The fandrefiala is a spear-headed snake in Malagasy mythology. The Malagasy believe this arboreal snake drops tail-first from trees while stiffening its body like a spear to stab people or Zebu cattle passing below. The ‘clever’ fandrefiala is also said to miss his target and to invariably kill itself in the fall.
This snake is in fact known to modern science as Ithycyphus perineti, it does have V-shaped head-markings that suggest a spear but is totally harmless.
Another bizarre snake is the spear-nosed snake, Langaha madagascariensis, which mimics a twig with its unusual nasal appendage.
