Poder da pezoña
A pezoña sae polos seus cairos ou dentes cando morde.
Que fai a súa pezoña?
The urutu is highly venomous. Its venom mainly contains phospholipase A2, snake venom metalloproteinases, snake venom serine proteases and C-type lectins. In one study of 32 patients, all had local pain and swelling, 97% had prolonged blood clotting, 41% had bleeding (usually from the gums), 32% had blistering and 9% had necrosis (death of tissue).1
Que perigoso é para as persoas?
Perigo para as persoas: Moi perigosoPode matar a unha persoa que non reciba tratamento.Bites are an important cause of snakebite in its range and often cause severe local tissue damage, but they are rarely fatal. In a survey of 6,601 snakebite cases in Central and South America, 384 were attributed to this species, and 8 of those (2%) were fatal. Some bites have caused gangrene that required amputation, and in 2004 a 44-year-old woman died of a brain bleed after being bitten at home.1
Boas novas: os médicos teñen un medicamento (antiveleno) ou un tratamento para isto.1
Se morde
- In one Brazilian hospital study, all 32 bitten patients were treated with specific antivenin (antivenom), and none of them died.1
- Mantén a persoa quieta e tranquila, mantén o membro mordido á altura do corazón, quítalle aneis e cousas apertadas e vai rápido a un hospital.

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
Genome sequencing found 59 toxin genes from 16 toxin families.1
Its verified maximum length is 169 cm, although reports of over 2 m exist.1
Some unusual individuals have dark stripes running the full length of the body.1
In some specimens the pattern is so concentrated that the markings and the gaps between them are the same colour.1
Females are significantly longer and heavier than males.1
