The blue sea dragon is a small, bright blue sea slug that floats upside down on the open ocean. It drifts with winds and currents in warm and temperate seas around the world. It is special because it steals stinging cells from the animals it eats and uses them as its own weapon.1

Warm and temperate oceans worldwide, including South Africa, Europe, eastern Australia, Brazil, India and Thailand1
Atlantski ocean, Tihi ocean, Indijski ocean

It lives in the open ocean (the pelagic zone) and is carried by winds and currents. Because it sometimes washes up on shore, people may find it on beaches, for example in Thailand, Spain and Texas.1

Kako jo prepoznaš

  • Usually around 3 cm long1
  • Floats upside down at the surface, with its blue side facing up1
  • Silvery grey on its back, which faces down in the water1
  • Dark blue stripes on its head1
  • Six finger-like, feathery appendages called cerata1

Pogosto zamenjujejo z: It is closely related to G. marginatus, which is now known to be four separate species living in the Indian and Pacific Oceans. It also shares the name "blue dragon" with Pteraeolidia ianthina and G. marginatus.1

Moč strupa

Piki

Strup pride ven skozi želo.

Kaj naredi njen strup, ko ugrizne ali piči?

It does not make its own venom. It takes the stinging cells (nematocysts) from the Portuguese man o' war and stores them in its cerata, a process called kleptocnidy. Because it concentrates this venom, its sting can be stronger than that of the animal it eats. Symptoms can include pain, nausea, vomiting, a rash, redness and blisters.1

Kako nevarna je za ljudi?

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

Picking up the animal can cause a very painful sting that may be potentially dangerous. Its sting produces symptoms similar to those of the Portuguese man o' war.1

Kaj naredi, ko se prestraši?

It stores stinging cells from its prey in its cerata and uses them against predators.1

Če piči

  • Imobilizacija s pritiskom: čvrsto ovij elastični povoj čez ugriz in nato navzgor po celem udu, ud imobiliziraj z opornico in poškodovanca drži popolnoma pri miru, dokler ne pride pomoč.
  • Modroobročkasta hobotnica ali stožčasti polž lahko človeku ustavi dihanje, medtem ko je še pri zavesti: pokliči pomoč in bodi pripravljen dajati umetne vpihe, dokler reševalci ne prevzamejo.

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

Dejstva

1

It can eat the Portuguese man o' war without harm, because it is immune to that animal's stinging cells.1

2

It floats upside down because its gas-filled stomach sac sits on the wrong side of its body, so its foot becomes its upper surface.1

3

Its blue colour is thought to reflect harmful ultraviolet sunlight.1

4

Its countershading, with blue on top and silver-grey below, helps it hide from predators above and below.1

5

It can lay up to 55 egg strings per hour.1
