Morphology
Pinnotheres + ostreum
The genus name 'Pinnotheres' clearly signals a small crab that lives in shells, and the species epithet 'ostreum' plausibly derives from Latin 'ostrea' (oyster), so the compound denotes a Pinnotheres species associated with oysters. However, 'ostreum' is not a common English word and recognizing the oyster link requires knowledge of Latin roots or taxonomic naming conventions, which a typical B1 learner would not reliably have, so the relation is only partially transparent.
Etymology
Pinnotheres ostreum comes from the crab's habit of living inside oysters. The second part, ostreum, comes from an old word for 'oyster', so the name is a simple memory hook for a tiny crab that lives in an oyster shell.
