Representatives of reptiles in Poland

Only one species of turtle lives in Poland – European pond turtle. Its natural habitat are shallow lakes. It hunts tadpoles, snails and insects. It has dark coloration. It has got small bright spots on the underside of the shell as well as on the skin of the paws and neck. It is very skittish. Alarmed, it pulls the head and limbs into the armor.

Viviparous lizard is the smallest Polish lizard. It can be found throughout the country. Especially often occurs in the mountains and foothills. It feeds on insects, slugs, earthworms and spiders. Attacked by a predator, it can discard its tail that moves rapidly for a few minutes, which distracts the attacker's attention and creates the opportunity for the lizard to escape. After some time, the lost tail grows back.

Common European adder is the only poisonous snake occurring in Poland. It lives in the forest edges, glades, neglected gardens, dry mountain meadows. It can often be seen to be basking in the sun. It is not aggressive. It attacks only when it feels threatened and its venom is not lethal. It feeds mainly on small mammals, frogs, eats bird chicks and insects. It has a broad, heart‑shaped head and a stocky body structure. Unlike other snakes, its pupils are vertical. Most adders have got a zigzag pattern on their back, the so‑called cain ribbon.

The grass snake is most often found near water basins, where it hunts amphibians and their larvae. It is a great swimmer. It can be easily distinguished from the Common European adder because it has got yellow, crescentspots on both sides of its head.

Task 1

Before watching the „Portraits of our reptiles” picture gallery, write down the research question and the hypothesis. When watching the picture gallery, write down your observations and finally, conclusions.

Task 2

Explain why there are more species of reptiles in the south of Poland than in the north.

Reptiles, similarly to amphibians, are perceived by humans as useful animals. They regulate the numbers of insects, snails and small vertebrates, especially rodents that are pests to forests and fields. In addition, they constitute food for other vertebrate animals, mainly birds and mammals.

Task 3

Some people eradicate snakes and similar to them blindworms. Formulate arguments that this behaviour is inappropriate in both ethical and biological terms. Use scientific grounds.
