Having to eat 2,000 pieces of candy
might sound good, but what if you had to
make 2,000 dives to do it? Otters eat at
the surface and often eat only one thing
at a time. To eat 150 kelp crabs, the otter
needs to make at least 150 dives. And it
takes about six dives to pry just
one abalone from a rock.

SUPERSTRENGTH
Using tools such as rocks to crack
open shells is all the rage with otters in
California, but it isn’t always necessary.
That’s because sea otters are like
superheroes when it comes to
strength. Alaska sea otters crack
open dinner with their teeth! A hard
clam or mussel shell is no match for
an otter’s extremely powerful jaws
and strong teeth.
A person would have to make
several dives, use a special sharp
tool, and have lots of luck to pry a
firmly anchored abalone from its
rock. An otter has only its paws and
an occasional rock. The otter also
uses its strong paws to snatch and
overpower large crabs while avoiding
their dangerous claws.
Superswimmers, supereaters,
superdivers—sea otters definitely
deserve their rep as supertough
marine mammals.

Male northern
sea otters weigh
up to a hundred
pounds. Females
weigh up to
72 pounds.

An otter’s
tail is about
one-quarter
the length
of its body.
