The Hawaiian islands are home to over 400,000 acres of magnificent, colorful coral reefs. Apart from being beautiful to behold during snorkeling tours, they play an integral role in providing habitats for fish and protecting the shoreline from erosion. Here are some other fascinating facts about the coral reefs of Hawaii. 

4 Facts About Hawaiian Coral Reefs

1. They’re Unique

Thriving in the Hawaiian archipelago’s subtropical climate and geographical isolation, new species have evolved throughout the course of history. These coral reefs foster an extremely biodiverse ecosystem that is home to over 1,250 unique species of marine life. Over 25% of all aquatic fish and plants are endemic to Hawaii’s coral reefs. 

2. They Facilitate Algae Growth

Algae is responsible for the vast majority of oxygen production on the planet, even more than all land foliage combined. At least 500 species of marine algae originate in Hawaii’s coral reefs and waters. They provide food and shelter for marine animals. Some species, such as coralline algae, create sand for beaches.

3. They’re Vulnerable  

Coral reefs are delicate and sensitive to sediment, nutrient, and chemical contaminants. Certain toxins may cause algae to grow out of control and smother the reefs. Pollution results in dangerous coral diseases, and climate change contributes to coral bleaching and calcifying. 

4. Protection Is Key

Fortunately, you can minimize damage to coral reefs in several ways. When you go on your next snorkeling tour, be careful not to touch, stand, or walk on the reefs. Don’t feed the fish since doing so throws symbiotic ecosystems out of balance. Every day, discard your trash and recycling in designated bins so they don’t end up in the ocean.
