SEA ANEMONES (Actiniaria)
MAGNIFICENT ANEMONE (Heteractis magnifica)
Exposed on hard substrates of drop-offs and slopes. The color is variable, tentacles greyish with yellowish tips.
Lives in symbiosis with clown fishes.
GIGANTIC SEA ANEMONE (Stichodactyla gigantea)
Settles from close to surface down to 30 m.
The body is smooth and folded. The carpet-like tentacles have strong stings.
BUBBLE ANEMONE (Entacmaea quadricolor)
Very common at the Similans, but often unnoticed, because hidden in cracks on hard substrates.
The tentacles are swollen at the tip. Occurs in many different colorations, depending on the zooxanthellae.
CROWN JELLYFISH (Rhizostomea spec.)
Length: to 50 cm
These jellies have a thick, fluffy frill between the upper bell and lower tentacles.
The central frill underneath actually contains numerous mouths, that are particularly efficient for trapping small organisms from the surrounding water.
