There's trouble brewing at the iconic Great Barrier Reef in Australia. A recent study shows that almost half of the reef, mostly in the Northern part, is practically dead while 93 percent of its corals have been bleached.
Sharks have a reputation for having large appetites, but it appears that reef sharks are remarkably light eaters. After pumping the stomachs of black-tip, white-tip and grey reef sharks, researchers found the animals eat small meals infrequently and opportunistically.
We've all heard about how noise pollution negatively impacts marine environments. But a recent study suggests that motor boats, rather than large cargo ships, easily stresses young damselfish which ultimately gives their predators the upper hand.
"Twilight zone" reef fish face numerous threats when diving deep underwater, but those with forked tails may have an advantage: they can swim quietly past predators and evade natural disasters such as cyclones and coral bleaching.
Two species of sea snakes previously thought to be extinct were recently spotted Off the coast Of Western Australia. Scientists from James Cook University suggest that there may still be time to save these species.
Even corals adapted to warmer waters, such as those living along reefs in Kimberly Australia, are particularly vulnerable to climate change and increased rates of bleaching.
