Christmas tree hydroid
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

- Colonies have many branching stems, up to 30 cm high, arranged in a tree-like shape1
- The stalks are dark brown or blackish, but are often coated with algae and diatoms, giving them a muddy look1
- The tiny whitish polyps are tinged with red1
- Each polyp has many slender tentacles at its base and up to twelve tentacles with knobbed tips around its mouth1

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

Xibaar
It has spread around the world largely through people's maritime activities, by attaching to ships and structures.1
It has been used in research into how animals capture their prey.1
Colonies grow by budding, which forms new feeding polyps.1
Its free-swimming larvae drift with the plankton before settling on a hard surface.1
