Otters have the thickest fur of all animals with at least 250,000 hairs per square inch. Some species have up to 1 million hairs per square inch.
They are the only known marine animals that are missing the “blubber” layer of fat under the skin. Their fur retains heat instead.

Otters are the smallest of all marine mammals in the world.
An Otter can remain under water for up to 4 minutes with feeding dives up to 75m (250ft) deep.
These animals can consume up to 25% of their body weight daily. When a female is nursing she will consume even more than that. About 5 hours a day are spent in search of food.

Most species spend the majority of their time on land with one exception: the Sea Otter.
Sea otters have webbed feet, water-repellent fur to keep them dry and warm, and nostrils and ears that close in the water.
They sleep while floating on their back, often gathered in groups. Sometimes they anchor themselves in sea weeds or kelp to protect them from floating in a current.
Sea Otters are the only species that have more than one pup at a time which they also give birth to in the water. They hold infants on their chests to nurse them, and quickly teach them to swim and hunt.
Jellyfish Lake in Palau is a unique place on earth where several coincidences have made it the perfect environment for millions of jellyfish to evolve their own species – perfectly adapted and isolated from the rest of the world.

Around 12 000 years ago, as the water level was decreasing, the lake was formed as a natural basin of rocks and lime stones with only a few living creatures trapped inside it.
