**Order** is a collection of animals of the same class, taxonomically higher than the phylum. The fossil record of the order Zoophorozoa ends around 541 million years ago. Currently, over **30 orders of planktonic crustaceans are known.** In some orders there are up to 10 or even more thousand species. For higher taxa, superclasses, kingdoms and phyla are usually distinguished instead of orders.

From the middle of the 20th century. There was a significant change in the species composition of the order of bony fish: all freshwater fish became predatory, and by the beginning of the 21st century, the benthic order almost all died out, and the lungfish completely died out from the order, only occasionally the sawnose shark and rays of cartilaginous fish are found. The order of primates is still the most numerous terrestrial vertebrate viviparous. Many species of this order disappeared in ancient times, but insectivores and pinnipeds have existed since the end of the Carboniferous period of the Paleozoic era; extinct animals from the Pleistocene survived
