The Duckbill Duckbill is not a native freshwater fish species in China it is a carnivorous fish species with rough flesh and is too large.
Mainly because the duckbill looks too strange, and there is no related popularity in China, so it is not recognized by the public, China is also less farmed, expensive, so the sales of duckbill is generally not very good, the duckbill is less on the market duckbill sold.

The duckbill's head can be relatively long, and the head length can reach more than half of the body length. The eyes of the platypus are also small, oval-shaped, and located in the lateral position.
Platypus habits
The male platypus hind feet have thorns, memory of poisonous juice, spraying can hurt, almost similar to the venom of snakes, if a person is stung by the venomous pitch, that is, causing severe pain, to months to recover. This is its "amulet".
The platypus is an amphibious animal, usually like burrowing in the water, in the water when the eyes, ears, nose are tightly closed, only by perception with the flat soft "duck's beak" foraging shellfish. It is a big eater and consumes as much food as its own body weight every day.
While the mother also secretes milk to feed her young, she is not a fetus but an egg. That is, the eggs are laid by the mother and incubated by the mother's temperature like birds. The mother does not have breasts and nipples, but produces milk on the sides of the abdomen, and the cubs lick at the mother's abdomen.
Larvae have teeth, but the adult dental bed without teeth, but by the continuous growth of the horny plate instead, the plate in front of the occlusal surface to form a number of elevated transverse ridges, used to crush shellfish, snails and other mollusks, shells, or chopped up other food, the back of the horny plate was flat, and the plate is opposed to the flat tongue has an auxiliary "masticatory" role. The role of the flat uvula opposite the plate has an auxiliary "chewing" function.
The platypus chases the platypus through the water, and its eggs resemble a turtle's egg. After hatching, the baby platypus is breast-fed for four months before it is able to forage for food on its own. The biological clock of the platypus is inverted, they used to sleep during the day, night activities. The platypus can snorkel and often builds dens on the banks of swamps or rivers with openings underwater, including mountain streams, stagnant or polluted rivers, lakes and ponds.
It digs holes in the bank as a hideout, with the burrow connected to the adjoining water. It is an underwater forager, diving for food for about a minute at a time, exploring the mud with its mouth for shellfish, worms and crustacean critters as well as insect larvae and a variety of other animal foods and some plants.
