As the world gets hotter, fish are getting smaller. The future of aquatic ecosystems – and fisheries – could depend on understanding how and why it’s happening.
From fluffy crabs that wear sea sponge hats to worms that glow in the dark, scientists are constantly finding amazing new life forms in the ocean.
As toxic water continues to spill from tailings ponds across mining developments, decades of scientific research provides evidence of how wildlife will be affected.
The snailfish was recently found living at depths believed physically impossible.
Raw seafood dishes such as sushi, poke bowls and ceviche are increasingly popular, but can harbour fish-borne parasites. What’s the best way to protect ourselves?
Putting a dollar value on nature has staunch opponents who say it’s morally wrong, but without it, building dams and other infrastructure can run roughshod over vital ecosystems.
Food quality, not just quantity, matters when it comes to the health and survival of the southern resident killer whales.
Antioxidants in salmon’s diet give the fish their distinctive colour, but internet rumours proliferate about how farmed salmon achieve the same colour.
We can trace our human evolutionary lineage back to fish.
Over 100 shark and ray species were recently added to an international treaty, known as the CITES list, to protect them from the threat of unsustainable and illegal trade.
By washing our clothes, we release microfibres into the environment which are then ingested by marine animals.
Pam Longobardi collects and documents ocean plastic waste and transforms it into public art and photography. Her work makes statements about consumption, globalism and conservation.
