What are the sepia?

sepia are marine molluscs in the order of sepiis, with approximately 100 species known to exist on Earth. These molluscs are closely related to their colleagues Cefalopods such as Octopus and Octopus, but have several unusual features that postpone them aside from their relatives and other sea animals. People are interested in sepia for many reasons, from the potential source of food to the rich areas of research, although many laymen with these unusual and in fact rather fascinating molluscs.

Although the ordinary name includes the word "fish", they are not at all fish. They resemble their relatives more octopus, with 10 grasped arms and a unique inner shell of a rich calcium known as sepia. The cap can be filled with different gas levels to adjust the buoyancy of the sepia, and these animals move by means of a power drive using their complex fins to control their way with water. Although cuttlefish is not as fast as octopus, they are very fast moving. This stvOut is able to plant ink in self -defense, such as their relatives, and can also change the color and texture of their skin for camouflage. In addition to changing mixing colors, sepia also changes its color to send signals to other sepia, and some species are quite charming and create intense red and orange displays.

sepia have three hearts to draw their blue to green blood rich in copper. Each frog has a dedicated heart, with the third heart manipulation with the general circulation in the body. These animals require three hearts because their blood is not very effective in transporting oxygen, so they have to work harder to get oxygen through their bodies. Eyes of sepia are also unusual, with very distinctive W -shaped pupils, Rather than a classic rounded or vertical pupil, most people would expect.

sister, ink, known as sepia, has been used for centuries for centuries for writing and sepia with pThey use as a source of food in some areas of the world. The shout is also useful as a dietary supplement for birds for pets, many of which need more calcium to prosper. Biologists are very biased because these molluscs are very intelligent and very social. By studying the intelligence and behavior of sepia, scientists hope to learn more about different types of intelligence on Earth and how they interact.
