The water opossum (Chironectes minimus) is also known as yapok. The species got this name from the river Oyapok in French Guiana.
These aquatic marsupials are thought to be native to French Guinea on the coast of South America and are found in Central and South America. They are found in their natural range of tropical moist forests and near streams in Argentina, Brazil, Venezuela, Ecuador, Paraguay, and Mexico.
Water opossums are mammals but belong to a subfamily Didelphinae of marsupials, meaning animals with a pouch for raising their young ones. Water opossums are the only aquatic marsupials belonging to the family Didelphidae, species C. minimus. Another distinctive feature about these aquatic species of animals is both sexes have a pouch to house their offspring.
Along with preying on fish and crustaceans, these animals also feed on some aquatic plants. Water opossums have short, thick, water-repellent fur with a gray and black marbled pattern. The forefeet and the broad hind feet are different.
The hind webbed feet are used for swimming through water in aquatic habitats and moving ahead with alternate strokes. Water opossums are mammals and marsupials that live in aquatic habitats. They have adaptations that allow them to protect young animals while swimming.

Their water-repellent coats help the C. minimus survive and nurture their young ones. Marsupials are found in Australia as earlier, there was a lack of predators and competition. Mothers could develop babies in pouches.
What is a water opossum's habitat?
The ideal habitat of water opossum yapok are areas near the rivers and lakes. They live in the warm tropical climate and subtropical rainforests in South America and Central America. Yapoks are usually found in altitudes from sea level to 6000 ft (1829 m) above in their range. Yapoks lead a sedentary lifestyle with no migratory habits.
The lifestyle and habitat of this semi-aquatic, web-footed species are different from other Didelphidae family members.
These animals are outstanding divers and swimmers. They swim along the length of rivers with the help of their webbed hind feet.
The symmetrical hind feet distribute the force of the swimming strokes equally. Owing to this adaptation feature, water opossum yapoks can move quickly through any aquatic surrounding. When threatened, yapoks jump into the water to escape from predators.
Who do water opossums live with?
Water opossum yapok leads a solitary life except for breeding season. Water opossums are hostile toward other yapoks of their species and forage and hunt for prey alone in freshwater bodies in their range. These mammals use their prehensile tails to hold and transport nesting materials.
How long does a water opossum live?
A yapok’s lifespan in captivity is about three years.
How do they reproduce?
Water opossums are polyestrous and come into heat and can mate more than once a year. A pair stays together for days and as a mating ritual, the male follows circles the female. Reproduction takes place twice a year.
Average two or three offspring per breeding season are born. The male or the jack yapok leaves after mating.
The gestation period lasts for about twelve days. Jills, or females, take care of the offspring. Females can give birth to up to twenty jellybean-sized joeys at a time but only a few reach the mother’s pouch alive.
The young ones develop and stay safe inside the mother’s pouch even when she is swimming. Young yapoks grow the fastest among all the Didelphidae species animals. The young animals spend about forty days inside the mother’s pouch.
By then their body fur, markings, and pigmentation are visible and they open their eyes. After a while, they leave the pouch but suckle and live with their mother. Sometimes the females carry their young on their back.
Reproduction happens at different times in different countries. In Brazil, they reproduce from December till February. January and February are the ideal birth months.
What is their conservation status?
The conservation status of water opossums is of the Least Concern according to the IUCN.
