Morphology
This is a straightforward adjective + noun composition: 'common' (typical/frequent) modifies 'blackfish' (a small dark cetacean), so the phrase simply denotes the typical or frequently occurring blackfish. Such modifier + noun combinations are fully compositional and cross‑linguistically familiar, so a B1 learner who knows both words can infer the meaning.
Etymology
Common blackfish comes from what fishermen long ago saw: a small, dark whale that swims in tight groups and looks a bit like a big 'fish'. They used black for its dark colour and fish because it behaved like a fish, and 'common' showed it was the one seen most often, so the name now tells us it's a dark, small whale often led by a large male.
