Brain coral - Platygyra daedalea

Image of Merulinidae Verrill 1865

Description:

Brain corals are slow-growing and develop into a range of shapes. This one was almost perfectly round. Symmetry in nature. Brain corals extend their tentacles at night to feed, and some have long defensive tentacles that they use to sting and repel other corals that grow too close
