Agkistrodon bilineatus taylori
- Common names: Taylor's cantil, ornate cantil.
Adults usually attain a length of 64–90 cm (25⅛–35⅜ inches), with some growing to 96 cm (37¾ inches). The subspecies has a heavy body and a relatively long tail: 16-19% of total body length in males and 13-18% in females.
This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001). Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend is unknown. Year assessed: 2007.
Feeds primarily on rodents and amphibians. Juveniles are known to employ the yellowish tip of their tail as a lure to attract small insectivorous vertebrates. The yellowish tip fades as the animals mature, as does this behavior.
Because of their attractive coloration and relatively small size, they are somewhat popular in the exotic pet trade, with captive bred individuals occasionally being available. The care requirements are fairly basic, similar to A. contortrix. These snakes are, however, not for the inexperienced keeper. The venom is significantly stronger than that of A. contortrix and can cause severe tissue damage and even death if untreated. Dry bites are seldom reported, and these snakes may strike repeatedly.
