Male hippos take over limited space by claiming a small watering hole, which they make their own. They can mate with up to 10 females and exclude other males from this area. These hippos become extremely aggressive and will fight with any intruders furiously. During the end of the dry season, when more than 200 hippos can be seen at one place, maximum contention between intruder and territorial hippos is expected. Adding to this, female hippos also fend off males from approaching their offspring. Show more
