Concerning message #2015:
Here are 3 Halgerda carlsoni observed at "Ile Ste Marie" on the East Coast of Madagascar.
The orange colour seems to be more brilliant and the black rhinopores look different than the East Africa Halgerda.
Locality: Ile Ste Marie, 15 - 20 m, Madagascar, Indian Ocean, october 2008. Length: 20 - 40 mm. Photographer: Sully Bachel.
These Halgerda seem to be common on this island.

I suspect the paler colour in the photos of the animals from Tanzania are because they are a little over exposed. A photo from Sth Africa [message #3623] shows a much brighter coloured animal. All the western Indian Ocean animals, including yours, show the black on the gills and rhinophores as lines, while animals from the Pacific have black spots, so the two may turn out to be distinct species.
