Horse
The horse adapted to survive in areas of wide-open terrain with sparse vegetation, surviving in an ecosystem where other large grazing animals, especially ruminants, could not. Horses and other equids are odd-toed ungulates of the order Perissodactyla, a group of mammals that was dominant during the Tertiary period. In the past, this order contained 14 families, but only three—Equidae (the horse and related species), Tapiridae (the tapir), and Rhinocerotidae (the rhinoceroses)—have survived to the present day.
Empusidae
Empusidae belong to the superfamily Mantoidea, (“higher” mantises), together with Mantidae and Hymenopodidae [5]. Phylogenetic studies place Empusidae as a sister group to Hymenopodidae. Empusidae and Hymenopodidae are in turn placed as sister groups to all other ambush mantids [3]. There are two subfamilies within Empusidae, Blepharodinae and Empusinae. The Blepharodinae subfamily holds three genera, Blepharodes, Blepharopsis and Idolomantis. The Empusinae subfamily is divided into two tribes, Empusini and Idolomorphini. The Empusini tribe holds five genera, Dilatempusa, Empusa, Gonglyus and Hypsicorypha (see List of mantis genera and species). The Idolomorphini tribe holds the three remaining genera,Hemiempusa, Idolomorpha (see List of mantis genera and species) and Chopardempusa [6]. The latest phylogeny was revised by Svenson et al. 2015 [1].Svenson, Gavin J., et al.
