Unfortunately there is nothing worth mentioning about this species on the net,

except that it can be found down to a depth of 100 metres.

I was kindly given the name of the animal by Ron Silver from the USA.

The following text is from a friend of reeflexicon.

Such animals can hardly ever be identified on the basis of a photo.

They are simply too heavily camouflaged with everything possible.

No body structure / special features can be seen.

What is certain is that it is a spider crab, family Epialtidae,

most likely a Hyastenus sp. - Hydroid spider crab.

Possible and relatively frequently documented are e.g.

Hyastenus bispinosus

Hyastenus borradailei

Other species are also possible, such as Lahaina ovatus....

She is great at identifying marine animals, but here she reached her limits.

I have now set it like this. Thanks a lot to you

Hides between polyps of soft corals.

The body colour ranges from white, yellow to red or pink,

depending on the colour of its host coral.

The crab camouflages itself by attaching soft coral polyps to and on its carapace.

There are small claws on the first pair of legs and larger spines on the body,

which are translucent with a red and white pattern.

This species looks like a Halimeda alga and is therefore very well camouflaged against its predators.
