The eared seals — fur seals and sealions — are marine. As the name implies, otariids have small ear pinnae. The hind limbs are employed in terrestrial locomotion and nails are conspicuous on the middle three pedal digits. Sexual dimorphism in size exists, the males being larger. The tail is present, but short and in mature males the scrotum is external and obvious. The anterior limbs are larger and the neck longer than in phocids. This family includes the only marine mammal endemic to Australia.

Otariids occur in both hemispheres, but are not found in the colder polar and warmer tropical waters. Fish, crustaceans and cephalopods are included in the diet. Gregarious, assembling in large herds during the breeding season, this family includes most of the seals harvested for the fur industry.
