means A camouflaged, bottom-dwelling fish bristling with venomous spines, built to ambush prey and deter predators by looking exactly like the seafloor until you touch it.

from Straightforward compound English: 'scorpion' + 'fish,' naming the creature for what it does, not what it is — the venomous dorsal and fin spines deliver a sting reminiscent of a scorpion's tail. 'Scorpion' itself traces back through Old French and Latin scorpio to Greek skorpios, an ancient word for the arachnid whose name became shorthand across languages for anything armed with a hidden, painful sting.
