Where is the cuttlefish found
Cuttlefish are cephalopods that are found in shallow temperate and tropical waters. While they may be seen in aquariums and at research institutions in the U.
Cuttlefish are cephalopods , which means they are in the same class as octopus, squid, and nautilus. These intelligent animals have a ring of arms surrounding their head, a beak made of chitin, a shell although only the nautilus has an exterior shell , a head and foot that are merged, and eyes that can form images.
The cuttlefish has two long tentacles that are used to quickly grasp its prey, which it then manipulates using its arms. Both the tentacles and arms have suckers. There are over species of cuttlefish. These animals vary in size from a few inches to several feet in length. The giant cuttlefish is the largest cuttlefish species and can grow to over 3 feet in length and more than 20 pounds in weight. Cuttlefish have a fin that goes around their body, which looks like a skirt.
They use this fin for swimming. When quick movement is needed, they can expel water and move by jet-propulsion. Cuttlefish can change their color according to their surroundings , just like the octopus. This happens thanks to the millions of pigment cells, called chromatophores, that attach to muscles in their skin.
When these muscles are flexed, the pigment released into the cuttlefish's outer skin layer and can control the cuttlefish's color and even the pattern on its skin. This coloration is also used by males for mating displays and to compete with other males. Most species of cuttlefish are not endangered. However, the International Union for the Conservation of Nature lists the giant Australian cuttlefish Sepia apama as near threatened and notes that the ocean acidification caused by increased carbon dioxide in the atmosphere is potentially a threat to all cuttlefish.
Researchers studying cuttlefish vision persuaded these animals to wear 3D glasses—using live shrimp as incentive. Cuttlefish larvae must learn to see and find food while still in their egg casing because their parents leave them to fend for themselves as soon as they are born. All rights reserved.

You may have seen the chalky internal shell, called a cuttlebone washed up on beaches around the UK. These are often used in budgie cages, as a calcium-rich dietary supplement for the bird. Species information Category Squids, octopuses and cuttlefish. Statistics Length: up to 45cm Average Lifespan: 2 years. By undulating these fins cuttlefish are able to hover, crawl and swim. This is achieved by assuming a streamline body shape and quickly squeezing water from a cavity in their body, through a funnel-like siphon which thrusts them backwards.
Cuttlefish are impressive predators. They are able to catch large, fast moving prey such as fish and crustaceans like crabs, shrimps and prawns.
Cuttlefish feed by using their extendable tentacles to catch prey as it moves past. The bite introduces a toxin, to quickly immobilise any troublesome prey. The largest species of cuttlefish in the world is the Australian giant cuttlefish Sepia apama which can grow up to one metre in length and weigh over 10kg.
The smallest is Spirula spirula which rarely exceeds 45 mm in length.
