Editing Zalophus (section)

==Description==
The seals of the genus ''Zalophus''  present a striking [[sexual dimorphism]], since the adult males have a pronounced [[sagittal crest]], and weigh, in the Californian species, between 300 and 380&nbsp;kg with 240&nbsp;cm long, and the females 80 to 120&nbsp;kg with between 180 and 200&nbsp;cm. As with all ear seals, the males are significantly larger and heavier than the females. The males are dark brown in color, the females are lighter. In contrast to the other ear seals, the males do not have a clearly defined mane. In the Galapagos species the males weigh about 250&nbsp;kg with a length of 250 to 270&nbsp;cm, while the females weigh from 60 to 100&nbsp;kg with a length of between 150 and 170&nbsp;cm.

They have a streamlined body, with a layer of fat under the skin, to provide warmth and buoyancy. The coat is brown. They have large eyes that help compensate for low light levels in the underwater environment, while their whiskers increase their sense of touch. The nostrils close automatically once they touch the water. Their long front fins rotate outward for better movement on land, and propel them forward in the water, where they stay as long as possible.
