Benthic Habitats Keychain

$33.75

Product Description

mini-benthic-environments.pngIn 1977, the research submersible Alvin descended to investigate geological activity deep beneath the the Pacific Ocean, and what it found was completely unexpected! Rather than a barren expanse, scientists saw a dense and thriving community of living organisms. This discovery of life, which got its energy not from the Sun, but from the heat of the Earth's core was a revolution in biology.

This keychain depicts a variety of habitats and organisms from the world-girdling network of deep sea (benthic) communities that continues to astonish explorers. The isolation of these oases of life in the abyss has resulted in enormous diversity. Otherworldly tube-worms cling to the sides of hydrothermal vents. Fields of mussels surround dense pools of brine. These, and many others defy extremes of heat, cold, salinity and pressure to flourish in the deep.

The two halves of this keychain can be opened, showing a cutaway section of these habitats. Arrows depict the circulation of super-heated water around the vents, and deposits of metal-rich mud are also shown. Comes with a detailed explanatory diagram. A unique educational accessory for aspiring explorers!
