Four-toed Sengi (Petrodromus tetradactylus) lives in open savanna across Sub-Saharan Africa. It feeds on insects and fruit. Its conservation status is Least Concern.
Fascinating facts about the Four-toed Sengi
- Four-toed sengis roam from Angola and the Democratic Republic of the Congo all the way to South Africa, Kenya and even the Zanzibar and Mafia Islands, making them the second most widespread sengi species across Africa. Their range spans subtropical dry forests, montane woodlands and moist savannas, where they hide in dense evergreen growth at night.
- Measuring just 19 to 23 cm in body length with a 15.5-17 cm tail, the four-toed sengi weighs between 160 and 280 g, placing it among the largest of its order. By contrast, other sengis range from 10 to 30 cm and weigh as little as 45 g. Their long, skinny legs hold the body 3-4 cm off the ground, giving them a spring-like gait.
- Four-toed sengis feed almost exclusively on ants, termites, crickets, spiders and other invertebrates they flick from leaf litter into their mouths, supplementing with seeds and fruit when available. In Kenya, their diet includes termites, plant matter, centipedes, ants, crickets and cockroaches, millipedes, spiders, and similar creatures. By consuming large numbers of soil-dwelling insects, they help regulate pest populations, indirectly supporting the health of nearby agricultural lands.
- Four-toed sengis can breed year-round, with gestation lasting 40-60 days and typically one or two precocial young born. The newborns weigh about 32 g and can run almost as fast as adults within hours. Mothers wean them after 15-25 days, and the juveniles reach sexual maturity at roughly 50 days.
- When a four-toed sengi darts across the forest floor, its tail points straight up and its hind feet produce a rapid rapping sound; ants hear this vibration and reply, allowing the shrew to pinpoint hidden colonies.
