The difference between puffer fish and puffer fish

Puffer fish is a general term for mammals of the freshwater dolphin family of cetaceans. It is the most affectionate mammal among mammals. The general name of the puffer fish of the family Tetranychidae, named the river "dolphin" because of the pig-like chirp when catching out of the water, also known as bubble fish, belly fish, puffer fish, street fish, wax head, boat fish, and so on. Let's take a look at the difference between puffer fish and puffer fish.

The difference of families and genera between puffer fish and puffer fish

1. Puffer fish: puffer fish is the general name of mammals of the family Freshwater dolphins of the suborder Cetacea, suborder Cetacea, subphylum Vertebrata, subphylum Chordata, subphylum Vertebrata.

2. Fugu: Fugu belongs to the phylum Chordata, subphylum vertebrate, Radioptera, Coleoptera, Coleoptera and Oriental Fishes in the animal kingdom.

Morphological differences between puffer fish and puffer fish

1. Puffer fish: the puffer fish is larger than the dolphin and can grow up to 3 meters long. unlike the dolphin, the head can rotate 90 degrees, which gives it an advantage in complex rivers. Sometimes, like dolphins, they chase schools of fish together to improve predation efficiency. There is sensitive hair on the jaws, which is said to be the tactile organ that preys on crustaceans in the mud. They have wide pectoral fins, which increases their flexibility in narrow rivers, and the speed of their caudal fins can reach 23 km / h in a short time.

2. Puffer fish: the river puffer is cylindrical in shape and has a well-known round body, with a body length of about 100mm to 300mm, and a large one to more than 630mm. The upper and lower jaw and the tooth healing form four large dental plates with a body length of 1.1 meters. 1 dorsal fin, no ventral fin. Without scales or with small spines. There are airbags that can inhale and expand.

The difference of producing area between puffer fish and puffer fish

1. Puffer fish: the freshwater fish family has four existing species that inhabit freshwater rivers and estuaries, of which three live in the Tanshui River, while the other species Plata puffer fish (La puffer fish) lives in the saltwater estuary and inshore oceans. However, in the scientific classification, it is still included in the freshwater fish family rather than the dolphin family.

2. Fugu: Fugu is rich in resources in China. 54 species are produced along the coast of China, with an annual output of about 300 ~ 4 million tons, which can be caught almost all the year round. In the Yangtze River and Pearl River, the flood season occurs between spring and summer, which is one of the main fishery objects in the coastal areas and the middle and lower reaches of the rivers.

The difference of toxicity between puffer fish and puffer fish

1. Puffer fish: puffer fish is a general term for fishes of the family Coleoptera, which is distributed in coastal areas and rivers entering the sea. some species of organs and blood are highly toxic (called tetrodotoxin).

2. Puffer fish: puffer fish is a general term for mammals of the freshwater dolphin family, such as Baiji dolphin, which mainly lives in rivers and has non-toxic abdominal organs. Note that the term "puffer fish" here does not refer to poisonous puffer fish (puffer fish), but a general term for freshwater dolphins (aquatic animals). The well-known dolphins correspond to them.
