Calliophis salitan
Calliophis salitan is a species of venomous snake in the family Elapidae. It is endemic to the Philippines and known from Dinagat Island and Mindanao; the former is based on a small number of recent records whereas the latter is based on a museum specimen from 1887.
It is unique for its large size as well as its body coloration of a black head & neck with black & white bands along the width of the body, terminating at a bright orange tail. It is distinct from any other coral snake species in the Philippines or Sundas, but is most closely related to the blue coral snake complex of the Sunda Shelf. While it is known only from Dinagat Island and possibly Mindanao, it may also occur or have formerly occurred on other islands in the Sulu Archipelago.
