The treasures in the town hall of China Fish Culture Museum seem to be a bit overwhelming, eclipsing all the fish in the collection. On entering the door, a huge sperm whale specimen stood in the center of the museum, next to a white skeleton. It is said that this exhibition hall is specially designed for this sperm whale specimen, and the "treatment" is not high.

This sperm whale specimen and its skeleton are18.4m long, which is the largest sperm whale specimen in China. This whale is named "Sperm Whale" because it can produce a gray or black secretion-Long Xianxiang. It is the most famous of all large toothed whales. It is classified as a family-physeteridae, and has two small close relatives, namely the small sperm whale and the dwarf sperm whale. Therefore, strictly speaking, they are not fish, but mammals.

Sperm whale's head accounts for about 1/3 of its body length, and its nostril position is asymmetrical with the central axis of its body, far to the left, which is a very unique and interesting example of mammalian body asymmetry. Adult sperm whales are generally 15-20 meters long, so this pair of sperm whale specimens in the collection can be described as "tall" of its kind.

Sperm whales eat squid and all kinds of small sharks, so there are stories of sperm whales fighting giant squid all over the world. The king squid looks fierce, but it is actually very fragile, and its blood has poor oxygen carrying capacity. It is a natural "anemia patient". Therefore, sperm whales always win more than lose in the struggle with the king squid. Occasionally, some unfortunate sperm whales are choked to death in the entanglement with the "King Squid". As for why the sperm whale in the collection died, it has become a permanent mystery.
