Has segments with short tufts of white bristles

and red branched gill filaments.

Colour: Brown, green and red.

in crevices or under coral fragments and stones.

When threatened, the worm raises its bristles,

which easily penetrate the skin and then break off.

This leads to burning pain and itchy wounds.
