Extinct mammals

Mammals as a class of animals are among the most at risk of extinction. There are currently around 5400 species of mammal. Compare this with around 10000 species of birds, 30000 species of fish and 950,000 species of insects. Each mammal that goes extinct is therefore a must bigger relative loss.

Despite the relatively small number of species, mammals come in a great variety of forms. As we ourselves are mammals, we see similar traits in them. They experience grief, dreams, trauma, anger and more.

In recent years, many more mammal species have become endangered or critically endangered. Much of this is due to increased human interaction such as habitat use, pesticides and hunting. As of late 2015 / early 2016, the IUCN red list estimates 30 species of mammals as critically endangered.
