Morphology

sea + mat

The meaning is directly compositional: 'sea' (saltwater) + 'mat' (a mass or tangled growth) yields a mat-like growth found in the sea. A B1 learner who knows both constituents can infer this refers to a mat-like aquatic organism or growth attached to stones or seaweed, following a common noun–noun compounding pattern.

Etymology

The noun sea mat may come from the simple image of a flat 'mat' on the sea. People thought the creature formed a soft mat or 'carpet' stuck to rocks under the water, so today sea mat means those moss-like animal colonies.
