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 .
