Morphology
flashlight + fish
The meaning 'a fish with a light-producing organ' is directly derivable from combining 'flashlight' (a light-producing device) with 'fish' (a fish); the noun+noun compounding pattern in English typically describes a salient property of the head noun. A B1 learner who knows both constituents would reasonably infer that this is a fish that produces or shows light, so the expression is transparent.
Etymology
Flashlight fish gets its name from the bright light under its eye that looks like a tiny flashlight on the fish. That's why the name means 'a fish with a light under its eye'.
