The ovicells of this species appear globular when full of embryos. The embryos are yellow and present from July to September. The first zooid to form a colony after metamorphosis from a free-swimming larvae (known as the ancestrula) is vase-shaped, having a circular, terminal frontal membrane with no surrounding spines (Ryland & Hayward, 1977).
