We hear a lot about how humans eating meat is bad for the planet. But if every animal only ate plants, Earth would look dramatically different.
A species that is an “apex” predator in one environment won’t necessarily remain so in another.
Megalodon would have dwarfed today’s great white sharks.

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.

As authorities grapple with the best way to respond to the tragedy, it’s worth remembering all shark mitigation measures come with both merits and drawbacks – and none is a silver bullet.
The Liopleurodon was a pliosaur of the Jurassic period.
The fossil of a gigantic ichthyosaur was recently discovered in the UK. It wasn’t the only creature lurking in the Jurassic oceans.
Looking a bit like enlarged woodlice, ancient trilobites crawled along the seabed and had an exoskeleton made of calcite — nature’s version of a suit of armour.
Won’t you be my neighbor?

For the first time in the US, a ballot measure will ask voters whether to restore wolves to a place where they’ve been eradicated. Coloradans have strong views on both sides.
Are cats really to blame for the worldwide loss of biodiversity?

Framing cats as responsible for declines in biodiversity is based on faulty scientific logic and fails to account for the real culprit – human activity.
King Penguins at sea.
This study provides the first evidence that penguins emit sounds underwater when they hunt.
Some predators, including red foxes, move into burnt areas after fires pass through.
Some predators thrive after fires, other wilt – and one bird even starts them on purpose.
Naya was a mother to the first Belgian-born cubs in over a century. All are now thought to be dead.

Europe is getting wilder as more people live in cities, but Naya’s death shows this trend may have limits.
Eastern quolls have been introduced in Booderee Nation Park as part of a rewilding project.
Rewilding is gaining popularity around the world, as a means to restore ecosystems to their ancient state. But just like Vegemite, Australian rewilding projects need to have a unique flavour.
Warning sign at a Cape Cod beach.
The return of white sharks to Cape Cod, Massachusetts was a tourism success story – until a shark killed a swimmer. Can the Cape’s residents and visitors learn to share the ocean with these apex predators?
Livestock guardian dog breeds, such as Maremma, are often raised with and trained to consider themselves part of a livestock herd and so protect their herd from threats.
All three of the methods found to be most effective at protecting livestock do not involve killing carnivores.
Whoosa vicious helpful predator? You are! Yes you are!
Dingoes increase cattle yields, mountain lions reduce car crashes and vultures eat organic waste: like them or not, predators help humans.

If sharks habitats aren’t known, it’s harder to conserve either the animals or those habitats.
Dolphins contribute important knowledge about ocean health.
Marine mammals are often referred to as sentinels of the ocean and research on whales and dolphins in particular contributes important knowledge about the health of our seas.
Dingoes can help manage devastating red fox and feral cat numbers, but only if we let enough of them live in key areas.
Dingoes and wolves can help control destructive smaller predators, new research shows, but only if we encourage them across wide areas.
Predators like the cougar can spread seeds from consuming birds which eat the seeds.
Carnivorous predators play an important, and until now unknown, role in preserving plant populations in the territories they inhabit.
Just don’t say so to his face.
Declining numbers mean the continent’s top predator isn’t fulfilling its ecological role.
