Sea cucumbers may save coral reefs

Tropical sea cucumbers could protect coral reefs from further degradation due to climate change, according to researchers.

Scientists at One Tree Island, University of Sydney’s research station on the Great Barrier Reef, found that sea cucumbers help counter the negative impact of ocean acidification on coral growth.

Sea cucumbers produce calcium carbonate, a key component of coral, when digesting sand, and their natural digestive processes also increases the pH levels of the water.
