Sibynophis sagittarius, commonly known as Cantor's black-headed snake after Theodore Cantor, [4] [5] is a species of snake endemic to South Asia. [3]
It is found in central and northeastern India, Bhutan, Nepal, and Pakistan. [3] It is uncertain whether the species occurs or has occurred in Bangladesh. [6]
Adults may attain 28 cm (11 in) in total length, with a tail 6 cm (2.4 in) long.
As the common name implies, the dorsal surface of the head, including the nape of the neck, is black or dark brown, followed by a thin yellow nuchal collar. Also, there are two large elongate yellowish spots, one on each side of the back of the head. The upper surface of the body is pale brown, and the sides of the body are darker brown or gray. On each flank there is a thin black stripe separating the differently colored areas. A series of small black dots, widely separated, run down the vertebral row of dorsal scales. The underside is yellow, with a black dot at each outer end of every ventral.
The smooth dorsal scales, which lack apical pits, are arranged in 17 rows. Ventrals 205–228; anal plate divided; subcaudals 56–70, divided (paired). [7]
It is not arboreal, but rather hunts by day on the forest floor. [5]
An oviparous species, it lays a clutch of as many as six eggs. [5]

Ptyas mucosa, commonly known as the Oriental rat snake, dhaman or Indian rat snake, 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.
