Caulibugula mortenseni (Marcus, 1925) (Fig. 3A‒C) Brownish-orange species forming clusters of long stalks up to 30 cm long, each of which ends in an array of radiating branches (Marcus, 1925) that, underwater, give the appearance of a starburst (Fig. 3A). Branches are narrowly biserial and some zooids bear an elongate birdshead avicularium at their proximal end (Fig. 3C). The type locality is Sunda Strait, Indonesia.
