The Common Cuttlefish (scientific name Sepia officinalis) is also known by the name European Common Cuttlefish. They are the largest Cuttlefish species that are known and identified. They are migratory mollusks and tend to live in specific temperate and tropical environments. They are mostly found in southern and eastern parts of Asia, coastal regions of Australia and Africa, and in Europe. They can survive on sandy and muddy lands and have a high tolerance for brackish water. They also inhabit the Mediterranean seas. They have a big size and are bigger as compared to Channel Catfish and Rainbow trout. Cuttlefish are large animals and contain a mantle that stores the internal shell named cuttlebone. The internal shell provides buoyancy to the animal. Cuttlebone has a high market value in the bird industry since it can be used to shape the beak of a bird and are a high source of calcium. These cephalopods can change the texture of their skin and can disguise themselves to camouflage. They can change color due to the presence of light scattering leucophores on their skin. They have highly developed eyes which help them to see light around their surroundings inside water. They are predators and capture animals with the aid of their eight arms and two tentacles. They then immobilize the animals completely with the help of the ink secreted by their body. They breed in the summer and spring seasons and use their camouflage abilities to search and attract partners. Read on to discover more about these exciting cephalopods!
