The giant octopus
is a silent, intriguing creature of the deep
seas. This marine creature is rather big in
size and some of the giant Pacific octopus can
weigh 270 kgs, the length being 23 ft across
the arm tips.
An octopus has
eight arms and a soft body. Each arm has two
rows of suction cups. If one arm is lost an
octopus can regrow another arm. It has an eye
on each side of its head and cannot hear. This
marine animal has blue blood.
The giant octopus
is a carnivorous, nocturnal hunter. It feeds
on crabs, scallops, snails, fish, turtles, crustaceans
and other octopuses. This animal has a hard
beak and a ribbon of teeth. It injects digestive
juices into the prey to soften it and then the
prey is killed with a bite of its sharp beak.
The octopus takes the prey back to its den for
a leisurely meal.
When it senses
danger this animal is extremely stealthy and
speedy. A giant octopus can quickly change color
and mingle with its surroundings to camouflage
itself. Sometimes they release a cloud of blue
ink to confuse its prey. Then the octopus makes
a speedy getaway by using jet propulsion.
Among all invertebrates,
octopuses have the most complex brain. They
have short term and long term memories. They
can learn to solve problems by trial and error.
Once they learn to solve a problem, they can
solve similar problems in the future.
The giant octopus
has an acute sense of touch in its suckers.
This enables them to differentiate between objects
of various shapes and sizes. The eyes of an
octopus performs the same visual activity as
that of humans. It focuses by moving the lens
in and out.
There are male
and female octopuses. The male has a modified
sucker disc at the tip of one of its arms. During
mating, the male uses the modified arm to remove
a packet of sperms from within his mantle cavity
and inserts it into the mantle cavity of the
female. Two months after mating, the female
attaches strands of eggs to the ceiling of her
den.
The female gently
caresses the eggs to prevent algae and bacteria
from growing on them. She gently squirts the
eggs with water from her siphon to keep them
oxygenated. Most females stay in the den and
starve, in order to take care of the eggs. They
die soon after the eggs are hatched. The male
giant octopus after mating goes away into deeper
waters and dies a couple of months later.
Hence, on studying
the behavior and life cycle of a giant octopus
we find that they are very intriguing deep sea
creatures and a fascinating example of marine
life.
