Does a rain forest have a greater variety of species than in a coral reef?

Rainforests and coral reefs both boast incredible biodiversity, but rainforests typically have a greater variety of species overall. Tropical rainforests are home to an estimated 50% of the world's plant and animal species, despite covering only about 6% of the Earth's land surface. Coral reefs, while also rich in biodiversity and often referred to as the "rainforests of the sea," support a more limited number of species relative to their size. However, both ecosystems are crucial for global biodiversity and face significant threats from environmental changes.
