Deep-sea corals and sponges are some of the oldest animals on Earth, living for hundreds of years at depths beyond direct human observation. Coral, sponge, and fish communities thrive in the cold, deep waters off California’s coast, but are rarely – if ever – visited or observed.
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.
In an office up a steep hill in a seaside suburb of Athens, a tiny blue light flickers from a computer terminal. Dr Alexandros Frantzis, Greece’s foremost oceanographer, points it out. The light, he says, tracks marine traffic “in real time”.
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.
Lionfish are decimating valuable native species in the western Atlantic Ocean, but spearing the predators hasn’t been enough to slow their spread. Now scientists and fishers are developing traps and other technology to catch the voracious fish en masse.
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
Scientists worry that the humpbacks may have been forced elsewhere in a search for food as the seas grow rapidly warmer and their feeding grounds are disturbed.
For years, scientists have disagreed about which species of baleen whale came first, and how the toothless species were related.
