Transparency Market Research adds new "Squalene Market - Global Industry Analysis, Size, Share, Growth, Trends and Forecast, 2012 - 2018" market research report to its report store.
The vertebrate class of fish, which comprises 99 percent of all fish species, arose from a small, shell-crushing predatory fish called Fouldenia that survived a massive extinction event 359 million years ago.
Scientists have used genetic data to create a comprehensive evolutionary family tree, or phylogeny, for “spiny-rayed fish," a category that encompasses about a third of all living vertebrate species. They were quite surprised to find out just who was related to whom in the fish world.
A report just published has revealed new details on how great white sharks can make non-stop voyages that extend to 2,500 miles or more.
Named after its long whip-like tail, the thresher shark uses its eponymous feature not only to swim, but also to strike at prey.
Scientists at the Virginia Institute of Marine Science have completed a 10-year study, providing the first quantitative evidence on a bay-wide scale that the distribution and abundance of "demersal" fishes -- fish species that live and feed near the Bay bottom -- are being impacted by low-oxygen "dead zones."
When reef fish hatch from their eggs, they are immediately swept out to sea -- sometimes miles from the safety of their coral homes. Once they are able to swim, these fish must begin the arduous trek back or risk getting devoured in the open waters.
Why did animals with limbs win the race to invade land over those with fins?
Male sea lampreys, often called vampire fish, have a long ridge running across their backs that contains a long row of brown fat cells. In mammals, this fat is used to regulate body temperature.
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...
