Earthworm’s Choice PPT, Part 3: Learning Activities

Animal needs and adaptations to the environment

There are 18 independent species of penguins, which have their own unique structures. The density of penguin feathers is three to four times greater than that of birds of the same size. Their bones are hard, and their feet are relatively short and flat. Thick fat accumulation can reduce heat loss and maintain life in the low-temperature environment of Antarctica.

Goose is a genus of birds, shaped slightly like a goose, with long neck and wings, short feet and tail, lavender-brown feathers, and is good at swimming and flying. Migrate as the seasons change.

The Arctic wolf is said to be a variant of the timber wolf. It is gray-white all over, about 70 centimeters tall and weighs about 80 kilograms. Its ears are slightly rounded, and its mouth and limbs are short and stout. Change to short-haired clothing in summer and long-haired clothing in winter.

Frogs are slender and mostly good at swimming. They are cold-blooded animals and have the habit of hibernating as the temperature drops.

The frog's body color coordinates with the color of the surrounding environment and has a protective effect.

There are about 130 species of frogs in China, and almost all of them are experts at destroying pests in forests and farmland.
