#7 Sea otters

Sea otters hold hands when they sleep so they don’t drift away from each other.

While it may look like a couple of otters being adorable, it’s actually a life-saving strategy! This technique is commonly seen with mothers and their pups (that’s a baby otter!).

Another way they stay still in choppy seas is by grabbing onto long strands of kelp that grow up from the seabed.
