description Thick-tailed opossum Overview

The thick-tailed opossum, formally known as Lutreolina crassicaudata, is a semi-aquatic marsupial native to South America. It is adapted to life in aquatic environments such as wetlands and tropical rainforests, characterized by its otter-like build, webbed feet, and heavily furred tail used for navigation. Unlike many other opossum species, it is primarily nocturnal and carnivorous, feeding on aquatic prey, insects, and small vertebrates. Wildlife biologists study this distinct species to understand the adaptive evolution of New World marsupials.
