Elephants

1. Do you know something about elephants, penguins, koala, emu and echidna ?

2. Read these short texts and write out all dates in the table.

Elephants are big wild animals. They live in the jungle. An elephant has got large ears, a trunk and two tusks under its trunk. Elephant's trunks are very heavy. The elephant's teeth are its tusks.

Elephants have got families of 6 to 12 members. They are very clever animals.

Penguins

There are seventeen different kinds of penguins in the world. Some live near the Antarctic, others live on some islands near South America, Southern Africa, Australia and New Zealand. They all belong to the bird family. They can swim very well, but they can't fly.

The Galapagos penguin is very small. It is about 45 cm tall, and weight about 2.5 kg. Its body is black and white with black wings or flippers. On its black head there is a thin white line. Its beak is black, pink and yellow. The penguin's legs are very short.

There are now only about 1,000 pairs of Galapagos pen­guins in the world.

Koala

Koala is often mistakenly called a bear, is the fauna! emblem of Qeensland, one of the six Australia's states. It is a nocturnal tree dwelling marsupial mammal, which feeds almost exclusively on the leaves of a few species of eucalypt.

Emu

Emu is found only in Australia, is the second largest bird in the world, and probably because of its size, is flightless. Instead of flight, the Emu relies upon speed (up to 64 km per hour) and stamina for survival in its natural habitat, which is the dry plains country of the in­land. The Emu is also unusual in that although the female lays the eggs, it is the male which incubates them.

Spiny Ant-eater or Echidna

Spiny Ant-eater or Echidna is the nearest living rela­tive to the platypus, being the only other living monotreme in the world. The Echidna's natural diet is mainly ants. These little animals which inhabit open forest and rocky scrub lands, occur widely throughout the Australian Main­land, Tasmania and New Guinea.
