Otters hold hands while sleeping: Sea otters often hold hands or wrap themselves in kelp while resting on the water. This keeps them from drifting away from their group while they nap. It’s called rafting and yes, it’s as adorable as it sounds. (Source: Photo by wikimedia commons)

They carry a favourite rock: Otters are one of the few animals known to use tools. Many keep a special rock tucked into a loose pouch under their arm, using it again and again to crack open shellfish. A built in pocket and a favourite tool? Pretty clever. (Source: Photo by wikimedia commons)

Otters can teach each other tricks: These intelligent animals learn by watching and copying one another. Young otters often pick up hunting methods, tool use and survival skills from older members of the group, making them quick learners in the wild. (Source: Photo by wikimedia commons)

Their fur is the densest in the animal kingdom: Otters don’t rely on blubber like seals. Instead, they stay warm with incredibly dense fur, up to a million hairs per square inch. That thick coat traps air and keeps icy water from reaching their skin. (Source: Photo by wikimedia commons)

They are playful for a reason: Otters love sliding down muddy banks, tossing pebbles and chasing each other through the water, but it’s not just for fun. Play helps sharpen hunting skills, improve coordination and build social bonds. (Source: Photo by wikimedia commons)

They help protect ecosystems: Otters play a huge role in keeping rivers, wetlands and coastal habitats balanced. Sea otters, for example, eat sea urchins that can destroy kelp forests. Their presence helps entire ecosystems thrive. (Source: Photo by wikimedia commons)
