Arnidovirineae is a suborder of viruses in the order Nidovirales. There are 4 families and 16 genera in the Arnidovirineae suborder.
Hosts
For species that fall under the Arnidovirineae suborder, large mammals serve as natural hosts, with sizes varying from mice to boars and horses. However, for 3 genera snakes and turtles serve as natural hosts.
Genome
Viruses in this suborder have relatively small genomes compared to other suborders in the Nidovirales order, ranging from 12-16kb. These genome differences are the primary identifying factor of the suborder. Species of Arnidovirneae have been found all around the world.
