Appearance

Pocillopora colonies are covered with bumps called verrucae. On shallow reefs exposed to heavy waves, species of Pocillopora are relatively small, while in deeper water their branches are thin and open. Branches also usually have rounded tips.

Color varies between shades of green, brown and yellow, but pink is also common.

Each polyp has a ring of 12 small tentacles which usually extend at night.

Habitat

Coral reefs

Diet

Pocillopora coral receives most of its nutrients from its relationship with zooxanthellae, a type of algae that performs photosynthesis and lives within the coral.

Life History

Species of the Pocillopora genus have been observed to reproduce both sexually and asexually. Sexual reproduction is done by either releasing eggs and sperm into the water, or internally brooding larvae inside the coral polyp. Larvae called planulae then disperse, settle, and form a new polyp.

Several species of this coral genus are hermaphrodites, meaning that an individual has both male and female reproductive organs.

IUCN Status

Endangered

Ecosystem & Cultural Importance

Pocillopora are reef-building corals, acting as the foundation for reef ecosystems and providing habitat for numerous fish and invertebrate species.

Pocillopora species are among the most at risk reef-building corals to climate change.
Distributed throughout the Indo-Pacific region. Pocillopora corals are also found in the eastern Pacific Ocean.
This animal is not native to the Oregon Coast, however is found in the larger Pacific Ocean. It lives in the Aquarium as part of our Connected Coasts gallery.
Pocillopora is often the research “guineapig” of the coral world. Most of the early discoveries about the growth and reproduction of corals were made with Pocillopora damicornis.
