race features:
Hasty Dodge: You can take a point of Exhaustion to succeed a Dexterity Saving Throw or give your attacker Disadvantage on a single attack. You can make the decision after either roll but before damage dice are rolled.
Slick Skin: Your wet slimy skin means you only have to submerge in water every 6 days. You also have Advantage on escaping being Grappled or Restrained.
Readied Movement: During a Surprise round of combat, you can always at least take your Move action.
"Piki are smaller then their relatives. Their dorsal fins are a lot smaller and closer to their bodies and their teeth are shorter as well. What they lack in size they make up for in speed however. Able to maneuver and wriggle out of trouble. They are also the more timid of the Sawgrim."
