If fish and coral larvae opt to settle in coral-dominated areas instead of the degraded, seaweed-dominated reefs ecologists' efforts to restore reefs could become complicated.
Read moreAs I learned where and how to look for the local sharks, I focused on blackfin reef sharks (Carcharhinus melanopterus), because they were so easy to find patrolling the shores.
Read moreAccording to a new study, the yellow-bellied sea snake (Hydrophis platurus) can dehydrate for several months before reconstituting itself after heavy rains.
Read moreIn experiments, juvenile damselfish in dead corals displayed risk-prone behaviours, sitting further away and higher up on the reef patch, and failed to respond to predation cues, compared to those on live coral patches.
Read moreUsing a camera-based tracking software system, the researchers compared a control group of rockfish kept in normal seawater to another group in waters with elevated acidity levels matching those projected for the end of the century.
Read moreThis feeding mode involves rapid movement to overcome prey escape capabilities and only functions only at short range.
Read moreIn order to show people the true nature of sharks on his dives, Jim specifically targeted those with the worst reputations. He was the first eco-tourism guide operator to do so.
Read moreSharks have a very different set of senses than we do, yet the eyesight of the free swimming species is good, so when they look at you, they are seeing you.
Read moreIn a new study, scientists have revealed the diving behaviour of sharks appears to be influenced by the moon, water temperature and time of day.
Read moreThis changes their camouflage so that they are very well camouflaged against the yellow sand during the day, and dark at night - we think to blend in with shadows on the beach.
Individuals did not change colour when put into dark conditions, but they did become brighter when placed on a white versus a black substrate. Our findings show that ghost crabs have a circadian rhythm of colour change mediating camouflage, which is fine-tuned by adaptation to the background brightness.
Read moreThe researchers found that Stingray City's stingrays show distinctly different patterns of activity than their wild counterparts, who don't enjoy daily feedings or close human contact.
Read moreUS researchers measured and compared the net dark oxygen uptake of fish–anemone pairs when partners were separate from each other, together as a unit, and together as a unit but separated by a mesh screen that prevented physical contact.
Read moreA team from the Universities of Bristol and Exeter exposed crabs to recordings of ship noise and found it affected their metabolism—indicating elevated stress—and found little evidence that crabs acclimatise to noise over time.

Read moreThe evidence came from a task-based experiment with juvenile sharks conducted in an underwater pen.
Read moreIn a study that covered 17 separate locations round Lizard Island in far North Queensland, researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University videoed the behaviour of large reef fish, allowing them to ide
