Among the given options, sea turtles are known to have adaptations that enable them to stay underwater for extended periods. Sea turtles have specialized lungs that allow them to extract oxygen from the water and can hold their breath for long periods. Therefore, sea turtles are the most likely animal that fits the given description.

They do not require a moist environment to respire, but they do need a moist skin surface for gas exchange to occur effectively.
