Underwater Photos and Photography. Underwater
Photos, photography and facts about scuba diving on the living coral
reefs of the beautiful seas and oceans of this big blue world. Underwater
photos of some of the seas amazing marine animals, tropical fish
and sea creatures that are found in the earths oceans and on it's
living coral reefs. Photos of the colorful coral itself, did you
know that a coral reef is a living structure made up of millions
of tiny marine animals called Coral Polyps see their photos, they
are living rocks. A coral reef can be home to as many different
animal species as a tropical rainforest.
Some Coral Facts.

Big Sharks and Shark Attacks.
Well known species such as the great white sharks tiger sharks
and bull sharks and the hammerhead shark all are apex predators
at the top of the underwater food chain. Their extraordinary
skills as predators fascinate and frighten humans, even as their
survival is under serious threat from fishing and other human
activities.
Few
Sharks Attack. In 2000,
the year with the most recorded shark attacks, there were 79
shark attacks reported worldwide, 16 of them fatal. In 2005 and
2006 this number decreased to 61 and 62 respectively, while the
number of fatalities dropped to only four per year. Of these
attacks, the majority occurred in the United States (53 in 2000,
40 in 2005 and 39 in 2006).
Coral Reefs.
Most modern reefs have formed on hard surfaces
in the ocean, such as a base of an old reef that died during a period
when sea level was lower, or the edge of a rocky island. Depending
on how they start out, several types of reefs can form. Some coral
reefs form in the deep ocean and are called atolls. The theories
on how coral reefs form were first put forward by Charles Darwin
who proposed that atolls form around the edges of high volcanic
islands that gradually submerge beneath the sea with changes in
sea level or subsidence of the land.
Living Coral
Reefs. Thus an atoll starts life as a fringing reef, then
becomes more of a ring growing on the shrinking land-mass, until
the land disappears and just the coral circle remains. In some cases,
the coral growth is unable to keep pace with the sinking island,
and sunken dead reefs have been found. |
