This article explores the 12 main types of otters currently known, offering a comprehensive guide to this fascinating animal group.

Tipos de nutrias

1. European Otter (Lutra lutra)

Measuring 80 to 130 cm in length, this species lives near rivers and some coastal areas but always requires access to freshwater. It is found across Eurasia and northern Africa, making it the most widely distributed otter species.

Tipos de nutrias - Nutria europea (Lutra lutra)

2. North American River Otter (Lontra canadensis)

Found in North America, preferring rivers with dense vegetation. Its diet includes crabs, fish, and occasionally terrestrial mammals. Length ranges from 60 to 100 cm.

Tipos de nutrias - Nutria neártica (Lontra canadensis)

3. Giant Otter (Pteronura brasiliensis)

Native to tropical South America, it is the largest otter species, measuring 1.5 to 1.7 meters. To sustain its large body, it consumes around 3 kg of fish daily. The giant otter is endangered.

4. African Clawless Otter (Aonyx capensis)

Measuring 100 to 165 cm, it inhabits sub-Saharan wetlands and dense forests. Its diet consists of frogs, fish, and crabs.

Tipos de nutrias - Nutria africana (Aonyx capensis)

5. Asian Small-Clawed Otter (Aonyx cinereus)

The smallest otter species, ranging from 70 to 100 cm, found in India and Southeast Asia's wetlands. It faces extinction threats due to habitat loss from pollution and deforestation.

6. Sea Otter (Enhydra lutris)

Living in the cold North Pacific Ocean, it has the densest fur of any animal. It feeds on fish and crustaceans and measures between 1 and 1.5 meters. As a marine mammal, it is one of the smallest compared to huge whales.

7. South American Marine Otter or Marine Cat (Lontra felina)

The only saltwater otter in South America, found along rocky coasts and occasionally in estuaries of the South Pacific. Unlike other otters, it spends most time on land, diving only to forage. Length is 87 to 110 cm. It is poorly known and threatened by marine pollution, competition from introduced species, and fishing net bycatch.

8. Spotted-Necked Otter (Hydrictis maculicollis)

Characterized by white spots on its neck contrasting with brown fur. It is 55 to 76 cm long and lives in freshwater lakes in sub-Saharan Africa. It is near-threatened due to habitat loss and hunting.

Tipos de nutrias - Nutria de cuello moteado (Hydrictis maculicollis)

9. Neotropical Otter (Lontra longicaudis)

Ranges from Central America (Mexico) to South America (Uruguay), inhabiting various freshwater bodies like rivers, swamps, forests, and savannas that are clear and calm. It is an adaptable species feeding mainly on fish and crustaceans but also mollusks, small mammals, birds, insects, and fruit. It tolerates cooler temperatures and has been found in Andean glacial lakes.

Tipos de nutrias - Nutria neotropical (Lontra longicaudis)

10. Southern River Otter (Lontra provocax)

Despite its name, it frequents freshwater, marine, and brackish water ecosystems and also terrestrial habitats. Native to Chile and Argentina, it is threatened by extensive hunting for its fur. Medium-sized, measuring 1 to 1.3 meters.

Tipos de nutrias - Nutria sureña de río (Lontra provocax)

11. Sumatran Otter (Lutra sumatrana)

Found in Southeast Asia, once thought extinct but some populations persist. It faces ongoing threats from habitat loss. Measures 80 to 130 cm and is notable for its fur-covered nose. Often confused with the European otter due to similarity.

Tipos de nutrias - Nutria de Sumatra (Lutra sumatrana)

12. Smooth-Coated Otter (Lutrogale perspicillata)

Native to India and Southeast Asia, it has smooth, short, shiny fur and a flattened tail. It measures about 1.3 meters and is vulnerable due to pollution, habitat destruction, and hunting.

Tipos de nutrias - Nutria lisa (Lutrogale perspicillata)
