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

Ahabanza

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

Koga, ikigereranyo cy'ugereranyije

Irya iki?

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

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

Niba itera urubori

Sohoka mu mazi kandi ukureho imirya yayo (tentacles) yose ukoresheje uturindantoki cyangwa igitambaro.
Ku box jellyfish zo mu turere dushyuha: suka vinegere aho zateye urubori nibura amasegonda 30, hamagara ubutabazi kandi witegure gukora CPR (gukanda igituza no guhumekera umuntu). Ku bluebottle no ku zindi nyinshi: oza n'amazi y'inyanja, hanyuma ukoreshe amazi ashyushye kubera ububabare.

Irinde akaga

Ntuzigere ukora, ufata cyangwa ushotora inyamaswa yo mu gasozi, nubwo yaba ntoya, kandi nubwo yasa n'isinziriye cyangwa yapfuye.
Yihe umwanya. Niba uhuye n'imwe, tuza, usubire inyuma buhoro buhoro kandi uyireke yigendere.
Niba imwe igutereye urubori: tuza, ntunyeganyege, hamagara nimero y'ubutabazi (112, 000, 911) cyangwa ujye ku bitaro vuba. Ibuka uko yasaga, ifoto irafasha.

Ntigushakisha ngo ikugirire nabi. Ikoresha ubumara bwayo kugira ngo ifate ibyo kurya cyangwa yirinde, kandi ikunda cyane kwihisha. Ibindi ku kwirinda

Ibintu by'ukuri

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
