About the Blotched Palm-pitviper

Bothriechis supraciliaris, commonly known as the blotched eyelash-pitviper, is a species of venomous snake in the subfamily Crotalinae of the family Viperidae. The species is endemic to southern Pacific parts of Talamanca Mountain Range in Costa Rica and western Panama.

Bothriechis supraciliaris is usually 50–60 cm (20–24 in) in total length (including tail), but can reach 80 cm (31 in). Its body colour varies. It can be either bluish-green, reddish-brown, or reddish-maroon, but usually it is bright-green or moss-green. The body is circular, ovoid and rhomboid in cross-section, with irregular dorsal blotches, that sometimes form crossbands. The belly is light. There are 21–23 dorsal scales rows at midbody. The head carries dark stripes and prominent scales that are located above the eyes.

The only sexual dimorphism noted is that females of the species tend to be longer and thicker than males. The geographic range of B. supraciliaris is limited to southern Costa Rica (between San Isidro and San Vito) and western Panama. All of its range overlaps with that of the closely related species B. nigroadspersus. Bothriechis supraciliaris... Wikipedia →
