Taxonomy

The taxonomic status is pending for approval

Description

The Red-necked Keelback is one of the few rear-fanged snakes that are potentially dangerous. This species has an average size about 80 – 130 cm and usually found near water. It has an attractive reddish neck. The colour of the body is uniform pale brown or olive green. Its head is olive-green and a reddish neck with the black line extended from the eyes to the upper lip. There is yellow band separating between the olive-green head and reddish neck for the juvenile specimens (Sibunruang et al., 2013). It preys mainly on frogs and toads. The interesting thing about this species is its can extracts toxins from its prey like the Asian Toad (Bufo sp.) and processes the poison to become lethal.
