To prevent themselves from floating away in the swirling sea while they sleep, sea otters often entangle themselves in forests of kelp or giant seaweed to provide anchorage. This is also the reason why they hold hands. They do so in order to prevent themselves from drifting away from the group.
How long can a sea otter live?

Activity Cycles. River otters may be either diurnal or nocturnal; most are generally more active at night. Clawless otters are mainly nocturnal, though some individuals may be active during the day in remote areas that are free of human disturbance. Sea otters are generally diurnal.
Otters are frequently described as “ferrets on crack,” and for good reason. From a legal standpoint, owning an otter can be trickier than a skunk, but it is possible. They love water so it is best if you have a body of water nearby for them to frolic in. You'll also need access to plenty of fish.
Sea otters spend approximately 9 to 12 hours foraging each day. On average, an adult male California sea otter consumes over 4,000 calories daily. Sea otters eat many kinds of invertebrates, including sea urchins, abalone, clams, crabs, snails, sea stars, squid & octopuses.
The sea otter can live its entire life without leaving the water. Another underwater superlative: The sea otter is the only marine mammal capable of flipping over boulders on the sea floor—in this case to search out food. And the only marine mammal to catch fish with its forepaws and not its mouth. 6.
Learn More About Sea OttersLike other members of this family, they have very thick fur. In fact, at 850,000 to 1 million hairs per square inch, sea otters have the thickest fur of any mammal.
They've long been lauded as one of the world's most intelligent animals. But new research suggests that sea otters may have outsmarted them — at least in the handiness department. That's well before other sea animals learned to MacGyver their surroundings.
Sea otters are the exception, giving birth in the water. Baby otters, called pups or kittens, stay with their mothers until they're up to a year old, or until she has another litter.
Otters rarely attack humans, but can sometimes be territorial, especially when they are protecting their babies.
Other species may do more killing. But few species are violent in quite as disturbing a way as the otter. For one thing, sea otters murder other animals even when they don't get food out of it, just for fun or something. At 105 min into the encounter, the sea otter released the pup, now dead, and began grooming.
Dolphins, rats, pigs, elephants, dogs and even crows have long been heralded as some of the world's most intelligent animals, but it turns out otters deserve some credit, too. But tool usage in otters makes them one of the few mammals, other than primates, who have shown the ability to do so.
To put it simply, they stink. They produce a strong, disagreeable scent from their anal glands and they have especially smelly poop, perhaps from a diet of fish, crab and other sea creatures. He spent last Saturday cleaning otter feces off the docks, which he considers just a normal part of maintaining the marina.
Otters may also occasionally prey on birds, rabbits, and rodents. Giant otters eat mainly fishes and crabs.
In the Arctic, killer whales often dine on sea otters, while in the Californian coast, great white sharks consume many otters each year. Other predators include sea lions in certain areas, as well as eagles, which eat otter pups. On land, coyotes and bobcats also predate on otters.
First, sea otters are two to three times the size of river otters—and, when at the water's surface, they float on their backs, while river otters swim belly down like most animals. Next, the tail of a sea otter is short and flattened; a river otter's tail is long and pointed.

They can grow to be more than a meter long, from head to tail, and weight up to 14 kg.
Eyesight. Eyesight is probably the most important sense for hunting. Vision studies conducted on Asian small-clawed otters suggest that, in bright light, visual resolution is equally good in water and air; in dim light, resolution is better in air than in water.
Otters boast a sharp set of canines and crushing molars. And theirs is a formidable bite, roughly comparable in force to a German shepherd's, which can break hand bones but mostly punctures or bruises skin. Yet even bites are rare.
How does the otter actually kill the gator? It doesn't, not directly. First, that's a pretty hard animal to bite through. The armor on the back is made to deflect bites from other alligators, so it's very tough.
Rabies and River OttersRiver otters can contract the rabies virus when they are attacked by a rabid predator or by another otter who contracted the disease and become aggressive as a result. River otters have been documented as both having rabies and spreading rabies in the United States.
Male sea otters sometimes attack baby seals and attempt to mate with them, writes Brian Switek for Slate. These assaults often result in fatal injuries to the seal pups, he writes–and otters are similiarly rough with female sea otters.
But otters are very territorial and will attack other animals to protect their stomping grounds, especially in the spring when they give birth. "Otter attacks are rare but they do occur," he said. He said he recently received a call to remove an otter that kept charging at a dog.

Yes, definitely otters will hurt, mame, and even kill your ducks.
An example of a zoonotic disease that most people are familiar with is rabies. Rabies has never been reported from sea otters, but they are certainly susceptible to this virus, and rabies cases have been reported from river otters.
