Rictus is a genus of Bikosea, a small group of unicellular flagellates, included among the heterokonts. The only species in the genus is Rictus lutensis.
Jackals are canids native to Africa and Eurasia. While the word "jackal" has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal and side-striped jackal of sub-Saharan Africa, and the golden jackal of south-central Europe and Asia. The African golden wolf was also formerly considered a jackal.
Acinonyx is a genus within the Felidae family. The only living species of the genus, the cheetah, lives in open grasslands of Africa and Asia.
The Gruiformes are an order containing a considerable number of living and extinct bird families, with a widespread geographical diversity. Gruiform means "crane-like".
Eutheria, also called Pan-Placentalia, is the clade consisting of placental mammals and all therian mammals that are more closely related to placentals than to marsupials.
Requiem sharks are sharks of the family Carcharhinidae in the order Carcharhiniformes. They are migratory, live-bearing sharks of warm seas and include such species as the bull shark, lemon shark, blacktip shark, and whitetip reef shark.
Gavialidae is a family of large semiaquatic crocodilians with elongated, narrow snouts. Gavialidae consists of two living species, the gharial and the false gharial, both occurring in Asia. Many extinct members are known from a broader range, including the recently extinct Hanyusuchus. Gavialids are generally regarded as lacking the jaw strength to capture the large mammalian prey favoured by crocodiles and alligators of similar size so their thin snout is best used to catch fish, however the false gharial has been found to have a generalist diet with mature adults preying upon larger vertebrates, such as ungulates.
Phrynocephalus is a genus which includes 33 species of small and medium-sized agamid lizards, commonly called toadhead agamas or toad-headed agamas, that inhabit open arid and semiarid environments of Asia and Eastern Europe. The systematics of this genus are very complicated with many controversial points of view about the unclear phylogeny of this group. All representatives of this genus have adopted the so-called "sit and wait" hunting strategy and they actively use visual orientation when watching for food. In general, the ecological niche and role of Phrynocephalus species in lizard communities of arid environments of Asia are poorly studied, but seem to be similar to that of Phrynosoma, Cophosaurus, Holbrookia, Uta, and Sceloporus in the New World, as well as Moloch in Australia.
Wanted is a comic book limited series created by writer Mark Millar and artist J. G. Jones. It was published by Top Cow in 2003 and 2004 as part of Millarworld. It features an amoral protagonist who discovers he is the heir to a career as a supervillain assassin in a world where such villains have secretly taken control of the planet. The Sunday Times dubbed the title "the Watchmen for super-villains."
Jehan Rictus was a French poet. He was born Gabriel Randon in Boulogne-sur-Mer. In the 1900s, he legally changed his name to his mother's name Randon de Saint-Amand.
Risus sardonicus or rictus grin is a highly characteristic, abnormal, sustained spasm of the facial muscles that appears to produce grinning. It may be caused by tetanus, strychnine poisoning, or Wilson's disease, and has been reported after execution by hanging.
The genus Cathartes includes medium-sized to large carrion-feeding birds in the New World vulture (Cathartidae) family. The three extant species currently classified in this genus occur widely in the Americas. There is one extinct species known from the Quaternary of Cuba.
Surdisorex is a genus of mammals in the family Soricidae. Surdisorex is one of three genera of African shrews, which, in turn, are one of three living subfamilies of shrews. Species in the genus Surdisorex are called African mole shrews because of their similarity to moles, to which they are not closely related.
Barbastella is a genus of vespertilionid bats. There are seven extant species in this genus and one only known from fossil remains.
Thalassemys is a genus of extinct thalassochelydian turtle from the Late Jurassic of western and central Europe. While the genus was originally named by Rütimeyer in 1859 for a large carapace and other associated fragments from the late Kimmeridgian of the Reuchenette Formation of Switzerland, although the taxon was not validly named until 1873 when Rütimeyer designated the type species T. hugii. Rütimeyer also named T. gresslyi from the Reunchenette Formation in the same paper as T. hugii, but it cannot be differentiated from the type material of T. hugii and is therefore a junior synonym. A large assemblage of shell and postcranial material from the Reunchenette was named as a species of Eurysternum, E. ignoratum, by Bräm in 1965. While originally distinguished based on the presence of fontanelles on the plastron, the feature was later identified on T. hugii and E. ignoratum was designated a junior synonym. Additional material from the Kimmeridge Clay of the United Kingdom has also been referred to T. hugii.

Saurorictus is an extinct genus of Late Permian captorhinid known from Western Cape Province of South Africa.
Soriculus is a genus of shrew native to Asia. Along with several fossil species, the only extant member of the genus is the Himalayan shrew, as other extant species have now been transferred to other genera.
Iranotricha is a genus of ground spiders containing the single species, Iranotricha lutensis. It was first described by Alireza Zamani & Yuri M. Marusik in 2018, and is only found in the Lut Desert, Iran.
Phrynocephalus lutensis, the Lut Desert toad-headed agama, is a species of agamid lizard found in Iran.
Ferula assa-foetida is a species of Ferula endemic to Southern Iran. It is a source of asafoetida, but not the main source, although many sources claim so. The production of asafoetida from this species is confined to Southern Iran, especially the area near Lar.
