Yellow longnose butterflyfish browsing on coral polyps. A corallivore is an animal that feeds on coral. Corallivores are an important group of reef organism because they can influence coral abundance, distribution, and community structure. Corallivores feed on coral using a variety of unique adaptations and strategies.

[1] Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and ...
Corals are vital for the marine creatures that rely on them for food and shelter, but also for humans. They are an indirect food source for an estimated 1 billion people, by helping support ...
Trees, by definition, cannot have cycles and – contrary to networks – are thus inappropriate to reflect horizontal events, such as hybridization or endosymbiosis, while fan corals allow links between branches; Trees are computationally feasible, and remain fundamental tools in revealing phylogenetic relationships; corals can be constructed ...
Paragorgia arborea is a species of coral in the family Paragorgiidae, commonly known as the bubblegum coral because of its bulbous branch tips. It mainly grows in depths between 200 and 1,300 metres (700 and 4,300 ft) at temperatures between 3 and 8 °C (37 and 46 °F).
