Why are Staghorns are so vulnerable? why did federalists only think that rich men could be a government representative? If the ocean temperature stays high for a prolonged period of time, this leads to the death of the coral. NOAA Fisheries coordinates spawning observations and larval culture with a network of researchers working throughout the Caribbean, including academic researchers and professional aquarists from public zoos and aquaria. Other threats to staghorn coral are ocean acidification (decrease in water pH caused by increased carbon dioxide in the atmosphere) that makes it harder for them to build their skeleton, unsustainable fishing practices that deplete the herbivores (animals that feed on plants) that keep the reef clean, and land-based sources of pollution that impacts the clear, low nutrient waters in which they thrive. In exchange, the algae get a place to live and protection from predators. Staghorn corals are also nocturnal predators, waiting until the sun goes down before they unfurl their tentacles and start hunting. Secondly, the skeleton, or corallite, of a new polyp, is built by specialised 'axial' corallites. Why are staghorn corals so vulnerable compared to other corals?
