Introduction
Ichthyology (from Greek: ἰχθύς, ikhthus, "fish"; and λόγος, logos, "study") is the branch of zoology devoted to the study of fish. This includes skeletal fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). While a majority of species have probably been discovered and described, approximately 250 new species are officially described by science each year. According to FishBase, 31,500 species of fish had been described by January 2010.[1] There are more fish species than the combined total of all other vertebrates: mammals, amphibians, reptiles and birds.
Break Down of this Directory Area will be to provide Online Information about species and the biological classification of both Fresh Water and Marine Fish Throughout the World. There will be also links set up to books in the book section of this website.
