Megalodon, the world’s largest known shark species, swam the oceans long before humans existed. Its teeth are all that’s left, and they tell a story of an apex predator that vanished.
Roaming the ancient seas eons ago, the megalodon shark eviscerated its prey with jaws that were 10 feet wide.

Protecting green turtles is difficult because they perform some of the longest migrations known in the animal kingdom.
The sound of the marine environment has been underestimated, mainly because it is not audible to the human ear.
The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.

The work of the authors reveals a world that is outward-looking, full of movement, border-crossing and south-south interconnection.
In some global fishing communities, women influence decisions, resulting in stronger claims to area-based fishing rights, improved economic returns and greater women’s empowerment.
Creating opportunities to meaningfully engage women in governance and decision-making is necessary to achieve gender equality in small-scale fisheries.
A single seagrass plant in Shark Bay is around 4,500 years old, covers 200 square kilometres of seabed, and thrives in harsh conditions.
The exploitation of marine species worsens when the fish stock is shared by countries as opposed to when it is contained within a single exclusive economic zone.
Successful management of shared fish stocks depends on countries’ collaborative efforts and adaptation to a changing world.
You may not have heard of ‘temperate mesophotic ecosystems’, but science is beginning to understand the vital role these ocean zones play – and the need to protect them.

With nine brains, blue blood and a talent for camouflage, the octopus is one of the most fascinating creatures in the sea.
Marine ecosystems across Canada’s coasts, such as eelgrass meadows that provide an important habitat for juvenile species, are threatened by human activities and climate change.
It is time to acknowledge and address the rapid shifts in Canada’s oceans. To meet this challenge, Canada’s marine conservation toolbox — starting with the Oceans Act — needs an overhaul.
