Ichthyology is the study of fish that focuses on many types of fish including cartilaginous fish, jawless fish, and skeletal fish. This branch of zoology can be associated with marine biology and fisheries science, as well as other areas of study. Ichthyologists, those who practice ichthyology, have discovered more than 32,200 species of fish, and it is thought that they discover 250 new species each year. Humans first began to study fish during the Upper Paleolithic Revolution, when humans...
