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

Vive en
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

Inicio
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

Que come?
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

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: GraveUnha mordedura precisa un médico. As mortes son moi raras.

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

Boas novas: os médicos teñen un medicamento (antiveleno) ou un tratamento para isto.1

Que fai cando ten medo?

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

Se morde

  • The venom is neutralised with sea snake antivenom (Enhydrina schistosa). If that is not available, tiger snake or polyvalent antivenom should be used.1
  • Inmobilización con presión: envolve cunha venda elástica firme a mordedura e despois todo o membro cara arriba, ponlle unha férula e mantén a persoa completamente quieta ata que chegue a axuda.
  • Saca a persoa da auga e lévaa rápido a un hospital.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te morde: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

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

Desmontamitos

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

Verdade: 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
