Morphology

teleost + fish

The phrase is fully compositional: 'teleost' denotes a subclass of fish, so 'teleost fish' simply means 'a fish belonging to the Teleostei.' This subtype-specifying noun+noun structure is a common, transparent pattern cross-linguistically, so a B1 learner who knows both constituents would readily derive the meaning.

Etymology

The name teleost fish may come from old Greek words teleios 'complete' and osteon 'bone', which gives a simple picture of a fish with a solid bony skeleton and a strong jaw. That's why the name now refers to the many modern bony fish with a well-developed backbone and jaw.
