Deep-sea corals from about 400 meters off the coast of the Hawaiian Islands are much older than once believed and some may be the oldest living marine organisms known to man. Researchers have determined that two groups of Hawaiian deep-sea corals are far older than previously recorded. View the full article

The genetic toolkit animals use to build fins and limbs is the same one that controls the development of part of the gill skeleton in sharks. Also, the skeleton of any animal appendage is probably patterned by the developmental genetic program that regulates the formation of shark gills. This finding is consistent with an old theory, often discounted in textbooks, that fins and (later) limbs evolved from the gills of an extinct vertebrate. View the full article

Rising atmospheric carbon dioxide is largely responsible for recent global warming and the rise in sea levels. However scientists have found that this same increase in carbon dioxide may ironically counterbalance some of its negative effects on one of the planet's most valuable ecosystems -- wetlands.

A new report based on 40 years of data shows that birds are sending an important and troubling message about the state of the environment. The report also shows that investment in conservation works, exemplified by the remarkable recoveries of waterfowl after more than 30 million acres of wetlands were restored and managed.

These fishes are found everywhere on our shores.... east coast parkway, changi, labrador... easily caught by hand. I used to catch them while swimming on the beaches. The juvenile catfish is quite cool when young... they school and feed in a ball.... but they will get much bigger and then you have to return them back to the sea. The halfbeak will also grow quick long. Not sure about its diet but I think they will go after large zooplankton and baby fry. The monos are similar... they are fragile at this stage... they may not last too long but if they do.. they can stay with you to adulthood.

Hurdia victoria was originally described in 1912 as a crustacean-like animal. Now, researchers reveal it to be just one part of a complex and remarkable new animal that has an important story to tell about the origin of the largest group of living animals, the arthropods. View the full article

When coral colonies meet one another on the reef, they have two options: merge into a single colony or reject each other and aggressively compete for space. Marine scientists have now found a gene that may help to decide that fate. View the full article

By combining data from 48 studies of coral reefs from around the Caribbean, researchers have found that fish densities that have been stable for decades have given way to significant declines since 1995. View the full article

Somewhere out there in the ocean, SpongeBob SquarePants has a teeny-tiny cousin and a humongous uncle. That's just what one would expect from a new analysis of body sizes across all orders of animal life recently conducted by researchers. View the full article

The elephant shark, a primitive deep-sea fish that belongs to the oldest living family of jawed vertebrates, can see color much like humans can. This discovery may enhance scientists' understanding of how color vision evolved in early vertebrates over the last 450 million years of evolution. View the full article

If you kill more fish, the total population of the species declines. However, kill only small, young fish, the total number of small, young fish increases. This seemingly paradoxical conclusion has far reaching implications for the sustainable management of oceans. View the full article

The health benefits of fish consumption have been over-dramatized and have put increased pressure on wild fish, according to a new research. View the full article

Tiny creatures at the bottom of the food chain called diatoms suck up nearly a quarter of the atmosphere's carbon dioxide, yet research suggests they could become less able to "sequester" that greenhouse gas as the climate warms. The microscopic algae are a major component of plankton living in puddles, lakes and oceans. View the full article

A new study shows that detergents used to clean up spills of diesel oil actually increase its toxicity to fish, making it more harmful. View the full article

Leatherback turtles, the most widely distributed reptiles on Earth, are threatened with extinction themselves, in large part due to the carelessness of humans. A professor addresses the threat of plastics to this endangered species. Since leatherbacks prefer eating jellyfish, it's widely believed they mistake bags or other plastics for their meals.
