Corals are the ultimate hybrids; each individual consists of a symbiotic pairing between plant and animal. They can photosynthesize during the day (as the purple and gold one doing) and then filter feed on nutrients during the night. Corals that depend more heavily on the latter tend to live in areas with moderate to strong currents - photo taken in the South Andaman Sea
