The sperm whale's eye does not differ greatly from those of other toothed whales except in size. It is the largest among the toothed whales, weighing about 170 g. It is overall ellipsoid in shape, compressed along the visual axis, measuring about 7×7×3 cm. The cornea is elliptical and the lens is spherical.
Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

Many whales are known to breach the waters surface. The act of leaping generates more power than any other act performed by a non-human animal. Some whales, such as Sperm Whales , perform a breach by travelling vertically upwards from depth, and heading straight out of the water.
