In the 10th edition of Systema Naturae, Carl Linnaeus described the Pisces as:
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.
Cardiocephaloides longicollis is a species of flukes. The life cycle of C. longicollis is asexual as well as complex. Its asexual stage resides in the body of whelks where it replicates many times, and eventually its eggs are dispersed in the water through feces. C.longicollis begin their early life as free swimming miracidia larvae in the water. They go on to infect snails, and a variety of fishes, usually second intermediate host, in the form of a cercariae. While C.longicollis has previously been recorded in 19 fish species, researchers have found 12 other species which are viable hosts for C.longicollis making for a grand total of 31 aquatic species. The final host for this parasite are the gulls that eat the infected fish in which the parasite has formed cysts in.
