You can survive out of water far longer than your aquatic kin.
Prerequisite(s): Aquatic subtype.
Benefit(s): You can survive out of water for a number of hours equal to your Constitution score before you risk suffocation. If you already have the ability to survive out of water for a limited amount of time before suffocating or suffering other ill effects, that amount of time is doubled. If you do not possess a land speed, you gain a land speed of 5 feet. If you possess a land speed that is less than 20 feet, your speed on land increases by 5 feet.
