Morphology

sea + spider

The compound is directly composed of 'sea' (marine) + 'spider' (spider-like creature), so its meaning as a spider-like animal that lives in the sea is immediately inferable from the constituents. This straightforward noun-compounding pattern is cross-linguistically common and would be understandable to a B1 learner who knows both words.

Etymology

Sea spider gets its name from the way it looks: a very small body with long, thin legs like a spider living in the sea. So the name means 'a sea creature that looks like a spider'.
