Lobed
brain coral
Lobophyllia sp.*
Family Lobophylliidae
updated
Oct 2016
Where
seen? This fleshy dome-shaped hard coral with large 'teeth' is commonly
seen on many of our Southern shores.
Features: Colonies seen about
15-20cm, sometimes much larger. Those seen on the intertidal were
hemispherical with rather flat tops. Some have corallites that are
branching and trumpet-shaped (phaceloid): long column flaring out
at the top to irregular oval shapes (2-5cm in diameter). The branching
corallites may be packed closely to one another, or spaced apart.
They are arranged with the broad, flared portions facing out so the
colony forms an overall spherical shape. Elsewhere, these colonies
are reported to reach 5m across or more, some with branches up to
30cm long. In others, the corallites form meandering valleys with
separate walls (flabello-meandroid).
Corallites walls are thick with large partitions (septa) that have
long, prominent 'teeth'. When submerged, the skeleton is covered with
thick, fleshy tissue which has bands of 'pimples' (not smooth). Polyp
tentacles are only extended at night and the tentacle tips are usually
white. It is said that Lobophyllia hemprichii has such long
tentacles (5cm) that when extended, the coral may be mistaken for
a sea anemone. Colours seen include green, blue, purplish.
Mistaken identity Lobophyllia
corymbosa may resemble some species of Trumpet
corals (Caulastraea sp.) as both have branching corallites
with circular openings. More on how to tell apart hard
corals with big rings and fleshy tissue. |
