Rebel Coelacanth Discovery Forces Rethink On Their Evolution
2012-05-03 09:21:49

Canadian researchers have discovered a new species of Triassic coelacanth, a fish presumed extinct until a population was found off the coast of Africa in the 1930s, while digging through a trove of museum fossils, reports Jennifer Viegas for Discovery News. The coelacanth (pronounced SEE-la-kanth) is a primitive, slow-moving fish that is often referred to as a living fossil because it has existed largely unchanged for more than 300 million years. But the new discovery, dubbed Rebellatrix,...

Smalleye Pigmy Sharks Get Their Glow On For Camouflage
2012-04-27 04:40:45

Jason Farmer for RedOrbit.com There are a number of sharks that have specialized light-emitting organs on their undersides that allow them to glow in the darkest depths of the ocean. In fact, according to researchers, at least 10% of all known shark species are luminous, and this ability is one of the most mysterious areas of shark biology. A new study of a tiny predator known as the Smalleye pygmy shark (Squalious aliae), led by Dr Julien Claes from the Catholic University of Louvain...

Team of female scientists develop sophisticated numerical model to study larval behavior, fill ecological gap The behavior of marine larvae is central to fully understanding and modeling the pelagic (open ocean) stage for many coastal organisms. For the first time, a numerical study conducted by the University of Miami (UM) incorporates horizontal larval fish navigation skills into realistic 3D flow fields, creating a powerful tool that spells out how larvae use environmental cues to find...

A task force that conducted one of the most comprehensive analyses of global “forage fish” populations issued its report this week, which strongly recommends implementing more conservative catch limits for these crucial prey species. The Lenfest Forage Fish Task Force calls for the harvest reduction of sardines, anchovies and other forage fish so that they can continue to serve as critical prey for larger species, including salmon, cod and tuna, as well as for dolphins, whales,...

Forage fish twice as valuable in the water as in the net Fishing for herring, anchovy, and other "forage fish" in general should be cut in half globally to account for their critical role as food for larger species, recommends an expert group of marine scientists in a report released today. The Lenfest Forage Fish Task Force conducted the most comprehensive worldwide analysis of the science and management of forage fish populations to date. Its report, "Little Fish, Big Impact: Managing a...

University of Rhode Island marine biologist Jacqueline Webb gets an occasional strange look when she brings fish to the Orthopedics Research Lab at Rhode Island Hospital. While the facility's microCT scanner is typically used to study bone density and diseases like osteoporosis, it is also providing new insights into the skull structure and sensory systems of fish. A professor of biological sciences and director of the marine biology program at URI, Webb studies the lateral line system, 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...

Little tunny, Euthynnus alletteratus
2013-03-28 14:07:39

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...
