Boiga is a large genus of mildly venomous, opisthoglyphous or rear-fanged, colubrid snakes typically known as the cat-eyed snakes or just cat snakes. They are primarily found throughout southeast Asia, India and Australia, but due to their extremely hardy nature and adaptability have spread to many other suitable habitats around the world. There are 34 recognized species in the genus.
Cat snakes are long-bodied snakes with large heads and large eyes. They vary greatly in pattern and color. Many species have banding, but some are spotted and some are solid-colored. Colors are normally black, brown, or green with white or yellow accents.
Invasive species:
Boiga irregularis in particular has been federally banned in the United States because of its effect by accidentally being introduced to the island of Guam. Some time during the 1950s, these snakes (or possibly a single female with eggs) reached the island, possibly having hidden in imported plant pots. The island of Guam lacks native snakes or predators that can deal with snakes the size and aggressiveness of Boiga irregularis. As a result, they have bred unchecked as an invasive species, and began consuming the island's bird life in extreme numbers. Currently, dozens of bird species have been completely eradicated from the island, many species that were found nowhere else on earth, and the snake has reached astonishing population densities, reported to be as high as 15,000 snakes per square mile. In addition to devouring the native fauna, this species will routinely crawl into power transformers, and, unfortunately for all involved, this typically results in both an electrocuted snake and substantial blackouts.
