Intertidal Zone

The intertidal zone is where land meets sea. It is a challenging environment in which to live, but many species thrive here.
Mangroves

The term “mangrove” refers to a habitat comprised of a number of halophytic (salt-tolerant) plant species, of which there are more than 12 families and 50 species worldwide. Mangroves grow in intertidal or estuarine areas.
Pelagic Zone

The open ocean, or pelagic zone, is the area of the ocean outside of coastal areas, and where you’ll find some of the biggest marine life species.
Deep Sea

The deep sea includes the deepest, darkest, coldest parts of the ocean. Eighty percent of the ocean consists of waters greater than 1,000 meters in depth.
Hydrothermal Vents
Hydrothermal vents, located in the deep sea, were discovered relatively recently. It was only about 30 years ago that scientists in the submersible Alvin discovered these undersea "geysers."
