2. Stingray
Stingrays will also have white stripes or white dots on the body, stingrays are not strong in activity, easy to catch, the edible value is not very high, but stingray meat is more.
Stingers have barbs at the front end, which is difficult to remove, so fishermen cut off the part of the fish tail stinger after catching, and the stingray spines are mainly composed of ivory cartilage tissue, and the spines of adult fish are generally about ten centimeters long.
The outer layer of the spine is the outer sheath, which contains glandular epithelial cells, which form poisonous glands. The secretion of stingray toxin is mainly a total secretion type, that is to say, when the poisonous spines penetrate deep into the body, the outer sheath will be destroyed and the venom will be released into the body, but after the stingray is freeze-dried, this toxicity will slowly disappear.
