Eurasian otters

Playful, strong swimmers, and expert hunters—meet the otters. These creatures are found on every continent except Antarctica and Australia. Their 13 species come in various shapes and sizes, from the sea otters found in coastal waters to the river otters frolicking in freshwater habitats. Seen in today's image is the Eurasian otter on the beautiful Isle of Mull off the west coast of Scotland. With webbed feet, streamlined shapes and dense fur coats, otters are built for speed and agility underwater. They can dive deep and hold their breath for several minutes.

From habitat loss and pollution to being hunted for their fur, these whiskered buddies are struggling to survive out in the wild. It's now important for us to raise awareness about the challenges otters face and what we can do to help protect our environment.
