Marine wildlife rarely remain in one habitat. Most species rely on a healthy network of ecosystems to raise their young and catch their food.

Sexual reproduction helps keep coral colonies diverse and resilient. Now, scientists are doing it in a lab to restock flagging reefs.

Hundreds of organizations are working around the world to restore damaged coral reefs. New research shows that rapid ocean warming threatens these efforts.

A new study of shark populations in 58 countries around the world detected none in almost 20% of the locations surveyed.
