Is Hippo Important?

Even though it’s not apparent, every animal provides some benefits to nature. Hippos play a vital role in Africa’s aquatic ecosystem. They throw mud at others to communicate superiority among themselves.

In turn, Hippos provide 60,000 kilograms of dung annually into the river. Some river fish need dung in their diet. The wastage of hippopotami also diffuses vast amounts of nutrients and energy in the wildlife system.

The Message of World Hippo Day

The population of hippos is in critical numbers now. They are at constant risk as humans kill them for several reasons, including for food, ivory tusk, making luxury items of their skin and teeth, and even lowering human-wildlife conflict.

River horses also suffer from habitat loss resulting from settlements, infrastructure building of roads, and increasing agricultural production sites.

Consequently, the home of these mammals are being destroyed and their means of survival. Hippos are susceptible to extinction for all these reasons, with about 115,000 to 130,000 remaining. Hence, this day aims to raise awareness of threatened hippo species.


World hippo day resembles the need for hippos in the world and works towards impacting their betterment. We all should observe this special day with passion and spread the message of its importance to others. Hopefully, with our integrated effort, we will be able to make the world a better place for our endangered animals.
