Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 4 (2d8 + 7) piercing damage, and the target must succeed on a DC 11 Constitution saving throw or take 10 (3d6) poison damage. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.
Claw. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (4d6 + 7) bludgeoning damage, and the target is grappled (escape DC 11). The crab has two claws, each of which can grapple only one target.
