Orange cup coral

Description:

This coral is not building reefs. It is heterotrophic and does not contain zooxanthellae in its tissues as most corals do and it coral extends beautiful translucent tentacles at night to feed on zooplankton.

Habitat:

Orange-cup corals often dominate tropical habitats not occupied by other coral species, such as wrecks and cryptic reef habitats, but are also found in very cold water throughout the world.
