The common large kangaroo is called the red kangaroo, which is also the most famous one. Its image is widely known by people all over the world. Look at its unruly temperament, sparse stubble, and strong chest. Its muscles are coiled and its veins are exposed. It looks very social at first glance.
They are good at jumping, can jump 7-8 meters away, 1.5-1.8 meters high. If they go to the Olympics, they will definitely win the "double jump championship". Kangaroos like to form "small groups", often living in small groups in grassland areas, jumping around at night to forage for various grasses, wild vegetables, etc.
Red kangaroos are usually quiet and docile, but they will use their hind feet to kick people when they have no way out. Their hind feet are so powerful that they can kill people in one go. When males fight to win, their movements are like boxing.
Kangaroos cannot tolerate others challenging their authority, especially strong male kangaroos. They don't even allow other kangaroos to look directly into their eyes, because this behavior is a symbol of provocation in their eyes. Once other kangaroos do this, they will inevitably be attacked.
In the zoo, many senior kangaroo keepers know this knowledge, and try to avoid eye contact with kangaroos at work, otherwise they will be attacked mercilessly.
Kangaroo: Look at me, you little one!
