The bearded fireworm is a strange marine creature that looks like a centipede on first glance (especially when seen on land like this specimen).
You will usually see them underwater, they are actually a tyle of marine bristleworm growing up to a maximum of 30cm in length.
The creature moves slowly but you should take great care not to accidentally touch it since its bristles contain a powerful neurotoxin that causes burning and intense irrtation as well as occasionally nausea and vomiting.

Christmas Tree Worm (Spirobranchus giganteus)
Observed: Koh Chang Reefs, December 2015
Observed By: Jonathan Milnes
The brightly-coloured spiral-bodied christmas tree worm is a type of tube-building polchaete worm.
These worms live inside rocky tubes that they build withing coral structures. They emerge from these tubes to feed, gathering in microorganisms using their tree-like array. When threatened though they whip rapidly back into their rocky home and disappear in a flash. A fun sight for divers and snorkellers.
