Most people know that a snake sheds its skin, but does a lizard shed its skin?
A lizard is a reptile. Reptiles include snakes, lizards, crocodiles, alligators, caimans, turtles, tortoises, and terrapins. Reptiles lay soft-shelled eggs on land.
The Balkan Slow Worm (Pseudopus apodus) is also a reptile. It is not a worm and it is not a snake. It is a legless lizard. It actually has small (almost invisible), undeveloped rear legs, but it does not use its legs for locomotion. It is not a snake because it has eyelids (snakes do not have eyelids). It has a long tail. It is also known as the Pallas’s Glass Lizard, the European Glass Lizard, the Sheltopusik, or the Giant Russian Legless Lizard.

The Nose-Horned Viper (Vipera ammodytes ammodytes) is a highly venomous reptile in the Viperidae family of viper snakes. It is a viperid. It is also known as the Horned Viper and Western Sand Viper. Scientists think it might be the most dangerous snake in Europe.
The Nose-Horned Viper has a head covered with small, irregular scales that can be smooth or slightly keeled (ridged). It has 10-13 small scales around its eyes. The nasal (nose) scale is large that looks like a horn with 9-17 smaller scales along it, but it is soft and flexible.

Its back legs are thicker than its front legs. The tip of its tail has a spur (a horny, short spike).

The Geoffroy’s Side-Necked Turtle (Phrynops geoffroanus) is a freshwater aquatic reptile in the Chelidae family of long-necked turtles. It is a chelonian or a chelid. Chelonians include turtles, tortoises, and terrapins. It is also known as the Geoffroy’s Toadhead Turtle.
The Geoffroy’s Side-Necked Turtle is black to dark-grey. Its carapace (top shell) is slightly domed. Its tail and legs are grey-brown, and its plastron underbelly (bottom shell) is yellowish. Instead of its neck sticking in and out, it has a side-necked position where it places its head sideways in its shell. It has four sharp claws on its feet.
The Geoffroy’s Side-Necked Turtle does not have a hinged plastron, so it has to put its head sideways under its shell. But this means that it has a strong neck. When it is upside down, it can flick its muscular neck to right itself – to turn itself the right way up. Other terrapins and tortoises are unable to do this.

The Panther Chameleon (Furcifer pardalis) is a reptile in the Chamaeleonidae family.
The male Panther Chameleon can vary in colour from blue to red, green, orange. The female is usually tan and brown with a bit of pink or orange. It has distinctive eyes, with a pin-hole where the pupil is located. Its eyes, with good eyesight, can rotate independently, giving the Panther Chameleon 360 degrees of vision (all around it). It has a very long tongue with a suction-capped tip to catch insects.
It has five toes on each foot, but some are fused together so it looks like it only has two toes on each foot: two together and three together. Its feet act like tongs and can grip branches. Each toe has a sharp claw.

Not all snakes are venomous, but scientists at the Chinese Academy of Sciences in Chengdu wanted to know more about venomous snakes.
The researchers studied venomous Sharp-Snouted Pit Vipers (Deinagkistrodon acutus). The New Scientist magazine (22 June 2021) reported the research results.
The aggressive Sharp-Snouted Pit Viper may be able to sense how much venom it has and it won’t attack if it doesn’t have enough venom (poison).
Previous research indicates that venomous animals, including spiders, scorpions, and snakes, use their venom frugally and carefully because they do not produce a lot of venom. However, previous research did not study the possibility of whether venomous snakes save their venom for specifc situations, such as self-defence.

Most people know that bees are pollinators. Bees carry the yellow pollen from flower to flower. But not all bees are pollinators. And pollinators include other animals.
