Seal Feeding
What do Seals Eat?
Seals find the foods that they need in
the water around them, which is why you will only find them
where there is plenty of water. Their primary sources of food
include fish but they will consume just about any type of meat
they can get in the water. Other types of food that they enjoy
include squid, octopus, and shellfish. Sometimes food sources
are low due to the big ships fishing for such items in the same
waters as the seals hunt.
They use their flippers to get around in the water
with ease as they hunt for their prey. They are able to dive
very far into the water too when they need to in order to find
food. Some of them can dive up to 13,000 feet. They eat a great
deal of food each day so it can take them many hours to feed
each day. Generally the will consume up to 5% of their overall
body weight.
Seals don’t take the time to chew their food even though
they have sharp teeth. When they consume small enough types of
food sources they will simply swallow them. If they are after
something large they will tear it into large chunks. They have
very powerful back molars that they can depend on to easily
crush what they need to in order to make it small enough to
swallow.
Seals don’t take the time to drink water either. They are
able to get all of the water they need from the food that they
consume. When they aren’t able to find enough food their body
helps to make up for the loss. They start to break down the fat
called blubber and that produces enough water for them. This
can be dangerous though if they are losing too much fat. This
is due to the fact that this fat helps to keep their body
temperatures where it needs to be.
You will notice that seals have whiskers on their face as a
physical characteristic. These whiskers serve a purpose though
of helping them to find their prey. Even in the dark colored
waters they are able to do so because their whiskers are very
sensitive to movements and to vibrations around them. Some
people assume that seals have poor eyesight since they use
their whiskers but they see quite well. They are able to find
prey through site both during the day and at night.
Seals have very sensitive ears and they can hear their prey
very far away. The one sense they don’t use for feeding is
their sense of smell. They can move along very well in the
water when they are feeding. They usually are doing so at a
speed of about 23 miles per hour. When you see a seal moving
underwater to feed, they are more graceful than when you see
them lugging their bodies around on land.
The mothers are very caring towards their pups from the
start. They feed them gallon after gallon of milk that is ½
fat. This allows their young to grow very rapidly. They won’t
feed themselves during this time based on the behaviors of most
species of seals. When the mothers can no longer fend off their
own hunger they will go to the water to feed, leaving their pup
alone.
Instinct is what keeps these young pups alive. They grow
very rapidly from the milk their mother’s supply. They know how
to reach the water and instinctively how to swim. They are good
imitators so it doesn’t take them long at all to learn how to
hunt for their own food. This can be any time from three weeks
of age to six weeks of age depending on the species of seal
involved.
