Avoid These Mistakes When Using León marino

Confusing león marino with foca

Incorrect: Mira esa foca haciendo trucos. (pointing at a sea lion)

Correct: Mira ese león marino haciendo trucos.

Foca means seal (earless seal) — sea lions have visible ear flaps and can walk on their flippers, which distinguishes them from true seals in both biology and Spanish vocabulary.

Incorrect pluralization

Incorrect: Los león marinos están en la playa.

Correct: Los leones marinos están en la playa.

Both words in the compound must be pluralized — león becomes leones, and marino becomes marinos, following standard Spanish plural agreement.
