marsupial
Red kangaroo (Macropus rufus). The home range of this species spans much of Australia's interior, and it is the largest member of the family Macropodidae.
The water opossum (Chironectes minimus), also known as the yapok, is the only marsupial specifically adapted to a semiaquatic lifestyle. To thrive in its environment of tropical rivers, streams, and lakes, it has developed several specialized physical traits:12
- Webbed hind feet: These facilitate efficient swimming and movement through water.12
- Dense, oily fur: This provides insulation and water resistance, helping the animal maintain its body temperature while foraging in watercourses.12
- Specialized pouch: Unlike other marsupials, the female water opossum possesses a pouch that can be tightly closed, which protects and keeps her young dry while she swims.12
These adaptations allow the water opossum to effectively hunt for its diet of fish, crabs, frogs, and shrimp within its aquatic habitat.1
