Morphology

sea + lion

A B1 learner who knows 'sea' and 'lion' will naturally interpret 'sea lion' as the marine mammal; the internet sense (a tactic of persistently requesting evidence to frustrate opponents) is a cultural, figurative usage that is not derivable from the literal parts. This meaning is idiomatic and context-specific, so learners need prior exposure rather than compositional inference.

Etymology

Sea lion comes from early sailors and coastal people who heard the animal's loud barks and saw its big head and mane-like look, so they imagined a lion of the sea. That's why the name now means 'a large eared seal'.
