Manitoba has released a plan to preserve the world's largest beluga population while numbers remain abundant. "We have a healthy population, but the environment is changing," said Manitoba Conservation Minister Tom Nevakshonoff. "It's a rare opportunity when you can take something that's not in distress and focus on it now to preserve that rather than doing damage control.

In contrast to what was previously thought rather than seeing a gradual build-up of waves, the rogue wave will come seemingly out of nowhere.

New research from the University of Oxford in collaboration with the University of Western Australia shows that the anecdotal evidence heard from mariners describing "walls of water" coming at them in the open ocean may not be so far from the truth.

In my article Open Season on US Coastal Sharks, I asked readers to write to each and every member of the Florida Fish & Wildlife Conservation (FWC) Commission.

The San Jose was carrying gold, silver, gems and jewellery collected in the South American colonies to be shipped to Spain's king to help finance his war of succession against the British when it was sunk in June 1708 during heavy fighting off the coast of Cartagena. In the fighting the vessel was reported to have exploded, with most of its crew killed.

Sharks home in on faint bioelectric fields generated by the bodies of their prey which they pick up using sensitive detectors on their snouts.

When researchers from Duke University showed captive cuttlefish held in tank videos depicting the menacing silhouettes of a shark or predatory grouper fish they reacted by lowering the electric field dramatically. Being shown the shadow of a harmless crab produced no reaction.

A team of researchers from the University of Michigan focused on leatherback sea turtles nesting on St. Kitts, an island in the West Indies southeast of Puerto Rico. The team wanted to know what factors influence where and when the leatherbacks lay their eggs.

It has been suggested that characteristics of the sand, the slope of the beach and proximity to vegetation contribute to the success or failure of nests, but which factors cause female leatherback sea turtles to dig a nest in a particular spot has never been investigated.

With up to 10m tides, the Kimberley region in north Western Australia has the largest tropical tides in the world, creating naturally extreme and highly dynamic coastal habitats that corals from more typical reefs could not survive.

Researchers at the University of Western Australia's Oceans Institute were thus surprised to find that corals from the region are just as sensitive to heat stress and bleaching as their counterparts from less extreme environments elsewhere.

Satellite telemetry suggests that seamounts represent an overlooked cryptic habitat for humpback whales

Seamounts probably serve multiple and important roles as breeding locations, resting areas, navigational landmarks or even supplemental feeding grounds for this species, which can be viewed as a transient component of the seamount communities.
