Creatures of the waters

High hydrostatic pressure and low temperatures make the deep sea a harsh environment for life forms. Actin organization and microtubules assembly, which are essential for intracellular transport and cell motility, can be disrupted by high hydrostatic pressure. High hydrostatic pressure can also damage DNA. Nucleic acids exposed to low temperatures can form secondary structures that hinder genetic information processing.

With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter.

Th ere is something about being human that instills in us a sense of wonder. When we stop to think about it, the very idea of life seems such a mystery. Where did we come from? How did life begin? When we look at the sky, we wonder about the vastness of the universe and whether other life may exist there. If we look through a microscope at a drop of pond water, we are amazed at the variety of tiny creatures we see.

When it closed its hands, horns formed of ribs and rats’ teeth stuck out of the creature’s fists, rendering them into morningstars for all intents and purposes. The horns looked sharp-edged, constructed for slashing as well as stabbing.
