Is the sheltopusik venomous, and how is it different from a snake?

Snakes are creatures we know very well; they look frightening, are soft, and most are venomous. There is also a creature very similar to a snake; it is not a snake, yet it looks so much like one that it can almost pass for the real thing. This is the glass lizard. So, is the sheltopusik venomous? How is it different from a snake?

1. Is the sheltopusik venomous?

The sheltopusik is not venomous. Common species of glass lizards include the Chinese glass lizard, the slender glass lizard, the Oriental glass lizard, and the sheltopusik. In fact, all glass lizards are non-venomous. They often live in loose-textured, not-too-humid farmland and its surroundings, usually hiding in burrows or soft soil. They mostly come out on sunny days to forage for earthworms, slugs, or beetle larvae.

The sheltopusik is native to the northern Caucasus, a small part of Asia, the Middle East, and the central Asian regions of the former Soviet Union. It lives and shelters under the leaf litter on the forest floor. It is carnivorous and feeds on invertebrates; zoos feed it crickets and pinky mice. In the Balkans of Europe, there is a separate population on the Crimean Peninsula and along the Black Sea coast of the Caucasus.

The glass lizard is commonly known as the earth dragon or golden snake, and its scientific name alone is awkward: is it a snake or a lizard? Biologists tell us: a glass lizard is a glass lizard, neither a snake nor a lizard. It is a creature of the phylum Vertebrata, class Anelytropsidea. Friends with some understanding of biological classification should know that class is a relatively high-ranking category, such as Mammalia or Aves, so Anelytropsidea is a very large group of organisms.

Nevertheless, the classifications under this class Anelytropsidea are mainly distributed in the Americas, and in our country only two species of glass lizards are distributed——the Chinese glass lizard and the slender glass lizard, and they are mainly distributed in Jiangnan and Taiwan, China.

At first glance, a glass lizard looks almost exactly like a snake. Even up close, or even handling it carefully, a layperson still cannot tell the difference between a glass lizard and a snake.

2. How is the sheltopusik different from a snake?

1. Glass lizards have closable eyelids, while snakes do not.

2. Glass lizards have external ear openings; snakes do not.

3. More than two-thirds of a glass lizard's body length is tail; a snake's tail is shorter than its body.

4. A glass lizard's tail breaks off easily on its own; a snake will not shed its tail by itself.

5. A glass lizard's body is covered with hard, square scales arranged in rings, and the belly scales are small and in multiple rows; a snake's belly scales are large and in a single row, with vestigial hind limbs on both sides of the cloacal opening.

The body size of glass lizards varies quite a bit depending on the species. The smallest, the worm lizard, is only as big as an earthworm; larger glass lizards such as the sheltopusik can reach a body length of 1-1.2 m; the largest, the brown glass lizard, can reach a body length of 1.4 m.

The above is the answer to the questions of whether the sheltopusik is venomous and how it differs from a snake. We hope it can help you.
