Also known as sperm whales, these creatures can be up to 60 feet long. They prey on giant squid.

Blindsight (Ex): Whales can "see" by emitting high-frequency sounds, inaudible to most other creatures, that allow them to locate objects and creatures within 120 feet. A silence spell negates this and forces the whale to rely on its vision, which is approximately as good as a human's.

Skills: Whales gain a +4 racial bonus to Spot and Listen checks. These bonuses are lost if Blindsight is negated.
