Silversides

Silversides swirl through mangroves like a river in the sea. The dense forest of roots offers welcome shelter for the finger-size fish, which form large schools to try to confuse predators. Mangroves enhance reefs by providing a nursery area for vulnerable creatures and by trapping sediment that can smother coral. They also store carbon that might otherwise contribute to global warming.

Mangroves contribute to the system by trapping reef-bound sediment, filtering out pollution, and serving as nursery for many reef fish and invertebrates. The arched roots of mangroves like these form gateways through which multitudes of juveniles swim toward adulthood on the reef.
