Corbulipora tubulifera Hincks, 1881

Corbulipora tubulifera occurs in southeastern Australia. Colonies show three different growth form 'phases'. The left illustration is of the encrusting phase, which is usually the first in the life cycle (astogeny) of the colony.

Each zooid has a costate shield, made up of about 14 hollow spines or costae. The gaps between the costae are lacunae (true pores), and the round pores leading into the interior of the costae are a type of window termed pelmatidia (or pelmata). The pair of distal costae form an apertural bar. Transition from flustrine phase to bilaminar phase.
