Seagrass meadows. (A) Distribution of seagrass meadows. Like that of corals and mangroves, seagrass species richness is greatest in Southeast Asia and northern Australia. (B) A green sea turtle (Chelonia mydas) hovers over turtle grass (Thalassia testudinum) in Hol Chan Marine Reserve in Belize. A single acre of seagrass can support 40,000 fish and 50 million invertebrates such as clams, burrowing worms, sea stars, and conches.
