Researchers recently discovered harmful algae toxins in Alaskan whales, walruses, sea lions, seals, porpoises and sea otters. Their findings represent a staggering northward expansion of such toxins, although (for what it is worth) they have not yet reached concentrations harmful to human health.
Pink deep-sea worms previously represented by only a single species have puzzled biologists for nearly six decades. However, four new worms recently spotted near California and Mexico have helped scientists properly place the creatures along the evolutionary tree of life.
Ever heard of a Frogfish? Think it sounds like a made-up name? A bizarre-looking fish recently surfaced in New Zealand and is being examined by museum experts. At first glance, however, this species appears to have two legs, suggesting it may be a species of Frogfish.
Hagfish secrete a slime that researchers hope to harness and make into super hydrogels, or new super-absorbent materials that can be used in plasters and baby diapers.
Sea slugs have colorful patterns to ward off predators -- but when that doesn't work they defend themselves using toxic chemicals they gather from their environment.
Although the invasive species called Regal Damselfish may not make its way too far into the Gulf of Mexico, researchers say the Gulf's southern reefs can expect to see a lot more of these invasive fish relatively soon.
Based on current rates of ocean acidification, scientists predict oceans will be much quieter in the future -- making it more difficult for baby fish, who rely on auditory cues as a primary method of navigation, to find their way home.
In the dark polar night, when the moon appears over the horizon, things happen. That is, the huge mass of tiny marine life, or zooplankton, take on a migration in order not to be viewed by their light-seeing predators.
When a one-ton giant manta ray with a wingspan of 23 feet was caught last year in gill nets made by Peruvian fisherman, conservationists called for action. These treasured marine creatures are particularly vulnerable to overfishing and bycatch.
West Indian manatees have rebounded in Florida, prompting the U.S. Fish and Wildlife Service to downlist the species from endangered to threatened.
A dangerous fishing tactic used in Tanzania threatens local marine life. Despite laws prohibiting what's commonly known as blast fishing because explosives are involved, homemade bottle bombs are continually tossed into the sea, resulting in the deaths of hundreds of fish at a time and critical coral reefs.
Recently unearthed arthropod fossils were found to contain traces of brain fragments. Contrary to common scientific belief, the finding proves brains can withstand fossilization.
Dangerous levels of domoic acid, a naturally occurring neurotoxin from algal blooms, have been detected in Dungeness and rock crabs caught along the coast of California.
For the first time, three young giant squid were caught off the coast of Japan. This finding sheds light on the early lives of these otherwise elusive sea creatures.
