Toad, also known as Toad Hama (Toad pronounced má alone). Amphibians, with many papules on the body surface and poisonous glands inside, are commonly known as toads, monkeys, thorns and treasures. In China, there are two kinds of toads: Chinese toad and black toad. Venenum Bufonis and Venenum Bufonis extracted from it are in short supply in China.
Toads are amphibians, their skin is covered with pores, and they are not protected by amniotic membrane and shell from birth, which makes them more sensitive to the environment than other groups. Amphibians are considered as weather vanes to detect environmental changes.
Physical characteristics of centipede
Scolopendra's feet are hooked and sharp, and there are poisonous glands at the hook end, which are generally called palatal teeth, claws or poisonous limbs, and can discharge poisonous juice. After being bitten by centipede, its venom gland secretes a large amount of venom, which is injected into the skin of the bitten person along the mouth of the venom gland of palatine teeth to cause poisoning. The toxin is not strong, and it will be painful but not fatal after being stung.
Medicinal centipede is a large lipped polypod with only 2/kloc-0 pairs of walking feet and/kloc-0 pairs of jaw feet. Chikawa, a close relative of centipede, has only 15 pairs of walking feet and 1 pairs of jaw feet. "Stone centipede" has only 15 feet. There are also some centipedes with much shorter feet, including 35 pairs, 45 pairs and as many as 750 pairs.
