Desert WildlifeI live in the desert. It's hot, dry, and always sunny. It's known for scorpions and prickly cactus. But it's also known for some pretty cool animals and birds...

"Dead Zones are huge swaths of deep ocean that are ultra-polluted and oxygen starved. Unable to breathe in Dead Zones, most sea creatures, such as fish and shellfish, either flee or die. But jellyfish thrive in Dead Zones. How? By playing unique metabolic tricks.
For example, jellyfish can dissolve oxygen in their watery tissues, and thereby carry built-in, life-sustaining oxygen supplies into Dead Zones. (Jellyfish are 95 percent water; humans are 65 percent water.)
Moreover, jellyfish in Dead Zones face few predators and competitors that would otherwise control their numbers. Feasting on ubiquitous plankton, jellyfish not only survive but actually dominate many Dead Zones.
The Earth currently has more than 400 Dead Zones--some of which cover tens of thousands of square miles. Many Dead Zones are so jellified that they could rightly be renamed Jellyfish Zones. The U.S. has Dead Zones in the Gulf of Mexico, the Chesapeake Bay, Narragansett Bay, Long Island Sound and the Pacific Ocean off the Oregon coast." - National Science Foundation
