First, the giant salamander
Chinese giant salamander is an amphibian of Amphibia and Cryptbranchiaceae, which lives in fresh water. It is a precious wild animal that is a specialty of China, commonly known as "giant salamander". However, it is not a fish, but the largest amphibian, with a body length of about 1 m, the longest reaching 2 meters, weighing 20-25 kg and the largest reaching 50 kg.
Second, squid
Squid, also known as soft fish and squid, is an eye-opening suborder of Cephalopoda Sheath, a suborder of mollusca. The body is cone-shaped, pale with light brown spots, with a big head, touching feet 10 in front, and the fleshy fins at the tail end are triangular, often swimming in groups in the ocean about 20 meters deep.
Third, crocodiles
Crocodiles are carnivorous and oviparous vertebrate reptiles. They are the oldest reptiles contemporary with dinosaurs more than 200 million years ago and one of the most primitive animals that have survived so far. Crocodile's eyes grow on the upper end of its head. Besides its eyelids, it also has a transparent instantaneous membrane, which makes it adapt to the underwater environment.
Fourth, abalone
Abalone, which is called fish, is actually not a fish. It is a primitive marine shellfish and a single-shell mollusk. Because its shape is just like a human ear, it is also called "sea ear". Abalone usually grows on the seabed with low water temperature, covering the Pacific Ocean, Atlantic Ocean and Indian Ocean. It is recognized that the best producing areas are northern Japan and Mexico, and northeast China is also a traditional producing area.
V. Whales
Cetacea is a traditional taxon under Mammalia, which includes about 90 existing fish-like aquatic mammals with bare skin and their extinct early relatives, collectively known as cetaceans or cetaceans. In order to adapt to the underwater environment, the forelimbs of whales evolved into fins and the hind limbs degenerated. Noses are mostly born on the top of the head, which is convenient for breathing out of the water. It has a well-developed hearing and sonar system, and mainly relies on the echolocation function when it is active.
