| Deep sea life can be conveniently divided into midwater,
abyssal and benthic forms. The first two categories are comprised
of creatures that seldom, if ever, experience the surface of the sea
or the bottom of the ocean, or any other surface than victim, mate
or predator. Their lives are spent in extremely calm, pitch dark and
cold conditions. Benthic forms seldom ever leave the ocean floor.
They crawl, slither, glide and burrow in even calmer, darker and colder
conditions. Most deep sea life depends directly or indirectly on a
rain of dead organic material from the sunlit waters at the surface.
Some feed directly on the material, others feed upon those who feed
upon it. A few, but as research continues it is realised ever greater
numbers of specialised animals sustain their energy needs by utilising
sulphurous-mineral-eating bacteria that thrive close to the 300 ºC
hydrothermal smoker vents, delineating the regions of tectonic split
that take place, mostly, down the centres of the great ocean basins.
Is it any wonder that these deep sea folk are amongst the oddest on
the planet? |
