It doesn't matter, as long as it's not alive, its toxicity will be very low. When eating, just pull out the thorns on its tail with pliers, or simply hide the tip of its tail.

Under normal circumstances, fishermen have removed the stinger 2 inches from the tail when fishing for rays, so it is difficult to see the stinger when eating.

Because there is no hard gill cover protection like bony fish, it is necessary to avoid touching its gills when fishing to prevent the fragile gills from being damaged. No swim bladder. They will sink to the bottom when they are not swimming.

Introduction to ray:

1, Leigh's endoskeleton is completely composed of cartilage, and the whole skeleton is similar to the brittle bones in our ears. Some parts also have a certain hardness after calcification, but it is different from the hard bone tissue formed by ossification. The body surface is covered with tarsal scales and is formed by ectoderm and mesoderm. The scales and teeth of ferns are homologous structures. The position of the mouth is not in the snout, but on the ventral surface, which is transverse (so it is called transverse mouth); The lateral fin is in a horizontal position; The tail fin is crooked.

2. The differentiation of the stomach is obvious, with an independent pancreas and a developed liver. There is a spiral valve in the intestine. No swimming. The branchial septum is very long, extending to the body surface and connected with the skin, so the branchial fissure opens directly to the body surface. The heart has an arterial cone. The male reproductive tube is borrowed from the middle renal tube. A single cloaca opens outward. Males have mating organs called flippers.

3. Oviposition, viviparous or pseudoviviparous, in vivo fertilization, in vitro development or in vivo development. Fewer eggs are laid, but the survival rate is high. The brain is developed and more advanced than bony fish. The brain is very big, and there are nerve substances at the top of the brain.

It should be pointed out that:

Rays (yáo) are non-toxic and are a general term for many kinds of flat cartilaginous fishes. There are more than 100 species of rays found all over the world, which are distributed in all temperate and tropical shallow waters except the South Pacific and the northeast coast of South America.

The body is monochromatic or patterned, most kinds of ridges have spines or thorns, and some tail parts have power generation organs, so the power generation ability is weak. Rays vary in size: adult fish are only 50 cm; Giant rays can be as long as 2.5 meters. Rays feed on mollusks, crustaceans and fish, and suddenly rush down from above and pounce on their prey.
