The next time you pry a clamshell or crack a lobster claw for dinner, pay a small homage. For many ocean creatures with hard shells, growing that armor is taking more effort than ever. Find out why.

Scott Goetz has studied the boreal forest of Alaska for more than two decades, but year by year, the landscape is becoming less familiar to him. See how climate change is affecting the forest — and how the forest, in turn, may be influencing climate.

Just like we have official wilderness areas on land, some people think we need them in the marine realm. Consider the need for vast stretches of coral reefs, underwater lawns of seagrass, and miles of open ocean.

Fishing supports residents all over the 700 Bahamian islands, but even more so in the less-accessible “Out Islands” like the Exumas. What does it mean for locals when their home becomes a "no-take" marine protected area? Find out.

The bulk of fishing income in The Bahamas is brought in by three species: the Nassau grouper, the queen conch, and the Caribbean spiny lobster. Find out how these overfished species are maintaining a foothold in The Bahamas.

Discover what this contributor to the Bahamas Biocomplexity Project knows about corals, conchs, and their spawn…and why genetics matters in marine reserves.

Find out why this huge shoal between Massachusetts' Cape Cod and Nova Scotia's Cape Sable Island is one of the world's most important fishing resources — and why it's now at risk.

Water bodies on our planet form a network, which aquatic species migrate over evolutionary time as needed or by accident. Find out how Homo sapiens have dramatically changed and accelerated this process.

Meet a deep-sea ecologist at the Monterey Bay Aquarium Research Institute who has pioneered the use of submersible robots to study jellyfish and other gelatinous invertebrates in their native deep-sea environment.

Only in recent years have marine biologists come to grasp the astonishing abundance of gelatinous animals in the world's waters. Discover how that knowledge is helping them better understand how ocean food webs work.
