What is a dead zone? Hypoxic zones are areas in the ocean of such low oxygen concentration that animal life suffocates and dies, and as a result are sometimes called dead zones.. One of the largest dead zones forms in the Gulf of Mexico every spring.

The area underneath the pelagic zone is called the benthic zone, or deep-sea, and is host to silt, sand, and slowly decomposing organisms. Edit. Share to: 1  5 Cancun, Mexico Beaches to Visit Cancun, Mexico is a mecca for travelers searching for relaxation under the sun.
