Discover the 5 Animals That Eat Coral

The animals that eat coral can be broadly categorized into two groups: those that directly consume the coral polyps and those that graze on the algae that live on the coral surfaces.

While some species have specialized adaptations to feed on coral, others exhibit a more opportunistic approach.

In this exploration, we’ll delve into the fascinating world of animals that eat coral, examining their unique adaptations, ecological roles, and the potential impacts of their feeding behaviours on coral reef ecosystems.


What are the 5 Animals that Eat Coral?

1. Butterfly Fish:

The butterfly fish can occasionally resemble a butterfly’s wings. Its large, spherical, flat body is adorned with noticeable fins that surround its pelvis and back.

Occasionally, the dorsal fin on the back has sharp spines to protect it from predators. As was previously indicated, the short rows of bristle-like teeth in the mouth are the source of the family’s name.

Some are adapted to grip prey in tight spaces with long snouts and jaws that can reach up to 25% of their body length.

The most prevalent colours are orange, yellow, blue, and white, with huge spots on the back and dark, contrasting bands. These spots might help to confuse potential predators.

Butterfly fish typically don’t grow much longer than 8 inches, although the largest species can reach a foot in length.

What Does the Butterfly Fish Eat?

The butterfly fish, which feeds at the sea’s bottom, has developed a wide variety of jaw forms and sizes to allow it to squeeze through small openings in search of food.

Worms and other tiny invertebrates are among its preferred eats. Certain species also consume plankton, algae, and coral polyps.


2. Parrotfish:

With fused teeth that form a beak-like plate around the mouth and a second set of teeth in the back of the throat to grind up food, this fish is distinguished by its long, tapering body that is described as “fusiform.”

In certain species, their robust, massive scales can withstand the thrust of a spear. The majority of species fall between one and four feet in length.

With a maximum length of 4 feet 3 inches, the green humphead is the largest species. The bluelip, at five inches long, is the smallest.


What Does the Parrotfish Eat?

The parrotfish pulls algae from rocks and corals with its beak-like teeth.

The parrotfish are drawn to small polyps developing on the surface of the coral because they contain symbiotic algae that feed on the bits of coral that the fish excrete, helping to build sediments in their native environment.

Plankton, tiny organic materials, and a variety of smaller invertebrates are also consumed by parrotfish. In the Caribbean, sponges are the food source for both princess and queen parrotfish.

3. Coral-Eating Snail:

Certain species of sea snails, such as those in the marine gastropod mollusc family Murciadae, are corallivorous. Species that consume coral are particularly common in the genera Coalliophila and Drupella.

By removing tissue from the coral backbone and leaving behind white feeding scars, these snails eat on living coral. Overgrowth of algae on the scars may result from an overabundance of coral-eating snails.


4. Nudibranch:

Animals That Eat Coral

Within the order Nudibranchia, nudibranchs are any of the at least 3,000 species of marine molluscs without shells. Many of them live in the Indian and Pacific Oceans‘ coral reef environments. Depending on their genus or species, these animals frequently follow certain diets.

The most frequent nudibranch predators of live coral are those in the genus Phestilla, which mainly feeds on the soft tissues of hard corals.

Phestilla species are often prey-specific. For instance, Phestilla subodiosa is a species that feeds on anacropora and montipora coral.

The sole food source for Phestilla sibogae is Porites coral. The main food source for Phestilla goniophaga is stony coral in the Gonipora genre.


5. Triggerfish:

Animals That Eat Coral

The Balistidae family of triggerfish comprises about 40 species. The majority of species live and feed in coral reef settings, and they are found in tropical and subtropical oceans worldwide.

Triggerfish are very omnivorous animals that live on reefs. They eat fish, urchins, molluscs, worms, and small crustaceans.

To eat algae and microscopic invertebrates that live on branching corals, larger species—like the titan triggerfish (Balistoides viridescens)—often bite off parts of these corals.
