The Blue Shark is called Prionac Glauca in Latin. The Blue Shark is one of the
sharks with a nictitating membrane. These sharks have a thick skin membrane
(called nictitating mambrane) to pull down in front of their eyes just before
they attack a prey. The Blue Shark has electric sensors which lead the blue shark
the remaining distance to the prey. Blue Sharks can become up to 12,5 ft. long.
The Blue Shark is the common image people have of a shark. The Blue Sharks have
a dark blue back, light blue sides and a white belly. The Blue Shark is slim
and streamlined, has a very long snout, very big eyes and large pectoral fins.
The Blue Shark is a very beautiful shark (in my opinion), it moves like a gilder through
the water (it glides downwards to the ocean bed and then swims towards the surface
again). Once Blue Sharks were very common but overfishing many places have
threatened the population of Blue Sharks. Today the Blue Sharks are not found
It is said that Blue Sharks can live up to 20 years and the Blue Sharks are
sexually mature at the age of 3. Blue Sharks give birth to live young,
up to 100 per litter, the young ones can be more than 20 in. long. The young
ones of the Blue Shark can take care of themselves when they are born.
Female Blue Sharks have swum from North America to Europe to give birth
and after that return across the Atlantic Ocean.
Blue Sharks lives from 70 degrees north to 50 degrees south (The tip of South America).
If you take a look at a Blue Shark, you can see a similarity with an airplane and
actually their is a good reason for that. Many airplanes are build after the
streamlined body of the Blue Shark.
Blue Sharks are often seen swimming in the surface with its back and dorsal fin
above water. The Blue Shark is very fast, and the shark has a good balance in the water
because of the two large pectoral fins. The Shark is fast and that makes it
able to feed on some of the fastest species of fish in the ocean
e.g. Mackerel, Marlin and Tuna, but the Blue Shark also eat other fish and squids.
Blue Sharks can be dangerous to humans. Usually it is only if a diver wants to feet
them that the sharks have made a mistake and bitten the diver. It can also be dangerous
when they have been captured and they do everything they can to defend themselves.
If you take a look at the unprovoked attacks on humans, then I have only heard
about attacks on children.
