Abalone is an animal in the phylum mollusca, which is often called mollusk. Mollusks belong to invertebrates, and compared with vertebrates, they are not very advanced animals. As a kind of mollusk, abalone is also a kind of relatively low-level animals, but their heads are very developed and have many structures on them. Eyes are one of the structures of abalone. Abalones do have eyes. Some people mistakenly think that they don't have eyes because they are not easy to observe. Specifically, abalone's eyes are on their tentacles. Abalone has two tentacles, which can stretch very long. On the back of the bases of their two antennae, there are protrusions. The ends of these two protrusions are abalone eyes, but they are not easy to observe. Although abalone also has eyes, their eyes are different from those of humans and other advanced animals, except that they have the ability to sense around them simply.

As mentioned above, abalone is a mollusk. In addition, abalone is one of shellfish. Abalone has a shell. Their outer body is a shell, and their inner body is soft. This shell belongs to calcareous shell, which feels very hard. The abalone we usually see as an ingredient is only a part of the abalone body and has no shell, so some people think that abalone has no shell. If we can see the whole abalone, we can observe their shells. The color of their shells is green-brown, and the color is very dark; There are many colors inside the shell, such as purple, white and green.
