Reefs are the big cities of the sea. They exist because the growth of corals matches or exceeds the death of corals – think of it as a race between the construction cranes (new coral skeleton) and the wrecking balls (the organisms that kill coral and chew their skeletons into sand).
19 paź 2023 · Coral reefs are important ocean habitats and offer a compelling case of the risks of climate change. Reefs provide a large fraction of Earth’s biodiversity —they have been called “the rain forests of the seas.”
A coral reef is a structure in shallow ocean areas that is formed mainly by stonelike coral skeletons. Corals are small marine animals that live in all oceans of the world. Some individual corals, called polyps, are colonial, which means they grow together in large groups called colonies. As they die, they leave behind their skeletons.
Coral reefs are known as the “rainforests of the sea.” They cover less than one percent of Earth’s surface, but are home to one quarter of known marine fish species. Scientists estimate that there are one to eight million undiscovered species living in and around the reef.
