The other 12 otter species were recently identified by the International Union for Conservation of Nature (IUCN) as having decreasing populations, and five otter species are already on the endangered list. Among the endangered are the sea otters along the Californian to Alaskan coasts, which are threatened by "environmental pollutants and disease agents."

16 Playful Facts About Otters (3)

Otters use their dung—known as spraint—to communicate with other otters. The mammals like to keep things organized within their communities and will designate certain areas to be used as latrines. Spraint scents can vary, but often are (relatively) pleasant—one expert described them as not "dissimilar to jasmine tea." Spraint composition is unique to each otter, and the creatures can identify each other by the smells. Scientists suspect otters may even be able to determine the sex, age, and reproductive status of the spraint dropper just from a quick whiff. And since otters have superb metabolisms and can easily eat up to 15 percent of their body weight each day, there's a lot of spraint to go around.

4. OTTER MOMS ARE TOTALLY GAME FOR ADOPTION.

16 Playful Facts About Otters (4)

In 2001, a female otter at the Monterey Bay Aquarium gave birth to a stillborn pup on the same day a stranded pup was discovered in the wild nearby. The aquarium staff had previously tried raising pups themselves but found that hand-raised otters became too attached to humans to be released back into the wild. So instead, they dropped the pup in with the female otter, and she immediately went into mom mode. The aquarium has since devised a system of hand-rearing pups for the first six to eight weeks—mostly for bottle feeding purposes—before handing the pups off to female otters for raising. At six months, the pups are released back into the wild with generally strong results.

16 Playful Facts About Otters (5)

Otters can have up to one million hairs per square inch. There are two layers of fur—an undercoat and then longer hairs that we can see. The layers manage to trap air next to the otter's skin, which keeps the otters dry and warm and also helps with buoyancy. Otter pups have so much air trapped in there, they actually can’t dive under water, even if they want to.

Keeping an eye on otters in the wild is a tricky task. In the past, observers have usually set up telescopes on shore to try and monitor otters at sea. Otters won't act naturally with humans nearby, and using a telescope on a boat can get tricky in the rollicking ocean.

Once thought to be gone from the area completely, southern sea otters—known as California sea otters—have been making a comeback in recent years. But with their numbers hovering around just a few thousand, researchers have kept a close eye on the population and their studies have revealed an interesting social structure. The otters, which need to consume 25 percent to 35 percent of their body weight every day in order to maintain their metabolism and keep themselves warm in the cool waters, are divided into three "dietary guilds": Deep-diving otters that dine on abalone, urchins, and Dungeness crab; medium divers who subsist on clams, worms, and smaller shellfish; and those that stay in shallower waters, feeding on black snails.

14. A ZOOLOGIST WHO WAS STRANDED AFTER A SHIPWRECK WAS THE FIRST TO DESCRIBE SEA OTTERS.

16 Playful Facts About Otters (14)

German zoologist and botanist Georg Wilhelm Steller was the first to scientifically describe numerous new animals on the 1741 explorative voyage from Russia. Aboard the St. Peter, Steller and other 18th-century explorers crash-landed on modern-day Bering Island after getting separated from its sister ship. Over the course of a rough winter, he meticulously documented many species, and while some have since gone extinct (like a sea-cow he described that was hunted into extinction), the adorable otter was among his initial discoveries.

16. THEIR BEHAVIOR ISN'T ALWAYS ADORABLE.

16 Playful Facts About Otters (16)

Like many animals, otters sometimes behave in ways that aren't exactly within the bounds of what humans would consider morally acceptable. Even if you find them otherwise adorable, otters' mating habits will no doubt make your stomach turn.

(Video) Otter Facts Cuter Than You Think

Male otters' mating techniques are violent. They bite their female partner's face during copulation to keep her from slipping away, leaving her with substantial facial wounds. It's not uncommon for female otters to die as a result of these aggressive encounters, either through drowning or from their wounds becoming infected. Male otters have also been known to violently copulate with other species—most notably, baby seals [PDF]. The behavior doesn't stop when the seals die from the trauma. Otters have been known to guard and have sex with the bodies of their victims for up to seven days after they've died.

Scientists hypothesize that these seemingly counterproductive mating habits might be the result of a population imbalance. In California's Monterey Bay, where scientists observed otters trying to copulate with the week-old bodies of dead baby seals, there are far more male otters than females. Facing a lack of female partners, male otters may be engaging in what researchers call "misdirected sexual activity." The area in the bay where the scientists observed the most otter-on-seal mating sessions was also where there was a high population of transient male otters, ones that, unlike more dominant males, don't have an established territory filled with potential mates. In the absence of females of their own kind, then, they turned their typical sexual responses toward the seals. Nature, unfortunately, isn't always pretty.
