A new study on the schooling habits of fish could provide new insights into the social behaviors and natural variations of humans.
Fish fossils that are about 23 million years old give unprecedented insight into the evolutionary history of the gobioid order, one of the most species-rich groups among the modern bony fishes.
An unusual fossil fish that has fins behind its anus could have implications for human evolution according to a scientist at The University of Manchester.
Officials are looking for a high-tech apparatus that will help an injured loggerhead turtle regain the ability to swim after she lost both front flippers.
The earbones, or 'otoliths', help fish to detect movement and to orient themselves in the water. Otoliths set down annual growth rings that can be measured and counted to estimate the age and growth rates of fish.
"Sound vibrations are transmitted to the inner ear via anterior extensions of the swim bladder or via bony ossicles", the biologist Tanja Schulz-Mirbach explains how swim bladders may serve for hearing.
The rise of ocean infrastructure development to tap energy sources such as tides, offshore wind and natural gas will require more pile driving, the practice of pounding long, hollow steel pipes called piles into the ocean floor to support energy turbines and other structures.

Balistidae is a family that contains about forty species of triggerfish that can be found in tropical and subtropical waters around the world, although the greatest variety of species can be found in the Indo- Pacific region. Most triggerfish species can be found in shallow water in coastal areas, especially near coral reefs, although some can be found living in the open ocean. While some species are edible, like the grey triggerfish others are not recommended for human consumption, including...
The Asian Arowana (Scleropages formosus) comprises several phenotypic varieties of freshwater fish that are distributed geographically across Southeast Asia. As they are native to Southeast Asia, Asian Arowana inhabits blackwater rivers and slow moving water flowing through the forested swamps and wetlands. The adults feed on other fish while the juveniles feed on insects. These popular aquarium fish have special cultural importance in areas that are influenced by the Chinese culture....
The Butler’s Frogfish (Tathicarpus butleri), known also as the blackspot anglerfish, is a rare species of frogfish belonging to the family Antennariidae. The only member of its genus, this species is the most derived member of its family, representing a separate lineage from all other frogfishes, leading to some consideration of it being placed in its own family. It can be found off the southern coast of New Guinea, and along the coasts of Western Australia, the Northern Territory, and...
The psychedelic frogfish is found only around Ambon Island, Indonesia at depths of 16 - 23 feet in coral rubble about 66 feet from the shoreline. This fish was discovered in 1992 amongst a shipment of assorted fish that was delivered to the Dallas Aquarium at Fair Park. But was not observed or photographed in the wild until 2008. The psychedelic frogfish was named one of the top ten new species discovered in 2009 by Arizona State University's International Institute for Species Exploration...
The little tunny is found widespread in temperate and tropical waters of the Atlantic Ocean, Black Sea and Mediterranean Sea. It is the most common tuna and is highly migratory, with a range from Cape Cod, Massachusetts to Brazil in the Western Atlantic. In the Eastern Atlantic it is found from Skagerrak to South Africa. The little tunny will form schools close to the shoreline, around inlets, and sandbars that can cover up to two miles. This fish prefers warm water and will migrate south in...
