The largest toad in the world
Bufo marinus, also known as American giant toad, cane toad, cane toad or cane toad, is the largest toad and the third largest frog in the world. In the wild, female toads often weigh more than one kilogram.
Sea toads are hardly afraid of any carnivores, because the liquid glands in their skin can be highly toxic. Sea toads usually eat at dusk, mainly insects, frogs, lizards and small rodents.
Sea toad is a kind of terrestrial toad that originated in Central America and South America, and was later introduced to Australia, which is widely distributed in the east coast and northern part of the Australian mainland. Their reproductive ability is very strong, and they can lay thousands of eggs at a time. Adult body length10-15cm; The largest specimen recorded weighs 2.65 kg and is 38 cm long.
The sea toad was originally used to eliminate pests on sugarcane, so it is also called sugarcane toad, sugarcane toad or sugarcane toad. They are also called American giant toads because of their large size. The sea toad comes from its scientific name.
They were made by Carl? Described by Linnaeus. Linnaeus chose this nickname because Albertus Seba mistakenly described the sea toad as terrestrial and aquatic at that time. In Australia, sea toads are very similar to local Limnodynastes and Mixophyes.
The difference is that the sea toad has a large parotid gland behind its eyes, and there is no ridge between its nostrils and its eyes. They are very similar to the toads produced in Zexue, Australia. Both of them are large in size and uneven in appearance, but the iris of the sea toad is straight and silver-gray. The larval sea toad is also very similar to the genus Bufo, but the color of adult thighs is obviously different.
Among about 500 members of Bufonidae, the sea toad (Rhinella marina) is generally considered as the largest. According to the Guinness Book of World Records, the largest sea toad lives in Sweden as a pet. This one is called? Prinsen? The length of the sea toad is 38 cm, and when it is fully extended, it is 54 cm long and weighs 2.65 kg.
The female frog of sea toad is obviously longer than the male frog, reaching10-15cm. The greater tendency of sea toad is distributed in the sparse community. The life span of wild sea toad is 10- 15 years old, and those raised can live longer, and the oldest can reach 35 years old.
The skin of sea toad is dry and pimples. The eyes are obviously ridged and straight to the snout. They are gray, yellow, auburn or olive brown, and can have different stripes. There are large parotids behind the eyes. The abdomen is milky white with black or brown pimples. The pupil is transverse and the iris is golden. There is a fleshy web at the base between the toes, but no web on the forelimbs.
Young toads are relatively small, only 5- 10 cm long. Their skin is generally smooth and dark, and some are even reddish. Young toads have no parotid gland, so their toxicity is weak. Tadpoles are small and black, and live in groups at the bottom of the water. Tadpole length 1-2.5 cm. The greater tendency of sea toad is distributed in the sparse community.
The Australians made a silly and lovely wrong decision. In order to control the pests in sugarcane fields, they introduced a large number of sea toads, expecting them to eat up the sugarcane pests.
However, contrary to expectations, the worms were lying on the sugarcane stalks, and the sea toad could not eat them at all, so the sea toad found another way to find alternative food. But they have a good appetite and breed wildly. They eat almost anything, from insects to reptiles to small rodents.
This has a serious impact on the local food chain. Secondly, their venom can kill many predators and make them strong without natural enemies in Australia. Many reasons eventually led to the flooding of sea toads. The longest sea toad can be 15 inch (about 38 cm) long.
In addition to biological control of pests, sea toad also has many commercial and non-commercial uses. South American aborigines will paint the secretion of sea toad on hunting arrows, and some Olmecs also use it as an anesthetic. They are even used as food in Peru, but the skin and parotid gland must be removed before eating. Japan uses bufotoxin as an aphrodisiac and hair regeneration medicine; China also uses it to lower the heart rate of patients undergoing heart surgery.
On 20th13 10/5 local time, the tannery of Jean-Charles, a luxury brand in Mi Yue, France, was filled with dried Australian cane toads. Many years ago, France introduced this kind of toads from South America to deal with the local beetle disaster, but now their skins have become expensive luxury materials.
