Moon Coral (Fungia spp.) are solitary, free-living corals with disc-shaped bodies, often moving slightly across the reef floor.
39. How are corals classified?
Corals are classified by skeletal type (stony or soft), polyp size (SPS or LPS), and growth form (branching, plating, massive).
40. What is the importance of coral diversity?
Coral diversity supports marine biodiversity, ecosystem resilience, and aesthetic value, crucial for both natural reefs and aquariums.
41. What is bubble coral care?
Bubble Coral needs moderate light and flow, stable water conditions, and occasional supplemental feeding for optimal growth.
42. What is a blue coral?
Blue Coral (Heliopora coerulea) is a hard coral with a unique blue skeleton, slow-growing, and contributes significantly to reef structure.
43. How do corals reproduce asexually?
Asexual reproduction occurs through fragmentation or budding, allowing colonies to expand without sexual reproduction.
44. What is honeycomb coral?
Honeycomb Coral (Goniastrea spp.) is stony, forming large colonies with polygonal corallites resembling a honeycomb pattern.
45. What is a soft finger coral?
Soft Finger Coral (Sinularia spp.) is flexible, branching, and sways in currents, providing shelter and habitat for marine organisms.
46. How do corals compete for space?
Corals compete by rapid growth, extending sweeper tentacles, and producing chemicals to inhibit neighboring species.
47. Can corals recover from storm damage?
Many corals can regenerate from fragments after storms, though recovery depends on species, severity, and environmental conditions.
48. What is torch coral feeding?
Torch Coral benefits from planktonic foods, micro pellets, and occasional target feeding in aquariums for healthy polyp extension.
49. Are corals endangered?
Several coral species are threatened due to climate change, habitat loss, and overcollection. Conservation and marine protected areas are critical.
50. Why should we protect coral reefs?
Protecting reefs preserves biodiversity, coastal protection, fisheries, tourism, and the health of ocean ecosystems globally.
