Common names: Russell's sand boa, rough-tailed sand boa,[3] Common sand boa.

Eryx conicus, also known as Russell's sand boa, the Common sand boa or the rough-tailed sand boa, is a species of non-venomous snake in the subfamily Erycinae of the family Boidae. The species is native to Southern Asia. No subspecies are recognised.[4]

Description

E. conicus

Adults of G. conicus may attain a total length of 3 feet 3 inches (99 cm), which includes a tail 3 inches (76 mm) long.

The anterior maxillary and mandibular teeth are longer than the posterior. The head is covered with small scales. The eye is small with a vertical pupil. The dorsal scales are small and keeled. The tail is pointed, not or but very slightly prehensile.[5]

The

Subcaudals: 17-24.[5]

The anterior dorsal scales are only feebly keeled, but these keels increase in size posteriorly to the point that they become so heavily keeled that it can make a squirming specimen really painful to handle. This also makes it look as if the front and rear ends belong to markedly different animals.[6]

Dorsally, the color pattern consists of a broad zigzag band or a series of dark brown blotches on a yellowish or brownish grey ground color. The belly is uniform white.[5]

In India it can be mistaken at first glance for either the Indian python (Python molurus) or the deadly Russell's viper (Daboia russelii).

Behavior

E. conicus is active at dusk and at night.[7]

Diet

E. conicus preys upon birds and small mammals, which it kills by constricting.[7]

Geographic range

E. conicus is found in

type locality given is "India orientali ".[2]

Mimicry

The rough-scaled sand boa's color pattern frequently resembles that of the highly venomous

herpetologists believe is a case of Batesian mimicry.[8]

Reproduction

E. conicus is viviparous.[9]
