White sharks are top predators in the marine environment, but unlike their terrestrial counterparts, very little is known about their predatory activity underwater, with current knowledge limited to surface predation events. Now, a team of international scientists has used video- and data-logging technology to shed new light on predator-prey interactions of these mighty sea creatures.

Read moreScientists have found that global tuna catches have increased over 1,000 per cent in the past six decades, fueled by a massive expansion of industrial fisheries.
Read moreAn in-depth look at Australia's Great Barrier Reef over the past 91 years concludes that since 1928 intertidal communities have experienced major phase-shifts as a result of local and global environmental change, leaving few signs that reefs will return to their initial state in the near future. The long-term implications of these changes highlight the importance of avoiding phase shifts in coral reefs which may take many decades to repair, if at all.

Read morePopulations suffering from malnutrition have the nutrition they need right at their doorstep — in the form of fish. However, a complex picture of illegal fishing and trade in seafood gets in the way.
Read moreScientists have seen for the first time how corals collaborate with other microscopic life to build and grow.
Read moreSea urchins have five teeth, each held by a separate jaw in a circular arrangement at the center of their spiked, spherical bodies. Now, researchers have discovered how the teeth of the pink sea urchin are specially equipped to sharpen themselves.
Read moreWhen it comes to feeding, corals have a few tricks up their sleeve. Most of their nutrients come from microscopic algae living inside of them, but if those algae aren't creating enough sustenance, corals can use their tentacles to grab and eat tiny prey swimming nearby.
