Dictionary

fish : any of numerous cold-blooded strictly aquatic craniate vertebrates that include the bony fishes and usually the cartilaginous and jawless fishes and that have typically an elongated somewhat spindle-shaped body terminating in a broad caudal (see caudal 2) fin, limbs in the form of fins when present at all, and a 2-chambered heart by which blood is sent through thoracic gills to be oxygenated — Webster

Encyclopedia

Fish are the gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term “fish” is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification. — Wikipedia

Science

Ichthyology, also known as fish science, is the branch of zoology devoted to the study of fish. This includes bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). While a large number of species have been discovered, approximately 250 new species are officially described by science each year. According to FishBase, 33,400 species of fish had been described by October 2016. — Wikipedia

    Wild populations must continuously adapt to environmental changes or risk extinction. For more than fifty years, scientists have described instances of 'rapid evolution' in specific populations as their traits (phenotypes) change in response to varying stressors. For example, Spanish clover has developed a tolerance for copper from the mine tailings in which it grows, and the horn size of Alberta bighorn sheep has decreased due to trophy hunting. But until now it hasn't been possible to reach […]

    on January 21, 2022 at 3:29 pm

    A team of researchers affiliated with several entities across Australia has found that in order to save the world's coral reefs, conservationists must also protect the corridors that connect them. In their paper published in the journal Science, the group describes their study of coral and fish larval sources and sinks and the dispersal corridors promote health and diversity in coral reefs.
