Spotted-Necked Otter

The spotted-necked otter (Hydrictis maculicollis), also called the speckle-throated otter and known locally as the "water hyena", is the smallest of Africa's otters. It has a sleek chocolate-to-reddish-brown body, a white chin and upper lip, and creamy blotches scattered over its throat and chest, which give it its name. Unlike the clawless otter, it has fully webbed feet with sharp claws, making it a superb swimmer and diver. It hunts mainly fish by day in clear water, and is noisy and sociable, chattering and whistling to its companions. It is listed as Near Threatened.

Quick answer: The spotted-necked otter lives in clear lakes and larger rivers across much of sub-Saharan Africa. Lake Victoria holds some of its largest populations, including on Tanzania's Rubondo Island. In Kenya, look for it along the clear, rocky shores and islands of Lake Victoria, near Ruma National Park, and in some western Kenya rivers. Sightings are never guaranteed.

What Does a Spotted-Necked Otter Look Like?

The spotted-necked otter has a long, slim, streamlined body, a long tapering tail and a small, flattened head. Its fur is chocolate to reddish-brown, with two layers: dense underfur that traps air for warmth, and longer outer guard hairs. The chin and upper lip are white, and the throat and chest are marked with creamy or white blotches. The pattern varies so much that individuals can be told apart by their spots.

All four feet are fully webbed and have well-developed claws. On land the otter moves rather clumsily, but in water it is fast and agile.

Spotted-Necked Otter vs Cape Clawless Otter

Kenya has two otter species, and they sometimes share the same lakes.

• Spotted-necked otter: smaller and slimmer, with cream blotches on the throat and fully webbed, clawed feet. It eats mainly fish and needs clear water.
• Cape (African) clawless otter: much larger and heavier, with a plain white chin and throat and clawless, unwebbed front paws. It eats mainly crabs and copes with murkier water.
• Where they meet: both live around Lake Victoria, where they can coexist because they eat different food.

Where Do Spotted-Necked Otters Live?

Spotted-necked otters live in lakes and larger rivers across much of sub-Saharan Africa south of about 10°N. They are common in Lake Victoria and Lake Tanganyika, and across Zambia, but are absent from the Zambezi below Victoria Falls. They never enter salt water. Because they hunt by sight, they need clear, unpolluted water with plenty of fish, and they seldom move more than about 10 m from the water's edge.

In Kenya, they are found mainly around Lake Victoria and in some rivers in the west of the country. Browse our wildlife guide and Great Lakes of Kenya to see where these habitats are found.

What Do Spotted-Necked Otters Eat?

Fish dominate the diet, especially small cichlids such as Haplochromis in Lake Victoria. According to San Diego Zoo Wildlife Alliance, they also eat crabs, frogs, insect larvae and water snails where fish are scarce. They often catch fish among rocks and sticks rather than in open water, and they eat small prey while floating on their backs. In Lake Victoria they have been seen catching fish as large as themselves.

Spotted-Necked Otter Behaviour

Spotted-necked otters are active by day, especially in the early morning and late afternoon. They can be solitary, but often live in groups, sometimes in same-sex groups for much of the year.

Group Fishing

Groups sometimes work together to herd shoals of fish, though each otter catches and eats its own prey.

Chattering and Whistling

This is a very vocal otter, using high whistles, rapid shrill chatters and grunts to stay in touch with its group.

Dens and Holts

They rest in holes among rocks, under tree roots or in dense reeds near the water.

Predators

Known predators include Nile crocodiles, lions and African fish eagles.

Breeding

After a pregnancy of about two months, the female gives birth to one to three cubs in a den. The cubs stay with their mother for about a year.

Is the Spotted-Necked Otter Endangered?

It is listed as Near Threatened on the IUCN Red List, and its population is decreasing. Because it needs clear, fish-rich water, it is especially sensitive to pollution, siltation from deforestation and farming, and the loss of lakeshore vegetation. Many otters drown after getting tangled in nylon fishing nets, and some are killed by fishermen who see them as competitors or are hunted for their skins and for traditional uses. In Lake Victoria, the introduction of Nile perch and the decline of native cichlids changed the food available to otters. Because they sit at the top of the aquatic food chain, they can also build up harmful chemicals from polluted water.

Conservation work is making a difference. The International Otter Survival Fund reports that, in Kenya, it helped local people set up tilapia fish farms to provide food for both people and otters and reduce conflict. The IUCN Otter Specialist Group also supports research across Africa. You can explore recorded sightings on iNaturalist.

Where to See Spotted-Necked Otters in Kenya and East Africa

Spotted-necked otters are active by day, but they are shy and live mainly in quieter parts of Lake Victoria and clear rivers. A boat trip along rocky shores and islands gives the best chance.

Where to Look

• Lake Victoria, Kenya: rocky shorelines, islands and quiet bays along the Kenyan shore, around Homa Bay and Mbita. Combine a lake visit with nearby Ruma National Park, home to roan antelope and oribi.
• Western Kenya: clear streams and rivers around Kakamega Forest and the highlands.
• Rubondo Island, Tanzania: an island national park in Lake Victoria, one of the best places in Africa to watch spotted-necked otters. Ask about our multi-country safaris.

Take a Boat Trip

A quiet boat ride along rocky shores in the early morning or late afternoon gives the best chance of seeing otters fishing, surfacing with prey and chattering to each other.

Scan Rocky Shorelines

Look for heads breaking the surface near rocks and reeds, and for otters resting on rocks at the water's edge.

Build a Western Kenya Route

Combine Lake Victoria, Ruma, Kakamega and Saiwa Swamp on a tailor-made trip through our Kenya safaris.

Travel in the Dry Season

Clearer water and calmer conditions make otters easier to spot. In western Kenya, the drier months are generally December to February and June to September. Travelling in the wet months instead? Read Can I do a Kenya safari during the rainy season?

Responsible Wildlife Viewing

Keep boats at a respectful distance and cut the engine when otters are near. Never chase or surround them. Don't leave fishing line or nets in the water, as otters easily get tangled and drown. Support local fishing communities and lodges that protect lakeshores and clean water.
