SeaWorld's new CEO made a shocking announcement today about the future of its entertainment and breeding programs for killer whales. But what does that really mean for the future of its animals in captivity?

The endless cascade of nutritional information—about localism, vegetarianism, veganism, organic food, the environmental impact of eating meat, poultry, or fish, and more—makes the simple goal of a healthy, sustainable diet seem hopelessly complex. We talked to scientists, chefs, and farmers to get the ultimate rundown on how you should fuel up.

The oceans are in serious trouble, creating a tough question for consumers: Should I eat wild fish, farmed fish, or no fish at all? The author, a longtime student of marine environments, dove into an amazing new world of ethical harvesters, renegade farmers, and problem-solving scientists. The result: your guide to sustainably enjoying nature's finest source of protein.

It's time for their doors to be shut once and for all

The hours are long, and the work can be dangerous.

Dolphins communicate with each other, but can they communicate with us? Marine biologist Denise Herzing is drawing on decades of research, a vast digital library of whistles and clicks, and new computer wizardry designed to bridge the species gap. Tim Zimmermann goes deep with one of history's grandest experiments.

With the OSHA trial on trainer safety at SeaWorld Orlando starting September 19, Tim Zimmermann asks: Should Martínez’s death have served as a warning about the lethal potential of killer whales being trained for our entertainment?

After Marine Corps Veteran Ronnie Simpson survived an explosion in Iraq in 2004, he threw himself at an audacious goal: to sail around the world. It almost killed him.

It swims at 20 miles per hour and can carve out hunks of human flesh. It's one of eeriest beasts in the ocean—it's the Humboldt Squid.
