The Christmas tree hydroid is a small, branching sea creature that grows in colonies on rocks and hard surfaces in shallow water. It is found in warm seas around the world, and it is common in the Mediterranean Sea. Scientists have used it to study how animals catch their prey.1

It grows in shallow water, attached to hard surfaces such as rocks and man-made structures, in places with some water movement. On reefs it is usually found in less-exposed spots and in crevices. It has also spread on ropes and other structures placed in the sea.1

Ɛdi deɛn?
The polyps spread their tentacles to catch small zooplankton that drift past. Stinging cells on the tentacles immobilise the prey, then the crown bends over and the prey is killed and pushed into the mouth.1

Contact with a rope on which this hydroid was growing caused an acute, painful skin inflammation (dermatitis) in several people. Contact with the stinging cells on its tentacles is the cause.1

1

It has spread around the world largely through people's maritime activities, by attaching to ships and structures.1

2

It has been used in research into how animals capture their prey.1

3

Colonies grow by budding, which forms new feeding polyps.1

4

Its free-swimming larvae drift with the plankton before settling on a hard surface.1
