In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species.

Arianism is a nontrinitarian Christological doctrine which asserts the belief that Jesus Christ is the Son of God who was begotten by God the Father at a point in time, a creature distinct from the Father and is therefore subordinate to him, but the Son is also God. Arian teachings were first attributed to Arius, a Christian presbyter in Alexandria of Egypt. The teachings of Arius and his supporters were opposed to the theological views held by Homoousian Christians, regarding the nature of the Trinity and the nature of Christ. The Arian concept of Christ is based on the belief that the Son of God did not always exist but was begotten within time by God the Father.

Arius was a Libyan presbyter and ascetic, and priest in Baucalis in Alexandria, Egypt. His teachings about the nature of the Godhead in Christianity, which emphasized God's uniqueness and the Christ's subordination under the Father, and his opposition to what would become the dominant Christology, Homoousian Christology, made him a primary topic of the First Council of Nicaea, which was convened by Emperor Constantine the Great in 325.

Friedrich Wilhelm Schulz was a German officer, radical, and social democratic publisher in Hesse. His most famous works are Der Tod des Pfarrers Friedrich Ludwig Weidig as well as Die Bewegung der Produktion, which Karl Marx quoted extensively in his 1844 Manuscripts.
