Latest Ichthyology Stories
Cichlid fish are more likely to accept immigrants into their group when they are under threat from predators and need reinforcements, new research shows.
Scientists from the Michigan State University made a number of improvements on a high-tech robotic fish to make it glide through the water with the greatest of ease.
Tiny coral reef wrasses can swim as fast as some of the swiftest fish in the ocean – but using only half as much energy to do so.
Chris Martin has bred more than 3,000 hybrid fish in his time as a graduate student in evolution and ecology at UC Davis, a pursuit that has helped him create one of the most comprehensive snapshots of natural selection in the wild and demonstrated a key prediction in evolutionary biology.
In search of a better shark repellant, a marine biologist stumbled upon a behavior by embryonic sharks designed to evade predators sniffing around for lunch.
Going against the flow is always a challenge, but some waterfall-climbing fish have adapted to their extreme lifestyle by using the same set of muscles for both climbing and eating.
According to a new study, as ocean predators comb the waters in search of food, they often seek out dense groups of prey to maximize their hunting efforts rather than simply areas with a large total number of prey.
New research sheds light on the nascent field of ethorobotics, the study of bioinspired robots that interact with animal counterparts.
The metabolite homarine is a useful indicator of the health status of whale sharks, according to new research from experts at the Georgia Aquarium and the Georgia Institute of Technology (Georgia Tech).

The prowfish (Zaprora silenus) is a subtropical species of a perch-like fish found in the northern Pacific Ocean. The range of the prowfish is from the Aleutian Islands, Alaska to Kamchatka, Russia, from Navarin Canyon in the Bering Sea to Hokkaido, Japan and Monterey, California. The preferred habitat of the prowish is rocky bottom at a maximum of 2,200 feet in depth where they spend most of their adult life. Prowfish can grow to a length of 40 inches or more having an elongated body that...
The Bluefish (Pomatomus saltatrix) is the only living species of the family Pomatomidae. It is a marine pelagic fish that can be found around the world in temperate and subtropical waters, except for the northern Pacific Ocean. Bluefish are known as tailor in Australia, shad on the east coast of South Africa, and elf on the west coast. Other common names regarding this fish are blue, chopper, and anchoa. It is a good eating and game fish. The bluefish is moderately proportioned with a...
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...
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...
Image Credit: WA Djatmiko/Wikipedia (CC BY-SA 3.0, 2.5, 2.0 and 1.0) The African sharptooth catfish is native throughout Africa, and the Middle East, and in the 1980’s it was introduced all over the world. This catfish lives on muddy bottoms in freshwater lakes, rivers, swamps, man-made habitats, and occasionally found in urban sewage systems. This species is able to crawl across dry ground to another body of water when one pool dries up. It is also able to survive for long periods of...
