Bothriechis Guifarroi
''Bothriechis guifarroi'' is a species of venomous green palm pitvipers discovered in 2010 in the Texiguat Wildlife Refuge, in Northern Honduras. ''Bothriechis guifarroi'' joins two other species of the genus ''Bothriechis'', ''B. marchi'' and ''B. thalassinus'', found in the Chortís Highlands of Honduras. Its color pattern and scalation is similar to other Honduran palm pitvipers, but genetic analysis reveals it to be more closely related to the '' B. lateralis'' and '' B. nigroviridis'' species more than 600 km to the southeast, in the mountains of Costa Rica and Panama. Description Adult ''B. guifarroi'' are brightly colored green, with a yellowish hue towards the ventral side. The juveniles have a green phase and a brown phase, before acquiring the adult coloration. The holotype (adult) measured 734 mm total length, with a tail length of 136 mm. Distribution The population of ''B guifarroi'' was found at elevations between 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agkistrodon Piscivorus Conanti
The Florida cottonmouth (''Agkistrodon conanti'') is a species of venomous snake, a pitviper in the subfamily Crotalinae of the family Viperidae. The species is endemic to the United States, where it occurs in southern Georgia and the Florida peninsula in nearly every type of wetlands in the region, including brackish water and offshore islands. However, it is not entirely dependent on water and is occasionally encountered as far as a mile (1.6 km.) from surface water. ''Agkistrodon conanti'' venom is very hemolytic and known to cause relatively extensive necrosis compared to many snake venoms, and can sometimes be lethal with a 17% mortality rate.
