Isopora cylindrica

(Veron and Fenner, 2000)


Studer, 1878

Characters: Colonies have thick sturdy branches which are circular in cross section and form clumps that may be several metres across. Branches slightly taper and have a single dome-shaped axial corallite. Radial corallites are small and immersed. The coenosteum is smooth.

Colour: Dark brown with white branch ends.

Similar Species: Isopora togianensis, which is almost indistinguishable underwater but which has less compact branches and has coenosteum tuberculae. See also I. brueggemanni.

Habitat: Shallow water, especially exposed upper reef slopes and flats.

Abundance: Common in Papua New Guinea, uncommon elsewhere.

Taxonomic Note: Placed in probable synonymy with Isopora togianensis by Wallace, Done and Muir (2012). However, these species have been clearly differentiated in both field and skeletal studies.

Taxonomic References: Veron (2000a) as Acropora cylindrica;
