Scientists from Conservation International have discovered a new species of shark living in the waters of Indonesia. Unlike other sharks, however, this species has an unusual way of getting around; it walks.
Scientists now say that if fish larvae were lost, they could just sniff their way back home, following the smell of the coral reefs.
There’s no “Google Maps” for finding fish. The radio signals that are the backbone of traditional GPS cannot pass through seawater. But sound travels remarkably well, so scientists often use acoustic telemetry to estimate an individual fish’s location.
Small prey fish can grow a bigger ‘eye’ on their rear fins as a way of distracting predators and dramatically boosting their chances of survival.
Every year, thousands of tourists bring home colorful restaurant menus from Hawaii. These souvenirs hold more than just happy memories; they also contain valuable data that allows researchers to track long-term changes to important fisheries in the state.
Objective: To capture, tag, study and release 10-20 mature sharks for research and public safety over 30 days, in collaboration with top research institutions. CAPE
The latest blog from PortNoise.com Magazine, a Marble Media LLC online publication, offers a disturbing picture of the rampant spread of the non-native lion fish in the Atlantic Ocean.
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.
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...

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...

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...
