In low densities, crown-of-thorns have little effect on coral reefs. Land based pollution has affected coral reefs greatly in past years. This is an example of interspecific competition because the branching coral and the ascidian are both competing for resources. They are second to great white sharks as man eaters and are known to be the deadliest species of shark in the ocean, but unlike great whites, they are not known to swim away after biting a human because their palates are so indiscriminate. As humans inhabit more and more of the coast, runoff from developing the land carries sediment, high levels of nutrients from agriculture, sewage outflows, and pollutants such as petroleum products and pesticides. Corals themselves have not avoided being on the menu despite substantial energy investments in structural and chemical defences to deter would be predators (Gochfeld 2004).

Coral reefs are the most eye-catching ecosystems in the ocean. Some of the diversity of coral reefs is associated with the invertebrate organisms To explore this idea, we created large reef pools, filled with water from either live or dead coral environments, and added a novel predator (a dottyback, Pseudochromis fuscus), along with 20 predator-naïve juvenile damselfish of two species, Pomacentrus chrysurus (responders) and P. moluccensis (non-responders). Globally, there are some 130 species of corallivorous fishes (fishes that consume live coral tissue) from 11 different families, although Butterflyfishes (family Chaetodontidae) account for approximately half of all of these (… They are a sluggish species, and in a year they move anywhere from 0.3-3km. Evidence of fish predation, from small blenny bites, to the trademark white scraps left behind on the coral’s surface from grazing parrotfish, are also commonly observed in Pacific reefs. Coral reefs are home for many organisms such as sponges, fish including large nurse sharks and reef sharks to groupers, clown fish, eels, snappers, and parrotfish, jellyfish, anemones, crustaceans, and algae.So, how do coral reefs support such a huge weight on their shoulders?

Reaching up to a half meter in diameter, a crown-of-thorns sea star is the largest tropical sea star and its favorite prey is corals. are fierce predatory fish that patrol outer reef areas in large schools. One example of a parasitic relationship in coral reefs includes crustaceans from the Copepoda or Isopoda orders, which attach to fish in the reefs, sometimes causing harm but at other times simply holding on and feeding on food particles that float by them. Crown-of-thorns sea stars feed on coral tissue, leaving only the skeleton of this Acropora … Learn how to identify the most common Hawaiian coral species and how to safely remove monofilament from the reef. These sea stars are found throughout the Indo-Pacific region, from the Red Sea to the western coast of Panama. 2. We plan to go back in the next few weeks and do a more thorough in-water clean up!
