Porpoises measure 4–6 feet long and weigh 110 to 170 pounds. The following stats may also be used to describe whales of similar size.

Species Traits

Porpoises have the following traits:

Aquatic: Porpoises can move in water without making Swim checks and cannot drown in water.

Blindsight (Ex): Porpoises can “see” by emitting high-frequency sounds, inaudible to most other creatures. This form of echolocation allows them to locate objects and creatures within 120 feet. A silence spell negates this and forces the porpoise to rely on its vision, which is approximately as good as a human’s.

Skill Bonuses: Porpoises gain a +4 species bonus on Listen and Spot checks. These bonuses are lost if blindsight is negated.

Bonus Feat: Porpoises gain the bonus feat Weapon Finesse (slam).
