Hello, I'm Bobby. Today I will talk about the starfish. Many animals live in the sea. One animal that people are familiar with is the fish. There is no end to people's interest and curiosity about it. About 1,500 species of starfish live in seas and oceans, the largest being the sun star.
The length of each arm of the animal is about 2 metres. This fish is found in the North East Pacific Ocean. There are also starfish in Alaska and southern California. For example, coral and tuna are seafish. Because they have a backbone. Again, despite having the same backbone, he is not a fish. She does not lay eggs like other fish; they give birth directly.
Starfish are different. Starfish do not have backbones. Starfish have very different characteristics from vertebrates. Starfish are mainly animals of the Acaena and Dermato groups. There are many types of starfish in the ocean; their common characteristics are a scaly body and five arms. They are commonly called starfish because of these five alarms.
Some starfish have more than 50 organs. The body of a starfish has cerci-like organs. The animal uses them to help it move very slowly towards the sea floor. Starfish have no eyes. On the top of their arms are spots containing a type of pigment that emits light. They search for food through these sensory statutes, no matter how hard and rough starfish are, they prefer hard animals for food.
So molluscs like snails and oysters are their favourite food. Starfish have enzymes in their stomachs that help digest food. Starfish can survive anywhere, be it the rocky seas of the North Sea or any area of aquatic vegetation.
They are ubiquitous. Some starfish can easily live 20,000 feet deep in sand. Marine animals are not exactly social creatures. However, these starfish gather together in quest of nourishment during a specific period of the year.
The eating process of this month is also one of the strangest eating processes in the world. To take any food into his mouth, he has to raise the mouth opening by leaning on five or as many arms as there are. As mentioned earlier, the starfish's favourite food is the soft meat inside the oyster.
