Night Drifters

Recent studies have shown larval fishes to be strong swimmers with sophisticated instincts for remaining in local waters. But exactly where they go between spawning and settlement remains a mystery.

Symbiosis on the Sand

Interactions between different species, whether above or below water, typically revolve around confrontations between predators and prey. At the opposite and more harmonious end of the spectrum, a scattering of unrelated species coevolved to form lifelong alliances for their mutual security. These relatively rare go-along-to-get-along partnerships provide a net benefit for both parties, improving each species’ reproductive success. The close living arrangement between weak-eyed alpheid snapping shrimp and sharp-eyed partner gobies is a classic example of symbiosis in the sea.
