Montipora digitata ( German )

provided by wikipedia DE

Montipora digitata (lat. digitatus = fingerartig) ist eine Steinkoralle (Scleractinia) aus dem tropischen Indopazifik. Im Gegensatz zu den anderen Arten der Gattung Montipora, die eher krustig wachsen oder blattförmige, nahe am Substrat wachsende Strukturen bilden, wächst Montipora digitata buschförmig und bildet dünne, poröse, stumpf endende Äste, die leicht abbrechen. Sie ist meist grün, kann aber auch von oranger, violetter oder blauer Farbe sein. Die Wachtumsspitzen an den Enden der Äste sind weiß.

Besonders letztere Farbformen sind bei Meerwasseraquarianern sehr begehrt. Montipora digitata gehört zu den einfacher zu haltenden Steinkorallen und kann leicht durch Fragmentation künstlich vermehrt werden.

Montipora digitata

provided by wikipedia EN

Montipora digitata, also known as finger coral, is a species of stony coral. It is found in shallow water in East Africa, the Indo-West Pacific, Kenya, Mozambique and Rodriguez.

Description

Colonies of Montipora digitata are digitate or bushy with vertically aligned, anastomosing branches, and forming hemispherical mounds that may be 40 centimetres (16 in) or more in diameter. The corallites are small and deeply sunk into the skeleton, giving it a pitted appearance. This coral is usually pale cream, pale yellow or brown.[2]

Biology

Montipora digitata is a zooxanthellate species of coral.[2] It obtains most of its nutritional needs from the symbiotic dinoflagellates that live inside its soft tissues. These photosynthetic organisms provide the coral with organic carbon and nitrogen, sometimes providing up to 90% of their host's energy needs for metabolism and growth. Its remaining needs are met by the planktonic organisms caught by the tentacles of the polyps.[3]

Montipora digitata is a simultaneous hermaphrodite. Spawning takes place once a year and is synchronised among the colonies in any one locality. Packets of eggs and sperm are released into the water column and, being buoyant, rise to the surface. Here the packets break up and cross-fertilisation takes place with gametes from different colonies intermixing.[4]

Status

This coral is a common species and is relatively unaffected by coral bleaching. The main threats faced by corals are related to climate change; the mechanical destruction of their coral reef habitats, increasing damage from extreme weather events, rising sea water temperatures and ocean acidification. The International Union for Conservation of Nature has assessed the conservation status of this species as being of "least concern". All corals receive protection by being listed on CITES Appendix II.[1]

Description

provided by World Register of Marine Species
Colonies are digitate or arborescent with anastomosing upright branches. Corallites are immersed and are small (especially colonies from very shallow water). Colour: pale cream or brown. Abundance: common. May be a dominant species on shallow mudflats (Veron, 1986). Digitate colonies with anastomosing branches, forming subspherical mounds over 40 cm across. Corallites slightly sunken, giving the surface a pitted appearance. Colour: uniformly light brown to pale yellow. Habitat: diverse, including shallow lagoons (Richmond, 1997).
