Viperfish

About the Viperfish

They have the largest teeth relative to head size of any fish. Their teeth are so long they do not fit inside their mouth and curve back toward their eyes. They have a hinged skull that allows them to swallow prey larger than themselves. They have bioluminescent photophores along their belly. They can go days between meals. They use a modified dorsal fin ray as a lure. They are found in all oceans. They are one of the fiercest-looking deep-sea predators. They can live 30+ years. They migrate vertically nightly. Over 10 species exist.
