are!

Best wishes,
Bill Rudman
