The authors found low, but significant, genetic differentiation among H. Three species of hippopotamus, the European hippopotamus (Hippopotamus antiquus), Hippopotamus major and Hippopotamus gorgops, ranged throughout continental Europe and the British Isles.

All three species became extinct before the last glaciation.

The genitals of the female are unusual in that the vagina is ridged and two large diverticula protrude from the vulval vestibule. Hippopotamus teeth sharpen themselves as they grind together.

Genetic analyses have tested the existence of three of these putative subspecies. Three species of Malagasy hippopotamus became extinct during the Holocene on Madagascar, one of them within the past 1,000 years.

A study examining mitochondrial DNA from skin biopsies taken from 13 sampling locations, considered genetic diversity and structure among hippo populations across the continent. The Malagasy hippos were smaller than the modern hippopotamus, likely through the process of insular dwarfism.

The lower canines and lower incisors are enlarged, especially in males, and grow continuously.

The incisors can reach 40 cm (1 ft 4 in), while the canines reach up to 50 cm (1 ft 8 in).
