A small, tropical marine fish with a hard, box-shaped body covered in bony plates rather than regular scales.
Compound of 'box' (its geometric, rectangular body shape) and 'fish' (the animal). Scientific name Ostraciidae; the term is descriptive of its appearance.
Boxfish are tiny engineering marvels—their rigid, box-like skeleton is built from bone plates that can't bend, so they've evolved to swim by rowing their fins like oars instead of wiggling like normal fish!
