This is the "Christmas Tree" Eyelashed Palm Pit Viper so favored by hobbyists.
Last week we discussed one of the more rarely seen of the Palm Pit Vipers, the Yellow-blotched, B. aurifer. This week let’s take a brief foray into the world of what is probably the best known and most variable member of the genus, the 2 to 3-foot long Eyelashed Palm Pit Viper, Bothriechis schlegelii. This is a slender snake with a strongly prehensile tail. The supraorbital “eyelashes” are legend. Despite being venomous, the variability of color and patterns and the fact that this snake is hardy attracts many hobbyists to this lowland Central American and northern South American pit viper.

Color? You name it. This snake can vary from the dullest of grays, with or without darker patterning, to the brightest of sunshine yellow, again with or without patterning. The gold-phase is often referred to as the “Orapel,” Spanish meaning gold and glittery. Then there are the greens, gray-greens, dull greens, or a hobbyist favorite, the “Christmas tree phase, this latter being a bright green with reddish patterning. The tiger phase, a golden snake with broad green banding is also a favorite.

This is a humidity loving snake that in its forested habitat may often be found at about face-level along bush and tree-shrouded watercourses. There it quietly waits for prey that includes small arboreal rodents, treefrogs, lizards and birds.

Along with the already mentioned attributes, hobbyists are now taking pride in designing enclosures for this quiet snake as rainforest replicas with living plants, perches, and occasionally with mini-waterfalls. Humidity is good, wetness is not.
I’ll close here by saying that although this is often a “laid back” and quiet species, as with any venomous snake, extreme care should be used when maintenance and or handling becomes necessary.
