keyhole + limpet
The noun is a straightforward compound combining 'keyhole' (a hole for a key) with 'limpet' (a marine animal), so the meaning is a limpet that has a keyhole‑shaped hole in its shell. This descriptive, form-based composition follows common compounding patterns and would be inferable to a B1 learner who knows both constituent words.
Etymology
Keyhole limpet is a small sea animal with a cone-shaped shell that has a hole at the top like a keyhole. The word limpet means a small shellfish that clings to rocks, so the picture of a 'keyhole' in a 'limpet' shell explains the name and helps you remember it.
