👉 The whale weapon, also known as the spermaceti organ, is a large, complex structure found in the heads of sperm whales. This organ contains a high concentration of oil, which is used by the whale for buoyancy control and as a potential weapon. When threatened or during hunting, whales can forcefully expel this oil from the organ in a spray, creating a loud, shockwave-like sound and a dense cloud of oil that can disorient or injure predators or competitors. This unique adaptation serves both defensive and predatory purposes, showcasing the remarkable evolutionary adaptations of these marine mammals.
