Habitat
Giant otter shrews primarily inhabit fast-flowing rivers, streams, and forested wetlands in Central Africa, including countries like Cameroon and the Democratic Republic of Congo. They prefer areas with dense riparian vegetation and rocky substrates for cover and hunting. This species avoids open waters and drier environments.
Diet
Giant otter shrews mainly eat fish, crustaceans, and aquatic insects, which they catch by diving and probing riverbeds. They are opportunistic feeders, hunting primarily at night using their sensitive whiskers to detect prey in murky waters. Feeding occurs mostly in shallow areas near the shore.
Behavior
Giant otter shrews are primarily nocturnal and solitary, spending much of their time in water hunting for food and resting in burrows along riverbanks. They are territorial, marking their areas with scent and aggressively defending them from intruders. These animals are excellent swimmers, using their webbed feet and tail for propulsion, and they communicate through vocalizations and scent marking.
Conservation Status
The IUCN lists the giant otter shrew as Vulnerable due to habitat loss from deforestation and pollution in Central African rivers. Population trends are declining, with major threats including human encroachment and water contamination.
