Etymology

edit

Both the specific name, jayakari, and one of the common names, Jayakar's sand boa, are in honor of Atmaram Sadashiv Jayakar (1844–1911), an Indian surgeon and naturalist.[4]

Description

edit

The Arabian sand boa is a small snake growing to a total length (including tail) of about 38 cm (15 in). The eyes are very small and are located on the top of the head, which has a blunt snout and is wedge-shaped. This snake's colour is yellowish-grey or sandy-brown speckled with white flecks and transversely banded with dark marks.[5]

Geographic range

edit

The Arabian sand boa is native to the Arabian peninsula. Its geographic range includes Saudi Arabia, Oman, Yemen, Kuwait, and southern Iran, where a small number of specimens have been found in Khuzestan Province, Bushehr Province and Kerman Province.[1]

Habitat

edit

Eryx jayakari is a desert species of snake, living semi-underground in sand or soft soil.[1]

Behaviour

edit

The Arabian sand boa is largely nocturnal and is tolerant of a wide range of temperatures. During the day it buries itself deep in the sand but moves towards the surface at dusk. Here it remains slightly below the surface with just its eyes projecting, ready to pounce with a sideways flick of its head, on any small creature that happens to pass.[5] Its prey includes short-fingered geckos (Stenodactylus spp.), the Baluch rock gecko (Bunopus tuberculatus), and worm lizards.[6]

Reproduction

edit

Unlike other members of the Boidae family, the Arabian sand boa lays eggs instead of giving birth to live young.[7] The only other Boidae species known to do this is the Mullers sand boa.

The female lays a small clutch of eggs which hatch in about 66 days at a temperature of 33 °C (91 °F).[6]

Hatchlings don't develop an egg-tooth which would help them break out of their shells when they are ready to hatch, instead the mother helps her babies open their shells.[7]

Conservation status

edit

The Arabian sand boa is listed by the IUCN as being of "Least Concern". This is because it has a very wide range, is common in at least parts of that range, and no particular threats have been identified.[1]
