Photo of Animalia: species: Physogyra lichtensteini (Lizard Island Field Guide)

Physogyra lichtensteini at the northern tip of Yonge Reef near Lizard Island. Grace Frank notes that this colony has its vesicles partly retracted, showing some of the skeletal characteristics of Physogyra - short, widely spaced meandroid valleys and the hemispherical disc shapes made by the septa.
