The Great Barrier Reef is threatened not only by climate warming and ocean pollution, but also by thorns crown sea stars (Acanthaster planci). Biologists have proposed another solution to this problem: to distract Acanthaster with their own pheromones.

Coral Reef will be Protected from Gluttonous Sea Stars

Researchers found that these sea stars communicate, highlighting certain chemicals. Based on these substances, bait was created, which was placed in the area of the coral reef. Attracted by the pheromones, the stars form clusters, resembling balls, and then they will be easy to move away from vulnerable reef. Previously they have already tried to fight with thorny crowns with the help of underwater robots. During the year one individual is destroying 13 square kilometers of corals.
