Quick answer
Corals feed by filtering plankton, supplemented by algae symbionts, adjusting with season, age, and what is abundant in Warm, shallow tropical seas worldwide. That label is a preferred pattern, not every item an individual might sample.
Key takeaway
Corals feed as filter feeders plus algae symbionts, adjusting with season, age, and what is abundant in Warm, shallow tropical seas worldwide. That label is a preferred pattern, not every item an individual might sample.
Coral diet overview
Corals (Anthozoa) are best summarised as Filter feeder plus algae symbionts. Anatomy and habitat (Warm, shallow tropical seas worldwide) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How corals find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Coral role in the food web
As consumers in their food web, corals move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild corals. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Range and habitat
Corals inhabit Warm, shallow tropical seas worldwide, with the greatest diversity in the Indo-Pacific. Their preferred habitat includes warm, shallow tropical seas worldwide, where they find food, shelter, and breeding sites. Population density varies with prey availability, water access, and human disturbance. Protected areas and intact corridors remain essential for long-term persistence across multiple regions.
Physical characteristics and behaviour
Adult corals typically measure about 0.3 m in length and weigh roughly 1 kg (2 lb). They can sprint at None; corals are fixed in place when hunting or escaping predators. Corals are known for the tiny reef-building animals of tropical seas — social structure, daily activity, and seasonal movements all reflect pressures in their native environment.

Coral FAQs
What do corals eat?
Corals feed as filter feeders plus algae symbionts, adjusting with season, age, and what is abundant in Warm, shallow tropical seas worldwide. That label is a preferred pattern, not every item an individual might sample.
What is the scientific name of the coral?
Anthozoa — used in research and conservation listings for corals.
Where do corals live?
They are associated with Warm, shallow tropical seas worldwide. Local presence depends on food, cover, and human land use.
What is the conservation status of corals?
Listed in our guides as Least Concern. Check the IUCN Red List and national assessments for the latest formal category.
