The human body form of a coral is recognized as a ‘polyp’. Polyps are tubular, with tentacles plus a mouth at a single end. The coral secretes a hard material referred to as calcium carbonate to be a protective exoskeleton. Coral reefs are fashioned through the exoskeletons of coral colonies. https://stephenawrle.sasugawiki.com/7228502/how_animal_porn_can_save_you_time_stress_and_money
