Description

Lycodon striatus

Lycodon striatus is dark brown or black above, with white transverse spots or crossbands, which are widely separated anteriorly. The sides are lineolated with white, with a black spot corresponding to each white crossband. The upper lip and ventrum are uniform white (coloration in alcohol). The longest adult known to George Albert Boulenger in 1893 was 43 centimetres (17 in) in total length, with a tail 7.5 cm (3.0 in) long. [1]

The head is only slightly distinct from the neck, and the snout is flattened. There are 8 upper labials, the first and second contacting the nasal scale. [2]

Taxonomy

Lycodon striatus was first described in 1802 by George Shaw, as Coluber striatus; its type locality was "Vizagapatam and Hyderabad". Two subspecies are recognised, including the nominate race: [3]

Ecology

Lycodon striatus prefers dry regions such as semideserts and forest edges. [2] Snakes of this species are nocturnal. By day they hide under stones, but after dark they emerge to hunt. [2] Lycodon striatus feeds on skinks, geckos and other small lizards. [2]

Reproduction

Adult females lay eggs in April (in India). Clutch size is small, at only 2–4 eggs, and the egg size is relatively large – 25–30 millimetres (1.0–1.2 in) long by 9–12 mm (0.35–0.47 in) wide. Parental care of the eggs has been observed. [2]

<i>Ptyas mucosa</i> Species of snake

Ptyas mucosa, commonly known as the oriental ratsnake, Indian rat snake, darash or dhaman, is a common non-venomous species of colubrid snake found in parts of South and Southeast Asia. Dhamans are large snakes. Typical mature total length is around 1.5 to 1.95 m though some exceed 2 m. The record length for this species was 3.7 m, second only to their cousin Ptyas carinata among living colubrid snakes. Despite their large size, oriental ratsnakes are usually quite slender with even a specimen of 2 m commonly measuring 4 to 6 cm only around in diameter. Furthermore, the average weight of ratsnakes caught in Java was around 877 to 940 g, though larger males of over 2.3 m may easily weigh over 2.5 kg (5.5 lb). Their color varies from pale browns in dry regions to nearly black in moist forest areas. Rat snakes are diurnal, semi-arboreal, non-venomous, and fast-moving. Rat snakes eat a variety of prey and are frequently found in urban areas where rodents thrive.

They are nonvenomous, but many members of this genus strongly resemble the venomous kraits in appearance, an example of Batesian mimicry.
