Distribution

G. cristatipes is found off the Pacific coasts of South America, especially Chile and Peru, and extending as far northwards as Southern California,[3] and as far south as 33° 35' S.[4] The most closely related genera to Glyptolithodes all live in the Northern Hemisphere, suggesting that Glyptolithodes has migrated from its ancestral home to the Southern Hemisphere, where it is now most abundant.[3]

Dimorphism

This species shows notable sexual dimorphism, with the males have a right cheliped which is larger than the left.[4]
