Cave-diving venues can be found on all continents except Antarctica, where the average temperature is too low for water to remain liquid in caves.

Keeping well hydrated, fed and warm would help with physical and mental acuity and hopefully decrease the number of these errors.. A distinction is made by recreational diver training agencies between cave-diving and cavern-diving, where cavern diving is deemed to be diving in those parts of a cave where the exit to open water can be seen by natural light. Unfortunately, on his 18th day in the cave, Collins passed away from starvation, hypothermia, and thirst.
