\n\nLiving in a group helps the giant otter survive. A typical family has between three and eight members. The group is led by a dominant breeding pair. These families are very cohesive, which means they stick close together. They work together to protect their territory and find food.

Their fur is very short but extremely dense. This thick fur keeps water away from their skin. They have special whiskers called vibrissae. These whiskers help them feel changes in water pressure. This helps them find prey like catfish and characins.

They can even close their ears and nose while swimming.\n\nScientists have studied these otters for a long time. Biologist Nicole Duplaix did important work on them in the late 1970s.

Early explorers in the 19th century even called them \"river wolves.\" In Brazil, people call them ariranha. The scientific name, Pteronura, comes from Greek words meaning \"wing-tail.\" This describes their unique tail shape. Fossils show that ancestors of these otters lived a long time ago. Some fossils were even found in a cave in the Brazilian Mato Grosso.\n\nToday, the giant otter faces many hard jobs. They are listed as an endangered species. This means there are not many left in the wild. There are likely fewer than 5,000 giant otters remaining.

In the 1950s and 1960s, people hunted them for their soft fur. Now, the biggest threat is habitat loss. This happens when their homes in the rivers are destroyed. The Guianas are one of the last places where they are safe. Protecting their rivers is the best way to help them.",
