Oestrus is a genus of bot flies, from the family Oestridae
The genus includes the sheep bot fly (O. ovis Linnaeus, 1758) that is a major pest in the Australian sheep industry.
About 34 species are in the genus.
Conidae, with the current common name of "cone snails", is a taxonomic family of predatory sea snails, marine gastropod molluscs in the superfamily Conoidea.
The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family Bovidae, and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine.
The mouflon is a wild sheep native to Cyprus, the Caspian region from eastern Turkey, Armenia, Azerbaijan, and Iran. It is thought to be the ancestor of all modern domestic sheep breeds.
The urial, also known as arkars, shapo, or shapu, is a wild sheep native to Central and South Asia. It is listed as Vulnerable on the IUCN Red List.
Strombus is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives. The genus Strombus was named by Swedish Naturalist Carl Linnaeus in 1758. Around 50 living species were recognized, which vary in size from fairly small to very large. Six species live in the greater Caribbean region, including the queen conch, Strombus gigas, and the West Indian fighting conch, Strombus pugilis. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides.
Ovis is a genus of mammals, part of the Caprinae subfamily of the ruminant family Bovidae. Its seven highly sociable species are known as sheep or ovines. Domestic sheep are members of the genus, and are thought to be descended from the wild mouflon of central and southwest Asia.
The snow sheep, or Siberian bighorn sheep, is a species of sheep from the mountainous areas in the northeast of Siberia. One subspecies, the Putorana snow sheep (Ovis nivicola borealis), lives isolated from the other forms in the Putoran Mountains.
The Marco Polo sheep is a subspecies of argali sheep, named after Marco Polo. Their habitat are the mountainous regions of Central Asia. Marco Polo sheep are distinguishable mostly by their large size and spiraling horns. Their conservation status is "near threatened" and efforts have been made to protect their numbers and keep them from being hunted. It has also been suggested that crossing them with domestic sheep could have agricultural benefits.
Ostrea is a genus of edible oysters, marine bivalve mollusks in the family Ostreidae, the oysters.
Ixodes ricinus, the castor bean tick, is a chiefly European species of hard-bodied tick. It may reach a length of 11 mm (0.43 in) when engorged with a blood meal, and can transmit both bacterial and viral pathogens such as the causative agents of Lyme disease and tick-borne encephalitis.
Mormyrus is a genus of ray-finned fish in the family Mormyridae. They are weakly electric, enabling them to navigate, to find their prey, and to communicate with other electric fish.
Melophagus is a genus of biting flies in the family of louse flies, Hippoboscidae. There are three known species and one subspecies. All are parasites of bovids. All are wingless.
The 10th edition of Systema Naturae is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of Species Plantarum.
The Mammalia in the 10th edition of Systema Naturae forms one of six classes of animals in Carl Linnaeus's tenth reformed edition written in Latin. The following explanations are based on William Turton's translations who rearranged and corrected earlier editions published by Johann Friedrich Gmelin, Johan Christian Fabricius and Carl Ludwig Willdenow:
Animals that suckle their young by means of lactiferous teats. In external and internal structure they resemble man: most of them are quadrupeds; and with man, their natural enemy, inhabit the surface of the Earth. The largest, though fewest in number, inhabit the ocean.
In the 10th edition of Systema Naturae of 1758–1759, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". He described the Insecta as:
A very numerous and various class consisting of small animals, breathing through lateral spiracles, armed on all sides with a bony skin, or covered with hair; furnished with many feet, and moveable antennae, which project from the head, and are the probable instruments of sensation.
In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Insects with simply two wings were brought together under the name Diptera.
Oestrus ovis, the sheep bot fly, is a widespread species of fly of the genus Oestrus. It is known for its parasitic predation and damage to sheep, deer, goats and sometimes cattle. There have also been many records of horse, dog and human infestation. In some areas of the world it is a significant pest which affects the agricultural economy.
Bovicola is a genus of lice belonging to the family Trichodectidae.
