You can speak, read, and write Common, Sylvan, and Axolotl. 

Your Constitution score increases by 1 and one more ability score of your choosing will increase by 1.

Axolittles reach adulthood at around 15 years old. They live somewhat shorter than humans, living up to 70 years.

Community-oriented and eco-conscious, Axolittles tend toward a neutral good alignment.

Axolittles are called "little" but are quite large compared to their axolotl cousins. In comparison to humans, however, they are indeed little! They stand anywhere from 2-3 feet tall. Your size is Small.

Axolittles have small legs that are better suited for swimming. Your base walking speed is 20 feet, but your base SWIM speed is 35!

You can breathe air and water.

Axolittles can regrow almost any part of their body, including their limbs, organs, and brain. Some have even regenerated body parts multiple times without scarring. 

When you take a long rest, you can focus on one minor wound and completely close it or close a major wound throughout multiple long rests.

If a part of your body is lost, the DM will tell you how long until it is completely grown back.

Axolittles prefer the dark and have poor eyesight, so they can see in the dark better than in bright light.

Accustomed to life underwater, you have superior vision in dark and dim conditions. You can see in dim light within 120 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray. 

You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight.
