Underwater, Antarctica's Weddell seals are fast-moving, graceful predators, catching and eating as much as 100 pounds of food per day. They dine on squids and fish and have been known to enjoy the occasional penguin or two.
On land, they are hilariously ineffectual blobs of jelly.
You can see that dichotomy in action in this great (and long) video made by Henry Kaiser in Antarctica. Following the adventures of a baby seal on the ice and under the water, the video is peaceful, meditative and reminds me a bit of the sort of old-school Sesame Street video that would build simple, kid-friendly narratives out of nature footage and music. (The music, by the way, was written and performed by Henry Kaiser, as well.)
Despite their poor performance in land-based locomotion, Weddell seals actually live on the ice, descending into the water to hunt and mate and swim around. They use natural holes in the ice to get from above to below and back, but they also work to maintain those holes and often use their teeth to chew at the edge of the ice and make a small hole larger. At about 13 minutes into the video, you can watch a seal doing just that — rubbing its head back and forth to enlarge an opening in the ice.
And why hang out on the ice, to begin with? Simple. In the water, seals are, themselves, potential dinners for larger creatures. On land, they have no natural predators at all and can safely bask in the sun, lying on their cute and chubby bellies for so long that their body heat hollows out divots in the ice.
Watch it eat. ERMAHGERD. It's almost enough to make you forget about the horrors of the echidna penis. Almost. Until you notice that the puggle has five legs. So, there's that.
It's not just adorable! Grooming is actually an incredibly important part of keeping this baby sea otter healthy. Joanne Manaster visited the Shedd Aquarium in Chicago and came back with a whole post for the PsiVid blog about the science of cute baby animals.
When an otter is raised by humans, there are many skills they need to learn, including how to feed themselves, groom themselves, and to sleep in the water. Unfortunately, once they are habituated to humans, they will not gain the skills needed to hunt, so cannot be released into the wild. On the other hand, the otter raised by the surrogate will gain all necessary skills and may be released to the wild in the future.
That's why Toola—the world's most influential otter—was so important. Those habits, including grooming, are a big deal in the wild.
From Shedd’s website: “Keeping the pup’s thick fur clean, dry and fluffed is essential to her survival. Sea otters are the only marine mammals that aren’t wrapped in an insulating blanket of blubber. Instead, they have about 1 million hairs per square inch of skin, divided into an outer layer of thick guard hairs and an inner layer of dense, wooly underfur honeycombed with millions of tiny air pockets. The layers work together to keep water out and body heat in. If the fur becomes matted or fouled with pollutants such as oil, cold sea water penetrates to the otter’s skin and the animal can quickly succumb to hypothermia. Otters shed their fur gradually and throughout the year so that they are never without this vital protection.”
