facts

Do you know?

corals are found both in temperate and tropical waters, shallow-water reefs are formed only in a zone extending at most from 30°N to 30°S of the equator. Tropical corals do not grow at depths of over 50 m (165 ft). Temperature has less of an effect on the distribution of tropical coral, but it is generally accepted that they do not exist in waters below 18 °C. However, deep water corals can exist at greater depths and colder temperatures.

and did you know?

Coral reefs can take a variety of forms, defined in following:

Fringing reef – a reef that is directly attached to a shore or borders it with an intervening shallow channel or lagoon.
Barrier reef – a reef separated from a mainland or island shore by a deep lagoon
Patch reef – an isolated, often circular reef, usually within a lagoon or embaymt.

Apron reef – a short reef resembling a fringing reef, but more sloped; extending out and downward from a point or peninsular shore.
Bank reef – a linear or semi-circular in outline, larger than a patch reef.

Ribbon reef – a long, narrow, somewhat winding reef, usually associated with an atoll lagoon.
Atoll reef – a more or less circular or continuous barrier reef extending all the way around a lagoon without a central island.
Table reef – an isolated reef, approaching an atoll type, but without a lagoon.
