Water spiders move as easily through the water as they do across the cavern walls. Though they do not spin webs, they do encase their catch in a fine silk sack to smother and preserve their prey beneath the water. They tend to ignore creatures they are unfamiliar with, hunting only tiny crabs, fish, and similar Underdark fauna.

Spider Legs
The water spider can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check. The water spider can also walk on smooth liquid surfaces, like water or oil pools.
Bite
Melee Weapon Attack: +5 to hit, reach 5 ft., one
creature. Hit: 7 (1d8 + 3) piercing damage, and the
target must make a DC 11 Constitution saving throw,
taking 9 (2d8) poison damage on a failed save, or half
as much damage on a successful one. 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.
