Are rhinos mammals?

Rhinos are mammals, and the rhino gestation period lasts nearly two years. Only one calf is born at a time, and a young rhino can gain 2-3 kg per day and is weaned at about two years old. They can live up to 50 years.

Do rhinos have natural enemies?

Rhinos have almost no natural enemies.

The rhino's intelligence is not very high, but its temperament is extremely irascible. It first appeared 60 million years ago and is the second-largest animal on land. It inhabits lowlands or highlands at an altitude of more than 2000 m. It is active at night, living alone or in small groups. Its living area never departs from water sources. Its diet varies by species, mainly grasses, or leaves, tender twigs, wild fruits, lichens and so on. The female's gestation period is 18-19 months. The lifespan is 30-50 years. Because of the decorative and medicinal value of rhino horn, they have been heavily poached, and all species except the white rhino are endangered. They are distributed in southern Asia, Southeast Asia and sub-Saharan Africa.

As of 2013, according to a survey by the IUCN African Rhino Specialist Group, about 20405 white rhinos were alive, making it the most numerous rhino species still existing. The white rhino is the most evolved, most intelligent and latest to appear (early Pleistocene, 2 million years ago) of the extant rhinos. Its intelligence is the highest among extant rhinos, and its brain weighs up to 360 grams.

2. Sumatran rhinoceros
