The Conception Bank silver boa (Chilabothrus argentum), also known as the Conception Bank boa or silver boa, is a species of boa[1][3] described in May 2016 by a team of researchers from Harvard University led by Dr. R. Graham Reynolds.[2][4] It is only known from the Conception Island Bank in the Bahamas.[1] It is the first known discovery of a West Indian boa species in 73 years.[4] It is named for its unique silver color and the fact that the first specimen was found in a silver palm.[2] It is the most endangered boa in the world, with fewer than 250 individuals in an area of just 5 hectares.[5]

Description

[edit]

Conception Bank silver boa has silver to tan dorsal background coloration, with or without scattered dark brown scales. Ventral scales are pure cream-white. They measure 88–103 cm (35–41 in) in snout–vent length and weigh 182–258 g (6.4–9.1 oz). Tail length varies between 18 and 21 cm (7.1 and 8.3 in).[2]

Habitat and biology

[edit]

The Conception Bank silver boa is largely arboreal and has been found in silver palm Coccothrinax argentata and gumbo-limbo Bursera simaruba. It is thought that the species mostly feeds on birds, with juveniles possibly feeding on Anolis sagrei lizards. [5][6]

Conservation

[edit]

The species is known from six individuals encountered in July 2015 by a research team from Harvard University, and from the type series of two individuals collected in October 2015. A total of 49 individuals have been observed by researchers between 2015 and 2017. [5]

It has been assessed by the International Union for Conservation of Nature (IUCN) and is considered "Critically Endangered"[1] in view of its small area of occurrence as well as potential threats posed by introduced species, habitat loss, and (illegal) pet trade[7]. Some level of protection is offered by the Conception Island Bank being designated as a national park, and by the relative remoteness of the islands.[2]

[edit]

The Conception Bank silver boa is a featured part of the story in T.C. Boyle's novel Blue Skies[8]. The discovery of the Silver Boa and researcher R. Graham Reynolds are featured in the book Bill Nye's Great Big World of Science.[9]
