Crocanura

Crocanura are a quite scary predator of the ravnican wildlands in the Gruul Territories and even in some shallow layers of the undercity. They are essentially giant frogs with better armour and 4 eyes. these eyes are special in that one set sees regular light and the other sees magic. This peculiar evolutionary trait emerged from its preferred diet of birds of paradise.
