Additionally, 50% of butterflyfish species are corallivores, making corallivory their most common feeding method. [5] [6] Corallivorous fish come from 11 different families. [5] 39 species are obligate corallivores. [5] Butterflyfish have a wide range of adaptations that facilitate coral consumption.
Trophallaxis: eating food regurgitated by another animal; Zoopharmacognosy: self-medication by eating plants, soils, and insects to treat and prevent disease. An opportunistic feeder sustains itself from a number of different food sources, because the species is behaviourally sufficiently flexible.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Biomechanically this is a unique and extreme feeding method, for which the animal at first must accelerate to gain enough momentum to fold its elastic throat (buccal cavity) around the volume of water to be swallowed. [25] Subsequently, the water flows back through the baleen, keeping back the food particles.
They have adaptations to allow for this including stout flattened teeth, hypertrophied jaw adductor muscles and robust jaws to feed on hard prey such as crustaceans and molluscs. Sharks that crush prey have teeth with small, low rounded cusps that are numerous per row, or are molariform. The molariform teeth are smoothly rounded, lack cusps ...
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
