What were the feet and mouth of the sea beast of Revelation 13 like?

His feet were like a the feet of a bear and his mouth was like the mouth of a lion

I stood upon the sand of the sea, and saw a beast rise up out of the sea ...

And the beast which I saw was like unto a leopard, and his feet were as the feet of a bear, and his mouth as the mouth of a lion Revelation 13:1-2
