Sharks and Underwater Predators.
Sharks. Well known species such as the great white
sharks, tiger sharks, 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. 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.

of Living Coral Reefs.
Coral reefs provide habitat for almost
all forms of marine life including tropical fish, crustaceans
like crabs and lobsters, seaweeds, marine animals, sea creatures,
bacteria and fungi. Coral reefs attract a diverse array
of marine life and tropical fish, each carving out its own
home, or niche. A coral reef is like an underwater city.
Little crabs dig their holes, tropical fishes find crevices
to hide in, some marine animals even live on top of other
marina animals. |
Tropical Fish.
Every inch of the reef is covered with marine
life and every form of marine life has a job to do. For
example, tropical fishes that eat seaweeds and other algae
are called herbivores, and herbivorous fishes constantly
crop the reef of fast growing seaweeds that could smother
coral polyps. This is why over fishing can kill a coral
reef, less fish mean more algae and the algae kills the
corals. Many of the bigger tropical fish such as Horse Eyed
Jacks even commute onto the reef from deeper water in search
of food. The coral reef is like Las Vegas, life is a gamble
and the city never sleeps.
