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

Leef in

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

Tuis

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

Lengte

88 cm (2,9 ft)1

Topspoed

omtrent 3,7 km/h (2,3 mph)

Swem, rowwe skatting

Wat eet dit?

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

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Byt moet deur 'n dokter gesien word. Sterftes is baie skaars.

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

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

Wat doen dit as dit bang is?

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

As dit byt

The venom is neutralised with sea snake antivenom (Enhydrina schistosa). If that is not available, tiger snake or polyvalent antivenom should be used.1
Drukimmobilisasie: draai 'n stewige elastiese verband oor die byt en dan op oor die hele arm of been, spalk dit en hou die persoon heeltemal stil totdat hulp opdaag.
Kry die persoon uit die water en vinnig na 'n hospitaal.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

die moeite werd om te weet

Feite

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

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

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

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

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

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

Mite-breker

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

Waarheid: 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
