How do you think this level of fishing will affect the populations of the other fish in the simulated reef? What happens when sound pressures are large? How do marine invertebrates detect sounds? Description Parrotfish are named for their dentition, which is distinct from other fish, including other labrids.Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates (which contributes to the process of bioerosion). How is sound used to measure temperature in the ocean? Reproductive mode: Parrotfish are pelagic spawners, they release many small buoyant eggs, which become part of the plankton. Stoplight parrotfish: Yellowtail snapper: Queen angelfish: Nassau grouper: 2. There is unanimous agreement that the functional role of parrotfish as lower trophic level herbivores is a key component in the structural integrity and resiliency of shallow water coral reef ecosystems. Parrotfish biomass was the most negatively associated with total algal cover with 4.0 mt/km 2 as the threshold biomass level. Stoplight Parrotfish The stoplight (Sparisoma viride) grows to between 12-18 inches and is usually found in coral reefs throughout Bermuda, Florida, Caribbean Sea, Gulf of Mexico and as far south as Brazil.
