Thanks for the info. I have found some more:
It is a snake whose common name is Nauyaca real velvet, Also known as yellow beard , its scientific name Brothrops asper. It is a snake subtropical areas of Central America, its name derives from " Nahui "meaning four, and " yacatl "meaning nose or the respiratory system has four pits, is actually two receivers and two thermal mass graves passages, which look like four noses.
It is the viperids the most potent poison Mexico, can measure 2 mAre very nervous , they're always on the defensive against any provocation. Rural workers are more supportive of accidents with the Nauyaca , especially in the legs, causing necrosis , edema, other syndromes, even death. Affected people should be treated immediately, Mexico has very good anti-venom but often can not reach it. It encourages people to take these animals home , or work in places where there Nauyaca find out the poison and how it applies . It is a common terrestrial snake in the Chiapas region in Mexico.
Its habitat is Central America South America and the West Indies , is very common to find refuge in the sugar cane plantations . During the day curled up on itself , blending with the surroundings , night out to find food and when it becomes dangerous. It thermoreceptors allowing you to continue in the darkness the trail of heat that leaves a possible warm-blooded prey .
There are many species , is the real nauyaca ( Brothrops asper ), the jumper ( Brothrops nummifer ) , cold ( Brothrops godmani ) of tabs ( Brothrops schlegii ).
So it is a viper - I am surprised, most viper bites look horrible!
anyone got any good pics or accounts off death from cobra, krait, taipan, mamba, coral snake? Or australian venomous snakes _ I think they are all elapids?
