I have recently been studying one of the most fascinating
and unheard of creatures. It is one of the largest fish on the planet, yet most
will never have heard its name.
The Greenland shark, as its name suggests, lives in the
arctic region. It can grow to around 7 meters long, making it larger than many
Great White sharks. It is however not quite as scary. It has a cruising speed
of 0.5 mph and when it's really excited it can reach around 1.5mph.
It is thought to feed mainly on scavenged meat such as polar
bears and reindeer, but does also eat seal and fish when it can get it. Due to
the sharks slow speed it is thought that it can only catch seals which are
asleep.
Another bizarre fact about the Greenland shark is that they
are nearly all blind. This is due to a parasite called a Copepod. This lives
exclusively in the eye of the Greenland shark and is thought to give the sharks
eye a green luminescence. There is even a theory that the light attracts fish
to the shark enabling it to suck the food in to its mouth.
It is the only shark that lives in the waters of the Arctic,
enjoying temperatures of up to -2dgs. The extreme temperature they live in is
in someway responsible for the most amazing fact about this shark. To survive
in such conditions, the Greenland shark has had to lower its metabolism. The
upshot of this is that they can live for 200 years, making them one of the
longest living creatures on Earth.
Fascinating dear Brother Driblystick!
