Mangrove Tree Crab, Costa RicaThe mangrove tree crab lives high in the branches of mangrove trees along tropical coastlines. Unlike most crabs, it spends much of its life out of water, using its hooked legs to climb and cling to bark and leaves. It feeds primarily on mangrove leaves but also snacks on algae, insects, and detritus, making it both a herbivore and a scavenger. When threatened, it can drop from the canopy into the water below, quickly scurrying to safety. Small but ecologically important, this crab helps recycle nutrients and maintain the delicate balance of the mangrove ecosystem. I photographed this on in Piedras Blancas National Park in southern Costa Rica. Nikon Z8 with Nikkor 500mm PF lens, ISO 1000, f/5.6 at 1/125th of a second, Godox 860iii flash.
