Stingray
First of all, we need to understand the stingray. Stingrays are a common species of sharks. The pectoral fins of stingrays are like feathers, swimming in a wave-like motion, as if they are flying in the water. They are very beautiful, so they are loved by many fish lovers. Stingrays are generally gentle and non-aggressive in nature, but they also have self-defense methods: there are often 1 to 3 poisonous stingers on their tail stalks. Therefore, for domestic stingrays, never deliberately tease or excite them. Angry at it.
The main body of the stingray's venomous stinger is produced by a bone-like structure of dentin. There are small serrated overhangs on both sides of the venomous spines. The outer layer of the spines is a sheath, which contains glandular epithelial cells to produce venom glands. The penetration of stingray venom is a total penetration type, which is different from the tubular penetration system of venomous snakes. , that is to say, when the poisonous spines penetrate into the human body, the outer sheath will be damaged and the venom will be released into the body. The toxin of sting rays is probably a neutral unstable protein (Protein Venom) with a molecular weight of more than 100,000. The toxicity will almost disappear after being left at room temperature for 4 to 18 hours or frozen. The toxin composition may contain 30% protein. , 3% nitrogen, 3% sugar, and the rest are mostly unknown factors.
