In the 10th edition of Systema Naturae, Carl Linnaeus described the Pisces as: [1]
Always inhabiting the waters; are swift in their motion and voracious in their appetites. They breathe by means of gills, which are generally united by a bony arch; swim by means of radiate fins, and are mostly covered over with cartilaginous scales. Besides the parts they have in common with other animals, they are furnished with a nictitant membrane, and most of them with a swim-bladder, by the contraction or dilatation of which, they can raise or sink themselves in their element at pleasure.
Linnaean Characteristics [1]
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.
Desseria is a genus of parasitic alveolates belonging the phylum Apicomplexa. The genus was described in 1995. The species in this genus were previous considered to belong to the genus Haemogregarina.
The taxonomy of the vertebrates presented by John Zachary Young in The Life of Vertebrates (1962) is a system of classification with emphasis on this group of animals.
