Night Dives Reveal Hidden Alliances
Since 2016, Rich Collins has been plunging into the pitch-black waters off the coast of Palm Beach, Florida, at night, camera in hand, in pursuit of blackwater photography.
These nighttime dives have given him a unique window into the lives of sea creatures, including many that usually stay hidden in deeper waters, but come up to the surface after dark to feed.
Collins and his fellow divers have observed that some juvenile fish interact with larval tube anemones in interesting ways, with the fish either sticking close to the anemones or even carrying them around.
These “symbiotic associations” are described in a recent paper published in the Journal of Fish Biology, for which Collins was a co-author.
