Physiology L. santolla lives in cold-temperature and subantarctic waters. Ideal temperatures for its Crustacean larva and juvenile development range from , and its larval stages are nonfeeding. It experiences respiratory acidosis and hyperglycemia after prolonged exposure to air; however, these levels eventually return to normal after reimmersion, making it capable of withstanding long periods of aerial exposure with no detrimental effect on mortality.

Fishing

The population of Lithodes santolla has seen a dramatic decline due to commercial fishing.

The lucrative centolla fishery around Tierra del Fuego led to an incident in August 1967 when the Argentine schooner Cruz del Sur was found fishing from Gable Island and had to be escorted out of Chilean waters by the Chilean patrol boat Marinero Fuentealba.

This event among many others led to the Beagle conflict in the late 1970s.

The United States Food and Drug Administration lists the centolla crab and southern king crab as two separate species: Lithodes antarcticus and Lithodes santolla respectively. Other sources consider Lithodes antarcticus to be a synonym of Lithodes santolla.
