The yellow-bellied sea snake is a sea snake with a strongly venomous bite. It lives in warm tropical oceans and spends its whole life at sea, floating on the surface. Its yellow belly and brown back make it easy to tell apart from most other sea snakes.1

Živi v
Tropical oceans across the Indo-Pacific, the Pacific coasts of the Americas, the eastern coast of Africa, and parts of the Atlantic and Caribbean through occasional strays.1
Tihi ocean, Indijski ocean, Koralno morje, Južnokitajsko morje, Filipinsko morje, Andamansko morje, Arabsko morje in Perzijski zaliv, Timorsko in Arafursko morje, Bengalski zaliv, Kalifornijski zaliv
Domov
It is a free-floating ocean snake that drifts on surface currents, often along oceanic drift lines and in floating mats of sea kelp. People most often meet it when it is washed up on beaches or caught in fishing nets.1

Kaj je?
It hunts pelagic fish that come to the surface to shelter. It floats still on the surface to attract them, then catches prey with a backwards swimming motion and a rapid lunge of the jaws.1

Kako jo prepoznaš

  • Sharply bicoloured: black or dark brown on the back, with a yellow or brown underside.1
  • The yellow belly may have black spots, bars or crossbars, or a narrow black stripe along the back.1
  • Has a flattened, paddle-shaped tail for swimming.1
  • Adults are usually up to about 72 cm (males) or 88 cm (females) long.1

Moč strupa

Ugrizi

Strup pride ven skozi strupnike ali zobe, ko ugrizne.

Kaj naredi njen strup, ko ugrizne ali piči?

The venom is highly potent and contains several different neurotoxins, which attack the nerves, along with two other isotoxins. Sea snake venom can damage skeletal muscle, which may release myoglobin into the urine (myoglobinuria), and can cause neuromuscular paralysis or direct kidney damage. Juvenile venom is on average less concentrated than adult venom.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: ResnoPo ugrizu je potreben zdravnik. Smrtni primeri so zelo redki.

Bites are rare. The most common victims are fishermen who try to remove the snakes from fishing nets. No deaths have been recorded from bites in Australian waters.1

Dobra novica: zdravniki imajo za to zdravilo (protistrup) ali zdravljenje.1

Kaj naredi, ko se prestraši?

It is not considered aggressive but will defend itself if threatened.1

Če ugrizne

  • The venom is neutralised with sea snake antivenom (Enhydrina schistosa). If that is not available, tiger snake or polyvalent antivenom should be used.1
  • 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.
  • Poškodovanca spravi iz vode in hitro v bolnišnico.

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 ugrizne: 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 swim backwards, which is an unusual ability and a distinguishing feature of this species.1

2

It breathes partly through its skin, taking oxygen from seawater while diving and swimming at the surface.1

3

It can survive severe dehydration for up to 7 months during seasonal drought.1

4

Large groups of thousands have been seen floating together on the surface in oceanic drift lines.1

5

It is the only sea snake known to have reached the Hawaiian Islands.1

6

Strays wash up so often on New Zealand's coasts that it is considered native to the country and protected under the Wildlife Act 1953.1

Razbijalec mitov

Mit: Sea snakes drink seawater and filter out the salt through a special salt gland in the lower jaw.

Resnica: Sea snakes drink only fresh water. The salt gland was once thought to filter salt, but it is not used for that purpose. The yellow-bellied sea snake likely drinks from freshwater lenses that form on the sea surface after heavy rain.1
