race features:
Natural Swimmer. Your base walking speed is 30 feet. You gain a natural swim speed of 30 feet and may hold your breath for a number of minutes equal to twice your constitution modifier
Pounce. If you move at least 20 feet straight toward, or jump at least 5 feet down onto a creature and then hit it with a melee attack on the same turn, if that creature is one size larger than you or smaller, the target must succeed on a Strength saving throw (save DC of 8 + your proficiency modifier + your choice of either Strength or Dexterity modifier) or be knocked prone. If the target is knocked prone, you can make one claw attack against it as a bonus action.
The Hunter’s Awareness. After countless hunts, you have learned how to become acutely aware of your surroundings. As a reaction, you may pause to heighten your perceptions, for the next 10 minutes you gain advantage on all Perception, Insight and Survival skill checks. Once you use this trait, you can’t use it again until you finish a short or long rest
