Swimming speed: Lizardfolk have a swimming speed of 30 feet.

Bite: Lizardfolk's fanged maw is a natural weapon, which they can use to make unarmed strikes. If they hit with it, they deal piercing damage equal to 1d6 + Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

Powerful tail: As a bonus action, Caimari can make an unarmed tail strike. It deals 1d6 bludgeoning damage and forces the target to make a Strength saving throw (DC = 8 + proficiency bonus + Strength modifier) or be knocked prone. They can use this a number of times equal to their proficiency bonus per long rest.

Hold breath: Lizardfolk can hold their breath for up to 15 minutes at a time.

Natural armor: Lizardfolk have tough, scaly skin. When they aren't wearing armor, their AC is 13 + Dexterity modifier. They can use their natural armor to determine your AC if the armor they wear would leave them with a lower AC. A shield's benefits apply as normal while they use their natural armor.

Amphibious defense: When Caimari are in water or swamp terrain, they have advantage on Dexterity saving throws against effects they can see.

Aquatic camouflage: Caimari can attempt to hide even when only lightly obscured by mud, foliage, or murky water.
