What are coral reefs in Guadeloupe?
Coral reefs are formed by the accumulation of hard corals, which provide a habitat for a multitude of marine species. In Guadeloupe, these reefs are home to tropical fish, crustaceans, mollusks, as well as sea turtles and rays.
The history of Guadeloupe's coral reefs reflects their importance to the local community, especially for traditional fishing. However, they are now threatened by climate change, pollution, and coastal development. The Grand Cul-de-Sac Marin has become a living laboratory for scientists studying environmental changes and working on conservation solutions.
A famous anecdote involves the discovery of rare species, such as pygmy seahorses and endemic angelfish, attracting researchers from around the world.
