eared seal
C2 (Very Low Frequency)Technical / Scientific (Zoology, Marine Biology, Wildlife Documentation)
Definition
Meaning
A type of seal belonging to the family Otariidae, characterized by the presence of small external ear flaps, a flexible neck, and limbs adapted for walking on land, as opposed to 'true' or earless seals.
Any marine mammal in the family Otariidae, which includes sea lions and fur seals. They are distinguished from phocids (true seals) by their visible ear pinnae, ability to rotate their hind flippers forward for terrestrial locomotion, and generally more social and vocal behavior. The term is primarily used in zoological and wildlife contexts.
Linguistics
Semantic Notes
This is a hypernym (superordinate term) for sea lions and fur seals. It is a compound noun where 'eared' is descriptive of a key anatomical feature. The term is neutral and descriptive, not a common name used by the general public, who are more likely to use 'sea lion' or 'fur seal' specifically.

Examples
By CEFR Level
- The sea lion is a kind of eared seal.
- Eared seals can walk on land better than other seals.
- Marine biologists distinguish eared seals from true seals based on the presence of external ear flaps.
- The Galápagos fur seal, an eared seal, is adapted to warmer equatorial waters.
- Taxonomically, the family Otariidae encompasses all eared seals, which are further divided into the subfamilies of sea lions and fur seals.
- The locomotive advantage of eared seals on terrestrial haul-out sites is attributed to their rotatable hind flippers.
Learning
Memory Aids
Mnemonic
Imagine a seal with big, floppy DONKEY EARS. It's a silly image, but it links 'eared' directly to the key feature that distinguishes it from other seals.
Conceptual Metaphor
FAMILY MEMBERSHIP: 'Eared seal' conceptualizes the animal as a member of a specific biological family group with defining traits.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'eared' as 'ушастый' in a colloquial sense, as it might sound childish. The standard Russian biological term is 'ушастый тюлень'.
Common Mistakes
- Misusing it as a synonym for all seals. Confusing 'eared seal' with 'seal lion' as if they are mutually exclusive (sea lions are a subset of eared seals).

FAQ
Frequently Asked Questions
No, a walrus belongs to its own family, Odobenidae. While it shares some characteristics with eared seals (like the ability to walk on land), it is not classified as one.
"Eared seal" is the family name (Otariidae). "Sea lion" refers to animals in one of the two subfamilies within Otariidae. So, all sea lions are eared seals, but not all eared seals are sea lions (some are fur seals).
Not necessarily. Both have excellent hearing adapted for water. The 'eared' descriptor refers only to the visible external structure (pinna), not auditory capability.
Eared seals are found throughout the world's oceans, primarily in cold to temperate waters, though some species like the Galápagos fur seal live in tropical regions.
