Cuttlefish

Cuttlefish are not fish!

Cuttlefish are aquatic animals of the mollusc type, and they are cephalopods that feature a pronounced head and a total of ten tentacles, eight of which are short.
Cuttlefish are typically 15 to 50 centimetres (6 to 20 inches) in length, plus the length of the tentacles, and weigh 3 to 10.5 kilograms (6.6 to 23 pounds).
There are approximately 120 species of cuttlefish, and they are from the order with the scientific name Sepiida, that contains five families, and they are related to octopus and squid.
The diet of cuttlefish consists primarily of fish, crabs, molluscs, shrimp and worms, among others.
Due to their ability to change body colour for camouflage purposes or other reasons, as well as the differences between species, cuttlefish can come in a variety of colours, including red, pink, yellow, green, brown, white and blue.

Inside a cuttlefish there is distinct aragonite porous shell, known as a ‘cuttlebone’ that is often found on the beach and fed to pet birds as a source of calcium, and the blood of the animal is coloured a greenish-blue and pumped around by three hearts.
Poison that can be lethal and is used to paralyse its prey, is produced by a cuttlefish in its mouth, and the animal captures its prey by two long tentacles that propel out from its body and later retract.
To protect itself from predators such as sharks and large fish, cuttlefish may use camouflage or produce ink to obscure the other animal’s vision.
To find a mate, a male cuttlefish will change its skin colour for appeal, while females die after laying approximately 200 eggs; and the animal has an average lifespan of one to three years.
Cuttlefish can be found in most oceans around the world, however they do not live around North or South America; and some cultures enjoy the animal as food, and they are commonly dried and shredded and eaten as a snack.
