Marine Biology for the Diver: What You Should Know

Every distinguished diver is, at heart, a connoisseur of marine biology. Understanding deepens pleasure and enhances protection.

Marine food chains

The sea operates on a hierarchical system: plankton feed the smaller fish, which feed the larger fish, which feed the larger ones. Any defect at any level reflects on the whole.

Great Adaptations

Camouflage
One of the most innovative mechanisms of evolution. Animals that are well matched to their environment live longer and hunt more. Octopus, squid, and paperfish are all amazing examples.

Biological light
In the depths of the sea, where sunlight cannot reach, organisms produce their own light using biochemical reactions.

Marine reproduction

Many fish secrete their eggs into the water and leave them to their fate. Others, like sharks, give birth to live young. Turtles return to their birth beach after decades to lay their eggs.

Maritime Migrations

The blue whale migrates thousands of kilometers between feeding and breeding. Small fish migrate in ocean eddies called eddy currents.
