The Ozark cavefish (Amblyopsis rosae) is a small subterranean freshwater fish native to the United States. The fish has no pelvic fin; the dorsal and anal fins are farther back than on most fish. It has only rudimentary eyes and no optic nerve.

A new study finds that Mudskipper fish carry water in their mouths in order to eat prey outside of water. As seen in the video below, the hidden water is expelled at the moment of eating and it serves as a suction to move the water and their meal back toward the esophagus. The water suction, or “hydrostatic” tongue, may serve as the evolutionary bridge that allowed our aquatic ancestors to begin feeding on land.

Penguins may lack teeth, but they have backward facing spines in their throats that grip and guide fish down.

Apparently, the archerfish from the family Toxotidea, literally "spit" to catch their prey. It is like a frog, but upgraded, in the sense that it catches insects and land based prey without a weapon, or a physical means. It just teleports its prey from above water, into the water by knocking it out via shooting water droplets. The missile strength of the water droplet is created and altered based on how far and how big their prey is ...
