Two of the orders are closely-related enough that they are lumped into a classification called "Glires": Rodentia, the rodents, and Lagomorpha, the rabbits and pikas. The other three orders are Dermoptera, the flying lemurs, Scandentia, the tree shrews, and Primates. This page discusses all but the primates, which will be discussed on the following pages.
- Xenarthra [38-V]
- Afrotheria [38-VI]
- Boreoeutheria
- Laurasiatheria
- Perissodactyla - Horses, Tapirs, Rhinoceroses [38-VII]
- Insectivora - Hedgehogs, Shrews, Moles [38-VII]
- Pholidota - Pangolins [38-VII]
- Chiroptera - Bats [38-VII]
- Artiodactyla [38-VIII]
- Carnivora [38-IX]

- Rodentia - Rodents
- Lagomorpha - Rabbits, Pikas
- Dermoptera - Flying Lemurs

Rodentia is, by far, the largest order of mammals with 225 species observed in iNaturalist in the US and 1,233 throughout the world.
