Heliofungia actiniformis is a solitary species of mushroom coral, a large polyp stony coral in the family Fungiidae. This coral is found in shallow water in the Indo-Pacific region. It is a zooxanthellate species. It is a popular coral in the reef aquarium trade; wild populations are threatened by disease, climate change, [3] and over-collecting, and the species is considered vulnerable by the IUCN.

Description

Although fixed to the substrate as a juvenile, this coral becomes detached later and is free-living as an adult. [4] It is circular or oval with a diameter of up to 20 centimetres (8 in) and height of 7 centimetres (3 in). The corallum (stony skeleton) is thick and solid. The septa (stony ridges) are in several orders. The early order septa are larger than later order ones and have more prominent, lobe-like or triangular teeth. All the septa are granulate, and continue to the underside of the corallum as fine ridges known as costae. There is an attachment scar in the centre of the underside. The polyp is thick and fleshy and has a single mouth surrounded by thick tentacles with knobs on the end. The tentacles are nearly always extended and superficially resembles a large sea anemone. [4]

Distribution

Heliofungia actiniformis is native to the eastern Indian Ocean and the central Indo-Pacific region, the northwestern, northern and eastern coasts of Australia, Japan, the China Sea and the island groups of the West Pacific. Its depth range is between about 1 and 25 metres (3 and 82 ft). It usually occurs on reef slopes or on reef flats. [1]

Ecology

H. actiniformis is a zooxanthellate coral, containing tiny photosynthetic, symbiotic organisms in its tissues. During the day these supply the coral with much of its metabolic needs. [2] The coral also feeds on zooplankton which are caught by the tentacles. Besides reproducing sexually by liberating eggs and sperm into the water column, this coral sometimes buds off a new polyp. [1] Polyps of H. actiniformis provide a micro-habitat to a wide range of associated fauna from cleaner shrimps to juvenile fishes. [5] [6]

Aquaculture

Many corals can be increased in number by detaching pieces of a colony and attaching them to the substrate. That is not possible with large polyp stony corals such as Heliofungia actiniformis, but it is hoped to remedy this by placing collecting devices above them when spawning is about to occur, mixing the eggs and sperm under controlled conditions and nurturing the larvae in tanks. The technique has been successfully applied to Acropora formosa . It is hoped that the resulting offspring will be able to be used to repopulate damaged reefs or to relieve the pressure of collecting corals from the wild for the reef aquarium trade. [7]

Status

Although this coral is common in some localities, it is vulnerable to the degradation processes which are occurring on coral reefs. It is susceptible to coral diseases and to coral bleaching and is likely to be threatened by climate change. It is heavily collected for the aquarium trade, being one of the top 10 exported corals from Indonesia, the largest exporter of the species. [8] In 2005, about 50,000 individuals were collected and exported from Indonesia. For these reasons, the International Union for Conservation of Nature has assessed its conservation status as "vulnerable". [1]

<span class="mw-page-title-main">Scleractinia</span> Order of Hexacorallia which produce a massive stony skeleton

Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as 25 cm (10 in) across but in colonial species the polyps are usually only a few millimetres in diameter. These polyps reproduce asexually by budding, but remain attached to each other, forming a multi-polyp colony of clones with a common skeleton, which may be up to several metres in diameter or height according to species.

Mussidae is a family of stony coral in the order Scleractinia. Following a taxonomic revision in 2012, the family is now restricted to species found in the Atlantic Ocean, with Pacific species transferred to the new family Lobophylliidae. Many species are referred to as brain coral because their generally spheroid form and grooved surface resembles the convolutions of a brain.

<span class="mw-page-title-main">Fungiidae</span> Family of corals

The Fungiidae are a family of Cnidaria, commonly known as mushroom corals or plate corals. The family contains thirteen extant genera. They range from solitary corals to colonial species. Some genera such as Cycloseris and Fungia are solitary organisms, Polyphyllia consists of a single organism with multiple mouths, and Ctenactis and Herpolitha might be considered as solitary organisms with multiple mouths or a colony of individuals, each with its separate mouth.
