The Orange cup coral is a species of solitary cup coral, a stony coral in the family Dendrophylliidae. Its main prey is zooplankton caught by the tentacles. This coral can also extract dissolved organic carbon from sea water, and during the winter months, when there is a scarcity of zooplankton, this source of nutrition may be critical for the coral's survival.

Spotted in tide pools at Tongue Point. It is native to the eastern Pacific Ocean. It occurs on rocky coasts from the low intertidal zone down to about 290 m (950 ft). It appreciates habitats with vigorous water movement, such as surge channels, and often grows in caves and under overhangs.
I was fortunate to find this coral - over the seemingly hundreds of tide pools I studied it only existed in 2 pools that I found.
