A distinctive 200-million-year-old fish used a combination of jutting front teeth and pebble-shaped rear teeth to feed on bivalves and other hard-shelled creatures it could find from the sea floor, according to new research from the University of Bristol.
In dark or murky waters, fish are still able to navigate their environment thanks to a network of body sensors that detect changes in the water flow around them.
While the fossil record has found that wrists and fingers have an aquatic origin, previous attempts to link fingers and fins have proven unsuccessful. Now, though, a team led by University of Chicago researchers has discovered the reason why: scientists were studying the wrong fish.
A new study from Vanderbilt University shows that the electric eel’s electroshock system bears a remarkable resemblance to a Taser.
Despite extensive measures to protect the Baltic Sea from anthropogenic activities since the late 1980s, oxygen concentrations continue to decrease. Rising temperatures in the bottom water layers could be the reason for the oxygen decline.
Paleontologists from the University of Zurich now reveal that climate catastrophes in the past played a crucial role in the dominance of ray-finned fish today.
Today, NOAA released the 2013 edition of their annual report, Fisheries of the United States, and five of the nation’s top ten ports for landings volume are anchored by the commercial menhaden
Recreational fishermen prize large trophy fish. Commercial fishing gear targets big fish. After all, larger fish feed the egos of humans as well as their bellies.
Understanding how viruses attack giant algal blooms may help us understand their role in fixing global carbon.

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...
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.

Synaptula lamperti is a species of sea cucumber that can be found in the waters of the Indo-Pacific. Its range includes the coastal waters of Papua New Guinea, the Philippines, Indonesia, and Micronesia. It does not have the tube feet, which are common to other species of sea cucumber, instead moving around by using a small grouping of pinnate feeding tentacles, which are always moving. It can also move by using the small, hook-like bones found along its body, attaching itself to the sea...
Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...
Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...
