New research finds that deaths caused by human activities are not just impacting individual North Atlantic right whales and their immediate family units, but actually impeding population growth and recovery of the species, which has been declining since 2010.
Mesophotic reefs reside, by definition, at depths of 30 to 150 meters (100 to 500 feet). They support a variety of fish and species of soft corals like this one in Palau in the western Pacific.
In some areas, killer whales feed primarily on sea mammals and big fish like tuna and sharks and are then threatened by PCBs. In areas where the killer whales primarily feed on small fish like herring, they are less threatened.
Just 30 of the prehistoric fish known to exist, raising fears oil wells will push it to extinction
There are more than 500 known species of sharks the world — most of them you’ve probably never heard of. In fact, almost 16 percent of all sharks are threatened with extinction (ranked as Vulnerable or higher by the IUCN).
The whale shark is the largest fish in the world, but much of its lifecycle remains shrouded in mystery. These gentle giants gather in just a handful of places around the globe – something which has long baffled scientists – but our new research has started to explain why.
Researchers hope tagging efforts will yield new insights into mantas’ life cycle and behavior, including their migration from what could be the first confirmed nursery for juveniles in the Gulf of Mexico.
The future of krill – and all the marine wildlife that feed on them – is uncertain in the changing Southern Ocean. Krill biologist Stephen Nicol says they may be adaptable to climate change, but new technologies need to be deployed to study their enigmatic behavior.
Forget ‘Spidey sense’ – the seafloor-dwelling mantis shrimp can perceive light and colors invisible to humans. Scientists are investigating its complex and utterly bizarre vision system and how it could help create advanced underwater cameras, medical devices and robots.
Removing a thick fishing rope from a highly fertile whale’s jaw was a priority for scientists who fear the species may be in terminal decline
