On average, kangaroos can live from 9 to 22 years. The lifespan of a kangaroo depends on the species and whether the animal lives in the wild or in captivity. The longest living species of kangaroos is the large red kangaroo (Macropus rufus). They can grow up to 150 cm in height, and live up to 22 years, in rare cases up to 25-27 years.
The second in terms of life expectancy, as well as size, is the eastern gray kangaroo (Macropus giganteus), which can live for about 20 years in captivity and 8 to 12 years in the wild. Western gray kangaroos (Macropus fuliginosus) have a similar life span with their eastern counterparts: about 20 years in captivity and up to 10 years in the wild.
Twilight animals; Usually held in groups, are very cautious. Vegetable, but some eat worms and insects. They multiply once a year. Pregnancy is very short – 30-40 days. Give birth to 1-2 underdeveloped cubs (in giant kangaroos, the length of the cub’s body is about 3 cm) and they are hatched in a bag for 6-8 months. The first months of the cub are tightly attached to the nipple and milk is periodically injected into his mouth.
