History

Evolutionarily, the genus has demonstrated significant resilience, though current anthropogenic stressors are outpacing their natural adaptation rates.

Examples

The genus includes over 100 species, ranging from the critically endangered Acropora palmata (Elkhorn coral) to the widespread Acropora millepora.

Overview

Characterized by their high growth rates and morphological plasticity, Acropora species are the most diverse and widespread reef-building corals globally.

Importance

They are critical for coastal protection, as their complex structures dissipate wave energy, preventing coastal erosion and protecting shoreline habitats.

How It Works

Acropora utilize calcification to secrete calcium carbonate skeletons. Their survival is heavily dependent on the health of their endosymbiotic dinoflagellates (zooxanthellae).

Frequently Asked Questions

Why are Acropora important for the ocean?+

Acropora are the most important builders of coral reefs. They provide a home for many marine animals and help keep the ocean healthy.

How do Acropora help make coral reefs?+

Acropora grow in many pieces that stick together, forming the big, hard structure of a reef. This structure gives space for fish and other sea creatures to live.

Where can you find Acropora?+

Acropora grow in warm, clear waters around the world, especially in places with coral reefs.

What does Acropora look like?+
