Pocillopora fungiformis
Endangered encrusting coral endemic to Madagascar.
Pocillopora fungiformis is a species of colonial stony coral in the family Pocilloporidae. It is native to Madagascar and is notable for its mostly encrusting growth form, with patches reaching up to 2 m (7 ft) across. The species is endemic to Madagascar and is considered endangered due to its small range, uncommon occurrence, and susceptibility to bleaching and coral diseases.

Facts from the source article.
Lore & Background
Pocillopora fungiformis forms mostly encrusting colonies that can reach 2 m (7 ft) across. Larger colonies also develop bifurcating upright or sloping branches with flattened ends, growing up to 20 cm (8 in) in length. Irregular verrucae (lumpy skeletal outgrowths) cover the coral surface; on branches growing at oblique angles, these verrucae are more abundant on the upper side. The individual corallites are small and crowded, each with one septum more developed than the rest. The coral is some shade of greenish-brown.
The species is endemic to Madagascar, found on the north end and the south end of the island. It inhabits shallow reef habitats with strong water movement, to a maximum depth of 15 m (49 ft).
P. fungiformis has a small range and is an uncommon species. It is particularly susceptible to bleaching and coral diseases, and the reefs where it lives are under threat. The International Union for Conservation of Nature has assessed its conservation status as being 'endangered'.
Reader's Guide
Pocillopora fungiformis is significant as an endemic coral species restricted to Madagascar, where it occupies shallow, high-energy reef habitats. Its encrusting growth form, with occasional branching, distinguishes it within the genus. The species is notable for its vulnerability: it is particularly susceptible to bleaching and coral diseases, and its limited range and uncommon occurrence heighten its risk. The IUCN has assessed it as endangered, reflecting the threats to the reefs it inhabits. Its conservation status underscores the broader challenges facing coral ecosystems in Madagascar, where localized endemism and environmental pressures converge. The species' small distribution and sensitivity to stressors make it a marker for reef health in the region.
Did You Know?
- Pocillopora fungiformis is endemic to Madagascar, found only on the north and south ends of the island.
- Larger colonies of this coral develop bifurcating branches with flattened ends up to 20 cm (8 in) long.
Frequently Asked Questions
Who is Pocillopora fungiformis?
Pocillopora fungiformis is a colonial stony coral belonging to the family Pocilloporidae, found exclusively in the waters around Madagascar. It is one of the more unusual members of the birdsnest coral group because it grows primarily as a low, spreading encrusting patch rather than forming tall upright branches.
What are Pocillopora fungiformis's powers and role in the reef?
This species forms broad, flat colonies that can stretch up to 2 metres (about 7 feet) across, with individual branches reaching roughly 20 cm (8 in) in length. It typically lives on shallow reef slopes down to about 15 m (49 ft), where its encrusting habit helps it cling to rock surfaces and contribute to the structural complexity of Madagascan coral communities.
Why is Pocillopora fungiformis important to coral fans and conservationists?
Because it is endemic to Madagascar, every individual colony represents a genetic lineage found nowhere else on Earth. Losing this species would mean the permanent disappearance of a unique evolutionary line within the Pocilloporidae, making it a priority for in-situ protection and captive-propagation research.
Where can you find Pocillopora fungiformis in the wild?
It is restricted to coastal waters around Madagascar and does not occur naturally in any other region. Divers typically encounter it on the upper reef slopes at depths of up to 15 m (49 ft), where it appears as a sprawling, mushroom-like encrusting patch on hard substrate.
