Neotropical Otter — facts, diet, habitat & conservation

Ranging from tropical Mexican rivers all the way south toward the cool edges of Patagonia, a neotropical otter covers more geographic ground than any other otter species in the Americas, adapting its lifestyle to rainforest, coastline, and temperate river alike.

Overview

The neotropical otter, Lontra longicaudis, is a Near Threatened mammal native to wetland, ocean, coastal, and rainforest habitat from Mexico south through most of South America. Its exceptionally broad geographic range, its adaptability across dramatically different habitat types, and its long, tapering tail make it one of the more widely distributed otter species found anywhere in the world.

An otter built for almost anywhere

While many otter species specialise narrowly in either fresh water or the sea, the neotropical otter instead thrives across an enormous range of conditions, from steamy tropical rainforest rivers to the cooler temperate waters approaching Patagonia.

Status

Near Threatened, remaining widespread across an enormous range, though hunting and habitat degradation have driven declines in parts of this range.

Neotropical Otter: common questions

How does the neotropical otter's range compare with other otters?

This species has the broadest geographic range of any otter species in the Americas, found from tropical rivers in Mexico south into cooler waters approaching northern Patagonia.

Why does the neotropical otter have an alternative name?

This species is also known as the long-tailed otter, a name reflecting its unusually long, tapering tail compared with some other otter species.

Can the neotropical otter live in different types of habitat?

Yes, this species is highly adaptable, found in tropical rainforest rivers, coastal mangroves, and cooler temperate rivers across its enormous range spanning much of the Americas.

Is the neotropical otter a social animal?

Not especially, this species is largely solitary outside of breeding and raising young, unlike some more social otter species found elsewhere in the world.
