The meerkat is a small animal that can stand and move its head flexibly. The meerkat is a small mammal that typically lives in areas such as deserts, wilderness areas and grasslands. They generally feed on insects, small mammals, birds and reptiles. Meerkats can move their heads flexibly, making it easier for them to find prey and avoid predators. At the same time, meerkats can also stand upright to better observe their surroundings.
Mantis shrimp. Marine crustaceans of the order Stomatopoda, particularly species of the genus Squilla. The second pair of appendages is very large and resembles the front legs of a praying mantis, hence its English name meaning mantis shrimp. There are more than 250 species, widely distributed, ranging from 1 to 30 centimeters (0.4 to 12 inches) in length. Lives in coastal waters but can also be foundat depths of 1,300 meters (about 4,300 feet). Most live in caves. Larvae and adults are good swimmers. The mantis shrimp (S. mantis) is commonly found in Mediterranean and adjacent Atlantic waters. It is 20 centimeters (about 8 inches) long and lives in sediment and organic debris. The ghost shrimp (S. empusa) is the most common species along the Atlantic coast of North America. Oratosquilla oratoria, which grows along the coast of Japan, is edible and can reach up to 20 centimeters in length. There is only the order Stomatopoda in the subclass Pleurozoa, among which, with the exception of Palaeozoonidae, which are all fossil species, the extant species are divided into 4 superfamilies: Mantiseoidea, Dactyloidea, Mantiseoidea and Superfamily Lymphridae. All are sailors. There are over 300 species of predatory shrimp originating from the Jurassic period ofand the Mesozoic era. Most species live in tropical and subtropical regions, with a few found in temperate zones. They are found all along the coast of China, with the greatest number of species in the South China Sea, with over 80 species discovered.
