Asian worms

Still trying to track down a few worm IDs from the last couple of trips, any help even to the family level would be appreciated.

(1) Flatworm from Racha Noi in Thailand:

All the rest of the photos are from Lembeh Strait:

(2) nocturnal bristle worm:

(3) nocturnal worm:

(4) rather a vicious looking critter, IIRC it was active at dusk:

(5) Is this the feather duster worm Protula magnifica?

TIA,

Richard.

The first flatworm is Thysanozoom sp. Flatworms don't have all the names yet!

Great pictures Richard!

The feather duster worm is probably from the family Sabellidae and is the Bispirra sp.

I found these worms also in de Philippines.

Hi there -

The first is in either genus Acanthozoon or Thysanozoon. There's a whole suite of species with this general appearance and it's hard to tell which is which.

Second is a fireworm in the genus Chloeia.

Third I'm not sure about but the reticulated pattern & shiny skin make me think it's a sipunculid worm.

Fourth is a polychaete, family Sabellariidae. Someone once sent me one of these which I passed on to a specialist. He thought it was a new genus but others feel it belongs to the genus Lydgamis. The two appendages are soft feeding structures fringed with filaments which capture food particles from the water.

Fifth is usually identified as Protula magnifica in the guide books.

Thanks, folks!

Sorry for my belated reply.

Richard.

the bristle worm is beautiful...

I saw some specimens similar to #4 in Anilao, let me see if I have some photos.. it was the first time I had seen a worm like that.

On the bristle worm - I saw one a couple years ago also in Lembeh and my best guess was Chloeia flava. Here's another perspective....
