Di cosa parla
- Reef corals are highly diverse and productive marine ecosystems that support a vast array of species despite occupying only a small portion of the ocean surface.
- Coral polyps, which form coral colonies, are colonial animals with transparent bodies and tentacles containing cnidocytes; they can be classified as hard or soft corals based on their calcium carbonate skeleton presence.
- Zooxanthellae, symbiotic algae that live within the coral tissues, provide essential nutrients through photosynthesis and offer protection to the polyps in return for a habitat and carbon dioxide, leading to coral bleaching when they leave due to stress factors like temperature changes or pollution.
