About the Marine Iguana

The marine iguana (Amblyrhynchus cristatus) is endemic to the Galápagos Islands and is the only extant lizard adapted to a fully marine lifestyle. It feeds almost exclusively on marine algae, diving into cold ocean waters and using its strong limbs and laterally flattened tail to swim efficiently. The skull of the marine iguana reflects these unique adaptations, with flat, tricuspid teeth for grazing algae, and a strong jaw to grip slippery surfaces underwater. Males can grow over 4 feet (1.2 meters) in length, and their heavily ossified skulls are also used in territorial headbutting during mating season.

This species is considered Vulnerable on the IUCN Red List, facing threats from climate change, pollution, invasive species, and human disturbance.

Skull Production

This replica was made using a high-resolution 3D scan of a real Amblyrhynchus cristatus skull. It is cast in durable resin and carefully hand-finished to highlight the cranial ridges, flattened teeth, and compact jawline. This model offers exceptional anatomical accuracy and is ideal for both study and display.

Perfect For:

• Reptile and island species collectors
• Educators & museums exploring Galápagos biodiversity or evolutionary adaptation
• Herpetologists & evolutionary biologists studying iguanid morphology
• Artists & sculptors seeking a rare and unique reptilian reference

This marine iguana skull replica captures the essence of one of evolution’s most fascinating and ecologically unique reptiles, making it a standout addition to any natural history, educational, or conservation-focused collection.
