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

Domov

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

Kaj je?

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

Kako jo prepoznaš

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

Moč strupa

Piki

Strup pride ven skozi želo.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

Several people who touched a rope covered in this hydroid got an acute, painful dermatitis. No deaths are known.1

Če piči

Pojdi iz vode in odstrani lovke (z rokavicami ali s krpo).
Pri tropskih kockastih meduzah: pike vsaj 30 sekund polivaj s kisom, pokliči pomoč in bodi pripravljen na oživljanje (TPO). Pri portugalskih ladjicah in večini drugih: izperi z morsko vodo, nato pa za bolečino uporabi vročo vodo.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

vredno vedeti

Dejstva

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
