Members of Panthera are distinguished by morphological features which enable them to roar (link)
Panthera includes Lions, Tigers, Leopards and Jaguars. The name comes from the Greek, pan = all, ther = beast/animal (because they can hunt pretty much what they like!)
The ther root also gives us the words:
- Theropod (beast-foot) – a group of bipedal dinosaurs including most of the nasty/cool ones in Jurassic Park
- Therianthropy (part-man, part beast) – the most well-known example we have is Lycanthropy (Werewolves) but as a term it also includes things like animal-headed Gods, Centaurs and animal spirit guides
- and most curiously Treacle, which comes to us via French and Latin from the Greek word Theriac (pertaining to venomous beasts) and means antidote, a now obselete definition of treacle
