Maximum size: 5.2 cm

Maximum depth: 0 - 2 m

This sea anemone is usually found solitary in sandbanks,

in the sand near reefs and in seagrass.

Normally it is completely buried in the sand.

We found this one during a night dive. 

It has very short tentacles that barely protrude beyond the oral disc.

A few rows of tiny bumps can be seen on the oral disc itself.

If it is disturbed, it can partially retract its oral disc into the body column

and bury itself completely.

 They have long tentacles, which are expanded like bubbles at the tips and look like dummies.

13 different anemonefish live with them in a community.

If the fish are disturbed, they withdraw into the anemone.

Although they live solitary, they often settle so densely that they

can form veritable lawns in shallow water.

 The tentacle swellings, which make this species easy to identify,

are strung like pearls on a necklace.

The tentacles stick when touched.

They can be found from the Red Sea to the Pacific.

Found singly in crevices, among coral rubble and on various soft bottoms.

They are among the largest reef anemones in the Red Sea and the Indo-Pacific.

If you touch the tentacles, they stick to your hand,

but are neither dangerous nor painful to human skin.

Six different anemone fishes use them as wits anemones,

and you often see more than one species on the same anemone.

 It can reach a diameter of over one metre, with short tentacles of varying lengths,

but all have the same diameter and end bluntly or pointedly.

Up to twelve different clownfish live in their company.
