Distribution and habitat preferences

Reef fronts, shallow reef flats.

Can be found in most habitats around Lizard Island.

Behaviour

G. retiformis is a hermaphroditic broadcast spawner. The larvae preferentially settle in shallow waters and this is the primary habitat zone for this species. Several studies have investigated the reproductive biology of G. retiformis.

This species is slow growing like most massive Favid corals, with growth rates typically less than 0.5cm/year. It is well adapted to shallow turbid waters however, and is able to switch between autotrophic and heterotrophic modes of feeding as environmental conditions change.
