Shore Pit Viper
Venomous
Trimeresurus purpureomaculatus. A venomous pit viper species. Common names include: mangrove pit viper, mangrove viper, and shore pit viper, purple-spotted pit viper.
A species of mangroves and coastal forests, the Shore Pit Viper has a reputation for being unpredictable and should be approached with caution.
This venomous snake can strike far and rapidly and can be aggressive giving no warning signs, this snake will strike readily at any threat, and its powerful haemotoxic venom can cause serious illness or even kill. By day it can be found resting on low branches one or two metres from the ground. When distressed, it has been observed to shake its tail vigorously against the vegetation, creating a rattling sound.
Body color highly variable: above olive, grayish, to dark purplish brown; below whitish, greenish or brown, uniform or spotted with brown; a light line on scale row one bordering ventrals present or absent; head olive, heavily suffused with brown.
Males grow to a total length of 66.5 centimetres (26.2 in), females 90 centimetres (35 in). The maximum tail lengths are then 12.5 centimetres (4.9 in) and 14 centimetres (5.5 in) respectively.
Scales in 25-27 longitudinal rows at midbody; 11-13 upper labials, the first partially or completely united with the nasal; supraocular very narrow, sometimes broken into small scales, 12-15 scales between them; head scales small, subequal, tuberculate or granular; temporal scales keeled.
Ventrals: males 160-179, females 168-183; subcaudals: males 74-76, females 56-63, paired; hemipenes without spines.
The species ranges from India and Burma, through Thailand and Peninsular Malaysia to Singapore and Sumatra.
It feeds on lizards, frogs and other small animals, possibly small birds. Like other vipers, it has heat-sensing pits on its lips to detect its prey.
A case of envenoming by the shore pit viper (Trimeresurus purpureomaculatus) that showed clinical improvement when treated with the Indian (Haffkine) polyvalent antivenom.
Severe envenoming by the shore pit viper can lead to marked local effects such as extensive swelling and tissue necrosis.
The Indian (Haffkine) polyvalent antivenom contains antibodies against 4 common venomous snakes in India, namely the Indian cobra, common krait, Russell's viper, and sawscaled viper.

Wagler's Pit Viper

Wagler's Pit Viper, or Temple Pit Viper, is perhaps the commonest pit viper in Southeast Asia. It occurs in lowland forest, either primary or secondary, and in some coastal regions may occur in mangrove.
Other names :
Wagler's Temple Pit viper,
Wagler's Pit Viper, Temple Viper, Bamboo Snake, Speckled Pit Viper
Chinese name :
甲蝮蛇, 韋氏竹葉青, 廟蛇, 瓦氏棕櫚蝮, 黑綠烙鐵頭,
蝮蛇亞科 (Crotalinae)
Pit vipers are all venomous, however Wagler's Pit Viper is generally not considered to be aggressive. In the field, these snakes are most easily identified by their markedly triangular head.
Wagler's Pit Viper is generally found resting on low vegetation, but a careful search may also locate the species at mid-canopy level many metres above the ground.
Individuals may remain on the same branch for many days, either as they digest a recent meal, or as they lie in wait for their next meal. Prey is detected at night by means of the heat-sensing pits which occur on either side of the head. Rodents, such as arboreal rats, and birds reportedly make up the bulk of their diet.
Juveniles and males have a slender, lime green dorsum sparsely patterned with pairs of small coloured spots or short bars either side of the vertebral line : these spots or bars are partly red and partly cream (longer bars may possibly indicate a juvenile female). There is a bicoloured stripe passing through the eye which comprises a thick red stripe below, and a thin white stripe above. The end of the tail is reddish brown.
In females the body is more thickset, dark above and pale yellow to white below. Numerous irregular pale yellow bands cross the body, and there is a thick dark stripe along the side of the head. The top of the head is mainly black.
This species occurs in southern Thailand, southern Vietnam, Peninsular Malaysia, Singapore and parts of Indonesia including Sumatra and adjacent smaller islands, and the Riau Archipelago.
The Bornean Keeled Pit Viper T. subannulatus, was once considered to be a form of Wagler's Pit Viper, but is now considered a separate species.

Species : Tropidolaemus wagleri

Tha Blue-necked Keelback , this attractively patterned snake occurs in lowland primary and mature secondary rainforest, with a preference for areas near forest streams and swamps. Reportedly it also inhabits waterlogged, grassy areas.
It is easily identified by the dark chevron on the nape of the neck, and by the light bluish-grey neck. The body is orange-brown to pinkish-brown with faint, oblique barring.
The head is slightly larger than the neck, and the eyes of moderate size. Body scales are strongly keeled, and the vertebral scale row is enlarged and darker in colour.
The species is terrestrial and semi-aquatic in habits, though there is a record of a juvenile found coiled on a leaf about a metre from the ground. Their prey comprises mainly frogs.
The species has been be proven to be venomous and should be treated with caution. Individuals are generally not aggressive unless provoked.
Reportedly this snake will rear up and flatten its neck in cobra-like fashion when threatened,

Family : NATRICIDAE
Species : Macropisthodon rhodomelas
Maximum Size : 75 cm
