Here are some examples of archaea, Thermoproteobacteria, Thermococcus, Thermococcus, Thermococcus, Thermococcus, Desulfococcus, Acidophilus, Flammulina, Desulfococcus, Flammulina, Thermococcus and Thiobacillus. Thermococcus belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus, belongs to Thermococcus.

Clawed animals, armored animals, chordates, chordates, subphylum, sea squirts, cephalochordates, subphylum, vertebrates, subphylum, epiphyllum, amphibians, reptiles, birds and mammals. The existing reptiles include four orders: crocodiles, including crocodiles, alligators and caimans. Sphenodontia: It includes two species, * * *, which live in New Zealand. Scale orders: including lizards, snakes and earthworm lizards, with nearly 7,900 species. Turtles: There are nearly 300 species, including turtles and tortoises. Amphibians are divided into three categories, two of which are extinct, and the existing ones include three orders. Labyrinthodontia (extinct), Lepopondyli (extinct), Lepopondyli (Lissamphibia), Apoda (or gymnophonia): 170 species of Anura: 350 species, such as Anura: 3700 species, such as frogs and toads. The progress of rhinoceros suborder (or anthropoid suborder) of Lemuridae, Lemuridae and Macrolemuridae, monkeys, apes and humans. Glasses monkeys, capuchin monkeys, green monkeys, monk-faced monkeys, spiders, monkeys, gibbons, hominids and hominids all belong to primates. In addition to humans, this family also includes all extinct human close relatives and almost all orangutans. Under the classification of some sects, gibbons are also a member of the primitive family. In the traditional bird classification system, passeriformes are a family of birds. ***23 genera 1 17 species.
