The one above, don't teach me. The tortoise is a reptile!
There are phylum, class, order, family, genus and species
In general, there are invertebrates and vertebrates
The former includes many, many: annelids (earthworms, leeches, etc.), flatworms (pork tapeworms), molluscs (snails, mussels), arthropods. Arthropods are a large group, divided into spiders (spiders), crustaceans (shrimp, crab), insects (ants, butterflies, grasshoppers, dragonflies, longicorn)
Vertebrates: fish, amphibians (frogs, salamanders, etc.), reptiles (turtles, lizards, and extinct dinosaurs), birds, mammals
In fact, the above statement is not accurate to a certain extent, and can only be used as popular science knowledge. Each group can be further divided many times!
