Morphology

three-spined + stickleback

The phrase is fully compositional: 'three-spined' plainly means 'having three spines' and 'stickleback' names a small fish with a spiny back, so the combined meaning is a stickleback that has three spines. This follows a regular number + adjective + noun compounding pattern that is literal and cross-linguistically transparent, so a B1 learner who knows the constituents would understand it.

Etymology

Three-spined stickleback is a picture of the fish: three-spined means it has three sharp spines on its back and stickleback is a name for a 'small, bony-backed' fish. So the name simply tells you it is a small fish with three sharp spines.
