Tierslang ( Afrikaans )

provided by wikipedia AF

Die tierslang (Telescopus semiannulatus) is 'n slang wat voorkom in die noorde van Suidelike Afrika en verder noordwaarts tot in sentrale Afrika. Daar is twee tierslange: Beetz se Tierslang wat van die Wes-Kaap tot die Noord-Kaap en Namibië voorkom. Die Damaratierslang (T. s. polystictus)'n sub-spesie en kom van die noorde van die Noord-Kaap tot in Namibië voor. Dit mag 'n aparte spesie wees. In Engels staan dit bekend as die Eastern tiger snake.

By die slang is die kop onderskeibaar van die lyf. Die oë is groot met vertikale pupille. Die rug van die slang is oranjepienk tot dof salmpienk of oranjebruin met 22- 75 donkerbruin tot swart dwarsbande of saalagtige vlekke op die lyf en stert. Die pens is gelerig tot oranjepienk.

Die slang kom voor in 'n verskeidenheid habitats, hoofsaaklik klipperige dele van woestyne, Karoosstruikveld, dorre en vogtige savanne en laaglandwoude. Dit is stadig en is snags aktief; in die dag skuil dit onder stukke plat klip, in klipskeure of onder boombas. Dit is hoofsaaklik 'n grondslang maar waag dit dikwels in bome, struike en ou geboue om kos te soek. Na somerreën seil dit dikwels oor teerpaaie en word baie doodgery. Soos die rooilipslang maak dit 'n indrukwekkende vertoning wanneer hy bedreig of vasgekeer word deur sy kop van die grond te lig en met die lippe oopgesper, aggressief te pik.

In Namibië kan dit verwar word met die koraalslang, skildneuskobra of die sebraslang. Die tierslang se vyande is anders slange en klein karnivore. Hulle vreet hoofsaaklik akkedisse, veral geitjies, jong voëltjies, vlermuise en knaagdiertjies.

Die slang is ovipaar en lê 3 tot 20 eiers in die somer. Die kleintjies is 17 tot 23 cm lank wanneer hulle uitbroei. Die slang se gif word nie as skadelik beskou nie en hou geen gevaar vir die mens in nie.

Telescopus semiannulatus

provided by wikipedia EN

Telescopus semiannulatus, commonly known as the common tiger snake, tiger cat snake, or eastern tiger snake is a species of rear-fanged colubrid snake. It is widespread in central, eastern, and southern Africa.[2]

Geographic range

Range by UN subregion:[2]

Description

Adults average 60–90 cm (2.0–3.0 ft) in total length, with 17–21 rows of dorsal scales. The tiger snake is one of the more colorful species of snake in the family Colubridae. The upper side is pale orange to salmon pink in color with 24–48 black or dark-brown cross bars or blotches along the back and tail; the underside is pale yellow to orangish pink along the throat, paler along the rest of the body. It has a distinct head and large orange eyes with vertical pupils, and a narrow body with long tail.

Subspecies

There are two subspecies:[2]

  • Telescopus semiannulatus polystictus Mertens, 1954
  • Telescopus semiannulatus semiannulatus Smith, 1849

The subspecies T. s. polystictus, Damara tiger snake, is found in the highveld of Namibia and northwest South Africa,[2] has a more mottled appearance and more black bands (up to 75), and may be a separate species.

Habitat and behaviour

Telescopus semiannulatus is found in both dry and humid subtropical and tropical habitats, from rocky desert, scrub and savanna, to lowland forest. Largely terrestrial but sometimes arboreal, it shelters under bark and rock or in thatched roofs. It is a nocturnal snake.

Venom

Telescopus semiannulatus is rear-fanged and mildly venomous, but not dangerous to humans. Localized swelling might occur. Because Telescopus semiannulatus feeds mostly on lizards, the venom is more effective on other reptiles.

The fangs are grooved rather than hollow. When Telescopus semiannulatus grabs onto its prey, it holds on and chews venom into the wound, adding constriction to immobilize prey.

Diet

Its diet is largely lizards, especially geckos, but also small rodents and fledgling birds and bats.

Captivity

Initially T. semiannulatus strikes readily, but the venom is not dangerous to humans, and it tames quickly. In captivity it accepts geckos while larger individuals will take half-grown mice. Even smaller animals are eating fresh born mice. In captivity it gets really calm and is interested in the things that happen around.

Breeding

The tiger snake is oviparous.[2] Females lay half a dozen to several dozen eggs in damp leaf litter.
