Sharks Senses
Shark Senses
Sharks depend on their senses to help them survive in their natural habitat. Therefore, most of the shark
senses are highly developed and efficient.
Lateral Line
Sharks have what is known as a lateral line. This is an internal sense that allows them to detect vibrations in
the water.
This is primary used to find their prey in the water as well as the location of other sharks that may be in the
area.
Ampullae of Lorenzini.
Sharks can also feel the electrical charge from prey in the water. The sense that can do this is called
the Ampullae of Lorenzini.
All living creatures give of some type of electricity as they move through the water. Sharks can easily detect such
movements with the Ampullae of Lorenzini.
Sharks also use this ability to help them navigate through the waters without any real effort involved.
Powerful Sense of Smell
The strongest sense for a shark is their smell. It is a common myth though that sharks can smell blood miles away
and then they will find the person or animal that it is coming from.
While sharks can smell blood, it often indicates to them that there is wounded prey they can easily overpower. It
may surprise you to learn that the nostrils on a shark aren’t used for smelling. In fact, they aren’t even attached
to their mouths.
It isn’t an instinct of killing that the blood is going to create in them. In fact, if they aren’t hungry then they
won’t even bother to look for the source of the smell. Some of the species though can smell and indicate even a
single drop of blood in the water. This is just an example of how powerful their sense of smell really is.
Research indicates that with many species of sharks, 2/3 of their brain is designed to help with the sense of
smell.
Some sharks have been seen at the surface of the water with their nose up in the air. It is believed that they
are very curious and they use that great sense of smell to detect what is going on out there. This is most likely
to happen when there has been a significant change such as pollution in the water, a tropical storm that stirs up
the waters, or even a fire that is burning in the area of the water where they live.
Good Eyesight
Sharks have good eyesight for being in the water, so they can see well during the day or the night. However, they
aren’t always able to distinguish the difference between people and other creatures that live in the water. That is
why a person on a surfboard may be bitten by a shark. They appear to be a colorful fish for the shark to consume as
a meal.
They are able to see both in clear water and in murky water though. While they may not be able to get a clear
vision of what it is, they know something is out there. It is also known that sharks are able to see in color. They
eyes may appear large at times and then smaller at others. This is because they dilate depending on the amount of
light that is available at any given time.
Some species of sharks have protective coverings for their eyes. They will use them when they are being attacked
or when they are attacking prey. This is an instinct reaction that helps to ensure their site isn’t hindered during
the process.
Also Good Hearing
It is believed that sharks can also hear extremely well. Some of the species have the ability to hear prey for
miles from where they happen to be. They have openings on the sides of their heads that lead to the inner ear. They
can hear sounds at an extremely low frequency from a long distance.
You may find it interesting to learn the taste buds of a shark aren’t found on their tongue. Instead they are
all over the inside of their mouths. Due to the keen senses that sharks have, they usually don’t have any problems
finding their prey. They are very intelligent too so they know what they must do in order to survive.
