Correct Answer: 1, 2 and 3. ● The vast majority of large reefs created by corals in shallow waters (< 50 m water depth) are located within a tropical zone located between 30 º N and 30 º S latitude with a preferred temperature range of approximately 22 º to 29 º C. Coral reefs are often called the “tropical rainforests of the sea” for their astounding richness of life. ● Coral reefs are the most diverse communities on the planet. These tropical marine communities occupy less than 1% of the ocean floor, but are inhabited by at least 25% of all marine species. Scientists estimate that more than 25,000 described species from thirty-two of the world’s thirty-three animal phyla live in reef habitats – four times the number of animal phyla found in tropical rain forests.
