Karoo Round-eared Sengi

The round-eared sengi or round-eared elephant shrew (Macroscelides proboscideus), also called the Karoo round-eared sengi or Karoo round-eared sengi to distinguish it from its sister species, is a species of small mammal belonging to the sengi family (Macroscelididae), and distantly (ancestrally) related to elephants. It is found in Botswana, Namibia, and South Africa. Its natural habitats are subtropical or tropical dry shrubland, and grassland, and hot deserts. They eat insects, shoots, and roots. Their gestation period is 56 days. The species was formerly misleadingly called the short-eared sengi or short-eared elephant shrew.

Sengis are among only a handful of monogamous mammals, making them a model group for the study of monogamy. They have been studied for their mate guarding behavior. Mate guarding is considered a predominant male trait in round-eared sengis. This strategy is used to guard the female before and after heat to eliminate male competition, which makes male round-eared sengis monogamous and more vulnerable to their surroundings as they spent a majority of their time dedicated to this tactic.
