The goblin shark,
is a deep-sea shark, the sole
living species in the family
is
found in the deep ocean, far below
where the sun's light can reach at
depths greater than 200 m. They
can be found throughout the world,
from Australia in the Pacific Ocean
to the Gulf of Mexico in the Atlantic
Ocean. They are best known from
the waters around Japan, where the
species was first discovered. Goblin
sharks feed on a variety of organisms
that live in deep waters.
Among some of their known prey
are deep-sea squid, crabs, and deep
-sea fish. Very little is known about
the species' life history and reproductive
habits, as encounters with
them have been relatively rare. As
seemingly rare as they are however,
there seems to be no real
threat to their populations and so
they are not classified as endangered
species by the IUCN. wo

Male Goblin sharks commonly grow between
2.4 and 3.1 m (7.9 and 10 ft) long and
females between 3.1 3.5 m (10 11 ft). The
largest verified specimen was 3.9 m (13 ft)
and weighed 210 kg (460 lb), although one
unusual specimen was estimated to measure
an enormous 6.2m (20ft). The pink
coloration, unique among sharks, is due to
blood vessels underneath a semitransparent skin (which bruises easily),
thereby causing the colouring. The fins
have a bluish appearance. Goblin sharks
lack a nictitating membrane. They have no
precaudal pit and no keels. The front teeth
are long and smooth-edged, while the rear
teeth are adapted for crushing. Up to 25%
of the goblin shark's body weight
can be its liver. The goblin shark
