Capnella sp. Indo-Pacific. Polyps found on small branches at end of only a few branchings, and are not retractable. Have club-shaped sclerites within. Often misidentified as Litophytons.
Genus Capnella Gray 1869: (Kenya) Tree Coral. Have small arborescent headed colonies, with polyps that are non-retractile.



Genus Paralemnalia Kukenthal 1913: Shorter, more numerous branching (finger-like lobes arise from common bases) than Litophyton, Lemnalia spp. Polyps can or cannot withdraw completely, colonies are limited in their contraction. Red Sea 08.



Acropora squarrosa (Ehrenberg 1834).  /COTW
Characters: Colonies are usually upright bushes with short compact branches. Axial corallites are large and dome-shaped, with thick walls. Radial corallites have a wide range of sizes but are identical to axial corallites in shape and appearance. All corallites are smooth and rounded and have small openings. The coenosteum is smooth.Colour: Cream or pale brown. Corallite centres are a distinct blue or pink, depending on depth.
Similar Species: 
Acropora plantaginea, which has relatively crowded radial corallites. See also A. verweyi, which has neat pocket-like radial corallites and A. maryae, which has thinner branches, does not form compact clumps and has less exsert radial corallites. See also A. rosaria and A. granulosa.
Habitat: 
Upper reef slopes.
