Sea Otters
Sea otters are the smallest marine mammals and are adapted to spending almost all of their
lives in the ocean. Although they resemble small seals, sea otters are not actually related to
seals, but rather to weasels, badgers and minks. They belong to the species „Enhydria lutris“,
from the Greek „en hydra“, meaning „in the water“, and the Latin „lutris“, meaning otter.
Sea otters can be found in the Pacific Ocean along the coast of California, up to Alaska,
along the east coast of Russia, and all the way up to the northern tip of Japan. They prefer
coastal waters and only swim out into the deep ocean when travelling between islands and
the mainland.
Unlike other marine mammals such as seals and dolphins, sea otters do not rely on a layer of
fat to insulate their bodies from the cold water. Instead, sea otters depend on their fur to
keep warm. But even with a thick fur coat, the sea otter has to work hard to keep warm,
spending hours each day grooming its fur. Any water needs to be squeezed out and air needs
to be blown into the fur. The air makes the fur waterproof, ensuring that the otter‘s skin
remains warm and dry. That‘s why cleaning is essential. Dirty fur can easily get wet and
place the otter at risk of dying from the cold.
In addition to their thick coats, sea otters have another defense against the cold ocean water.
The otter has a high body temperature (around +38°C), which requires a fast metabolic rate.
As a result, sea otters need to eat a lot, sometimes as much as 25% of their body weight each
day. This is the equivalent of humans eating about 100 hamburgers!
Sea otters eat a variety of foods, including shellfish, sea urchins, fish and many different
types of invertebrate sea life. As they must constantly eat to survive, otters spend a lot of
time diving for food. Otters can dive up to 100 m for several minutes, although they prefer
shallow waters where they can make quicker dives instead.
Capturing their prey is not always an easy task. However, the sea otter is a highly intelligent
animal and perfectly capable of finding ways of capturing hard-to-get prey.
Smaller shellfish clinging to rocks can be prised off by the otter’s strong arms. The sea otter
is fairly strong, but not quite strong enough to defeat the larger abalone, which clings fiercely
to rocks. Using rocks as hammers, the otters are capable of dislodging the abalone with
several firm strikes from the side.
Underground food such as clams can be obtained by digging. Otters can dig with their
forepaws, like dogs, and sometimes use rocks as digging implements. They have a little
pouch under their left armpit in which they can store rocks or food, for example, while
swimming.
Once the otter has found its food, it carries it to the surface to eat. But not all food can be
eaten straightaway. Although sea otters have strong teeth that can bite through crab shells
and some shellfish, other sources of prey, e.g. abalones, have to be cracked open first.
Individual otters seem to have their own preferences as to which method to use to crack
open their prey.
Some otters place a big rock on their chest and then smash their prey on the rock until the
shell breaks open. Other otters reverse this operation, placing their prey on the chest and
then smashing the rock against it. Some otters use numerous short, rapid strikes, while
others administer a few strong blows.
The sea otter’s sense of tidiness can also be observed during eating. Often the otter rolls over
in the water to clear its chest of any waste scraps and avoid soiling its coat.
The curious behavior of sea otters in preparing and eating their food is a perfect illustration
of isolation and purification.
We hope you like this little story about these cute animals.
