Animals

American robins are not shy, so they can even construct a nest near human buildings. Their nests are made of twigs, grass, mud, feathers and anything soft they can find (paper, fabric etc.).

Wolf spiders live a lonely life and are seen with other representative of their species only during mating season which occur in mid-summer.

They typically measure up to 0,5 millimeters in diameter.

While diving they can stay underwater for about 40 seconds. Between one dive and another platypuses rest above the water surface for about 20 seconds.

Females are larger and heavier than males. Moreover, female eardrums, called tympana, are roughly the same size as their eyes, while male eardrums are larger than their eyes.

After a long gestation, females give birth to living, fully developed offspring. They reproduce once a year, and birth usually up to 15 pups. Great hammerheads can birth up to 40 pups per litter.
