Mar'kuu
Mar'kuu is an extict sea animal, native to Cardassia Prime. It belongs to the same class as Cardassians (evolutionary higher level of reptiles). Its extinction is related to high pollution of seas and oceans on Cardassia Prime. The pollution was direct result of heavy industrialisation from 2320s onward (old Federation calendar).
Mar'kuu breathed air and was a carnivore.
