pesutupien

Pesutupien is a term used in speculative biology and regional folklore to describe a semi-aquatic mammal-like creature that inhabits freshwater river basins in tropical parts of the Indo-Pacific. The name derives from the Indonesian word pesut, meaning otter, combined with the suffix -pien, used in some local dialects to denote species.

In fictional taxonomy, pesutupien is placed in a family close to otters, within the order Carnivora. Adults measure about 45 to 65 cm in body length, with dense waterproof fur, a long tapered tail, webbed hind feet, and a muzzle suited to catching small fish. Color ranges from dark brown to gray.

Pesutupien inhabit clear, fast-flowing rivers and downstream wetlands, often in forested catchments. They are territorial but social in family groups. Diet consists mainly of fish and crustaceans, occasionally amphibians. They are good divers and use submerged vegetation for cover.

Daily activity peaks at dawn and dusk. Reproduction yields litters of 2 to 4 pups after a gestation period of about two months, with parental care lasting several months. Young become independent after 6 to 12 months.

Because pesutupien are fictional, any discussion of their conservation status reflects imagined scenarios. In the constructed world, threats might include habitat loss from damming and pollution, with conservation emphasis on river health. In local folklore, pesutupien are mythic river guardians appearing during floods.
