The Sigbin or Sigben is a creature in Philippine mythology said to come out at night to suck the blood of victims from their shadows. It is said to walk backwards with its head lowered between its hind legs, and to have the ability to become invisible to other creatures, especially humans. It resembles a hornless goat, but has very large ears which it can clap like a pair of hands and a long, flexible tail that can be used as a whip. The Sigbin is said to emit a nauseating odor.
According to the legend, there are families known as Sigbinan ("those who own Sigbin") whose members possess the power to command these creatures, and are said to keep the Sigbin in jars made of clay. The Aswang are said to keep them as pets, along with another mythical creature, a bird known as the Wak Wak.
There is speculation that the legend may be based on sightings of an actual animal species that is rarely seen; based on the description of the Sigbin in popular literature, the animal species might be related to the kangaroo. With the recent discovery in the island of Borneo of the cat-fox, a potential new species of carnivore described as having hind legs that are longer than its front legs, it has been postulated that reported sightings of Sigbin may actually be sightings of a member or relative of the cat-fox species.
