A jellyfish swarm is aquatic, and is never found on land.
Combat
A jellyfish swarm inadvertantly attacks any creature it encounters. The swarm deals 1d6 points of damage to any creature whose space it occupies at the end of its move. Any creature whose space it occupies at the end of its move must also make a Fortitude save. See poison below
Distraction (Ex)
Any living creature that begins its turn with a swarm in its space must succeed on a DC 20 Fortitude save or be nauseated for 1 round. The save DC is Constitution-based.
Wounding (Ex)
Any living creature damaged by a jellyfish swarm continues to bleed, losing 1 hit point per round thereafter. Multiple wounds do not result in cumulative bleeding loss. The bleeding can be stopped by a DC 10 Heal check or the application of a cure spell or some other healing magic.
Poison (Ex)
A jellyfish swarm has anesthetizing tendrils. A creature in its space must succeed on a DC 20 Fortitude save or be paralyzed for 3d6 rounds, and suffers 2d6 Con damage. On a successful save, the damage is only 1d6 Con damage. Secondary damage is 2d6 Con damage on a failed save, 1d6 Con damage on a made save. The save DC is Constitution-based.
A paralyzed character is frozen in place and unable to move or act. A paralyzed character has effective Dexterity and Strength scores of 0 and is helpless, but can take purely mental actions. A paralyzed swimmer can’t swim and may drown. A creature can move through a space occupied by a paralyzed creature—ally or not. Each square occupied by a paralyzed creature, however, counts as 2 squares.
Skills: A jellyfish swarm has no skills.
