Ecology of Amblyrhynchus cristatus
 
Main Ref. Gill, K., 1999
Remarks Ectothermic (Ref. 2648). Prefers temperatures between 35° to 37°C (Ref. 2659). Lives in colonies where shallow reefs occur with extensive intertidal zone and rocky coastline with 2 to 5 m above sea level. Lays eggs in softer substrates (Ref. 2623). Sleeps on the coastline or up on mangrove trees. Exhibits subtidal and intertidal feeding (Ref. 2650). Naturally dives at depths 1.5 to 5 m for 5 to 10 minutes (Ref. 2656) but can descend to 12 m for about 30 minutes (Ref. 2658).
