The fossil family of paleontology belongs to the whole fossil family, in addition, there are 7 superfamilies: Deep-headed, Finger-headed, Diptera, Bermudagrass, Red-headed, Broad-headed and Imitation.
People in different parts of China have different names for prawns, such as "Lai Urine Shrimp", "mantis shrimp", "Mountain Climbing Shrimp", "Mouth Shrimp Squid", "Flower Comes Insect", "Shrimp Bucai", "Rich Shrimp" and "Pipa Shrimp", and so on, and so do Penglai Dajijia and other places.
Extended data:
Squid is a kind of marine crustacean, which has extraordinary vision and is the most complex visual system among the known animals. It can distinguish 12 colors and various forms of polarized light. In contrast, humans can only distinguish three of them.
This is because mantis shrimp's eyes have special photosensitive cells, similar to the 1/4 wave plate in optical experiments (wave plate: an optical device that can generate additional optical path difference between two vertical optical vibrations, usually made of chronometer, calcite or mica with accurate thickness). When light waves pass through this unit, polarization occurs.
This function enables mantis shrimp's eyes to convert linearly polarized light and circularly polarized light to each other. Man-made 1/4 wave plate plays the same role in DVD, CD and other players, as well as digital cameras and video cameras. The difference between them is that these artificial devices are only sensitive to one wavelength of light, while mantis shrimp's eyes almost perfectly support the entire visible spectrum from near ultraviolet to infrared.
