Celebrating success is great, but a new study finds patterns we can learn from — including the fact that we ignore failure at our own peril.

Successful conservation means more sharks, which is great for the health of the ocean but could also be problematic in a few important ways. Here’s how experts say we should prepare.

Big-nosed giant guitarfishes and wedgefishes are now the most endangered marine fish group. Will the international community step up to protect them from trade and exploitation?

Marine protected areas can benefit sharks and other oceanic species — but only if they’re properly established, according to a new guidebook.

These easy policy changes can save protected species from being killed by cruel fishing practices without infringing on the rights of anglers.
