Coral Polyps
Coral polyps are tiny, soft-bodied organisms that form the base structure of coral reefs. These invertebrates have a cylindrical body with a central mouth surrounded by tentacles used for feeding and defense. Coral polyps extract calcium carbonate from the ocean to build protective exoskeletons, which contribute to the formation of intricate reef systems. These organisms have a symbiotic relationship with photosynthetic algae called zooxanthellae, which provide them with nutrients through photosynthesis. Coral polyps come in a variety of shapes, sizes, and colors, and play a crucial role in marine ecosystems by providing habitat and food for a diverse range of marine species.
