Here are a few pictures of an Armina sp. from the Gulf of Thailand. I think it's Armina semperi.
The pictures were taken during the daytime in a sandy, sheltered bay, around 11 metres deep. Several species of sea pen also live in the area.

Thanks for these photos. It is certainly the animal I am calling Armina semperi. I have included a few 'close-ups' to show the detail of the head and rhinophores.
