Sea Anemone; Actiniaria

You should treat every Sea Anemone with respect when scuba diving or snorkelling. They are nice to look at but not to make contact with! Many Actiniaria are also hosts to some of Koh Phangan’s smaller crustaceans and fish.

Night Anemone; Alicia sansibarensis

Boring by day; spectacular by night!

Swimming Anemone; Boloceroides mcmurrichi.

This sea anemone gets all over the place and comes in a wide range of colourations and sizes (from very small to almost medium) !

Adhesive Sea Anemone; Cryptodendrum adhaesivum

It is so named because it is sticky to the touch (so we hear; please do not try it yourself !).

Burrowing Anemone; Not Edwardsia species.

Rarely seen because it is very small and disappears quickly under the sand if alarmed.

Magnificent Anemone; Heteractis magnifica

Definitely well named - a magnificent life form!

Hormathianthus tuberculatus

A small, previously unidentified Actiniarian - seems to be quite variable in shape and habitat.

Isactinia citrina

All the variations of this small, innocuous Actiniarian apparently go by the same name.

Phymanthus species

We thought that the frilly one was a type of Hells Fire Anemone until corrected by some real Actiniarian experts - a shame, as we like the name!

Haddons Anemone; Stichodactyla haddoni

A commonly encountered, short-tentacled, host anemone.

Mertens Carpet Anemone, Stichodactyla mertensii

Can spread over large areas of shallow coral reef.

Other Sea Anemones

Another Carpet anemone, Corkscrew tentacle anemone, Glass tentacle anemone, and more.
