Macropinna microstoma - a fish with transparent head

M. microstoma inhabitates depth from 600 to 800m. The fish normally hovers and moves very slowly in the water and when its prey arrives M. microstoma does one or few sharp moves to catch it. As seen from the image above, this creature is famous for its transparent cranium and its eyes which could be directed straight forward or in different directions, said in other words - this fish is able to see through its own cranium.
