what is the low temperature in the coral reef
Low temperature limits for reef and coral growth It has been known for decades that reefs do not form where the ocean temperature regularly goes below 18Â°C for intervals of weeks to months. Reef geologists concerned with the history of reefs refer to this well-established fact, yet in so-doing they often assume that lower temperatures kill corals. This is seldom the case. Reef-building allows entire ecosystems to exist, a process that can only happen if the growth of macro-algae is held in check.
