Feeding observations on Armina sp. 9

From: Leanne & David Atkinson


Dear Bill,

We came across these small Armina feeding on a seapen. It was unusual because it was at 9:45am on a bright sunny day in clear water. We only usually see Armina's in late afternoon or night. We were very pleased with these shots of one feeding and thought it might be useful for the forum. Can you please help with a name for them? They don't seem to have the same markings as our usual Armina cygnea.

Locality: Little Beach, Port Stephens, NSW, Australia. Depth: 8 metres. Length: 50 mm. 9 April 2005. Sandy bottom with scattered sponges & soft corals. Photographer: Leanne & David Atkinson

Dear Leanne & David,
Thanks for these great photos. If we had any doubt about what these fed on, your photos certainly remove any doubt. This is not one of the usual species you find in Port Stephens. It lacks to orange border to the oral veil and also the oral veil has rows of yellow -tipped papillae on each side. It also lacks the yellowish rhinophores. There are many species of tropical arminids which need to be sorted out so at present I'll call it Armina sp. 9.
Best wishes,
Bill Rudman
