I was thinking this days ago. Locust drones, grenadiers, therons, kantus, berserkers? All have a scientific name? I mean if drones, grenadiers and therons are the same branch family that means the ranks are species. I mean this: Grenadier (Saurohomus robustus). Theron (Saurohomus venatorius). And what about this: Oviparous (Eggs like reptiles or birds), Viviparous (Mammals) or Oviviparous (Sharks and mosasaurs)?
