Cuttlefish or cuttles are marine animals of the order
Sepiida. They belong to the class Cephalopoda, which also includes squid,
octopus, and the nautilus.

Cuttlefish are truly amazing marine creatures. This
alien-like animal has eight sucker covered arms and two tentacles growing out
of its well-developed head, three hearts pumping blue-green blood, and a highly
complex brain.


Their eyes have W-shaped pupils that give them a wide range
of vision, enabling them to almost see behind themselves. Even though they are
colorblind, cuttlefish are able to see polarized light.


Despite their name, cuttlefish are not fish but molluscs. They
have a bone in the middle of the body, known as “cuttlebone” which is filled
with gas, and just like divers, they can control their buoyancy using it.


To avoid predators they can change both the colour and
texture of their skin instantaneously. Using jet propulsion, they can swim at
great speed over short distances, and may release an ink cloud to confuse
predators.


A new study revealed that cuttlefish also respond to
predators by freezing, and dramatically reducing the electrical signals emitted
by them that might give away their presence. These unique abilities place them
amongst the best camouflage experts in the marine world.


Cuttlefish feed on smaller animals such as crabs, shrimp,
fish and small molluscs. It is fascinating how they turn their bodies into
pulsating light and color in an attempt to hypnotize their potential prey.


This intelligent creature lives 1 to 2 years and the females
die shortly after spawning. They are usually 15-25cm long, and 3-10 kg weight.
Generally speaking these molluscs are not high on the list of endangered
species.
