Be sure to check out the corals next time you're at the cuttlefish exhibit in Spineless. While you won’t see this level of detail with the naked eye, this video captured with a macro lens shows a coral feeding up close. A coral’s diet consists primarily of microscopic zooplankton. During feeding, a coral polyp extends its tentacles away from its body and waves them in the water to capture zooplankton, bacterioplankton, and other food particles. | New York Aquarium
