Millepora dichotoma, the net fire coral, is a species of hydrozoan, consisting of a colony of polyps with a calcareous skeleton. Part of the metabolism of the fire coral relies on zooxanthellae included in their anatomy. They are found from the Red Sea to Samoa and South Africa.^[1] They form fan-shaped colonies up to 60 cm across, but clumps may be several metres across. Coloured mustard to olive-yellow, the fans form in a single plane.

Feeding polyps snare plankton from the passing current along exposed portions of upper reef slopes up to 15 m depth, growing transverse to the prevailing current to ensure maximum exposure to passing foodstuff. The stinging nematocysts contain a toxin which causes painful burn-like wounds on contact. At worst, this may cause collapse in those with a severe allergic reaction. Skin irritation may continue for up to two weeks.
