| Ichthyology (from Greek: ἰχθυ, ikhthu, "fish"; and λόγος, logos, "knowledge") is the branch of zoology devoted to the study of fish. This includes skeletal fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). An estimated 25,000 fish species exist, comprising a majority of vertebrates. While a majority of species have probably been discovered and described, approximately 250 new species are officially described by science each year. The practice of ichthyology is associated with marine biology and limnology. | ||
