10th edition of Systema Naturae
The 10th edition of Systema Naturae (Latin; the English title is A General System of Nature) 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.
Their external and internal structure; their comparative anatomy, habits, instincts, and various relations to each other, are detailed in authors who professedly treat on their subjects.
These classes were ultimately created by studying the internal anatomy, as seen in his key:[3] By current standards Pisces and Vermes are informal groupings, Insecta also contained arachnids and crustaceans, and one order of Amphibia comprised sharks, lampreys, and sturgeons.
They are areal, vocal, swift and light, and destitute of external ears, lips, teeth, scrotum, womb, bladder, epiglottis, corpus callosum and its arch, and diaphragm.
"[3] Linnaeus divided the birds based upon the characters of the bill and feet, into the following 6 orders and 63 genera: Linnaeus described his "Amphibia" (comprising reptiles and amphibians) as: "Animals that are distinguished by a body cold and generally naked; stern and expressive countenance; harsh voice; mostly lurid color; filthy odor; a few are furnished with a horrid poison; all have cartilaginous bones, slow circulation, exquisite sight and hearing, large pulmonary vessels, lobate liver, oblong thick stomach, and cystic, hepatic, and pancreatic ducts: they are deficient in diaphragm, do not transpire (sweat), can live a long time without food, are tenacious of life, and have the power of reproducing parts which have been destroyed or lost; some undergo a metamorphosis; some cast (shed) their skin; some appear to live promiscuously on land or in the water, and some are torpid during the winter.
"[3] Linnaeus divided the fishes based upon the position of the ventral and pectoral fins, into the following orders and genera:[3] Linnaeus described his "Insecta" (comprising all arthropods, including insects, crustaceans, arachnids and others) 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 (or horns), which project from the head, and are the probable instruments of sensation.
By the Ancients they were not improperly called imperfect animals, as being destitute of ears, nose, head, eyes and legs; and are therefore totally distinct from Insects.
