Pisces in the 10th edition of Systema Naturae

In the 10th edition of Systema Naturae, Carl Linnaeus described the Pisces as: <blockquote>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.</blockquote>
