Creepy Critters: Marine Life Surfaces for Halloween

Claws, spines, spikes, tentacles, and fangs. Aliens, monsters, and ghostly apparitions glowing in the night. Marine life forms have some of the best looks for Halloween—no costumes needed. From freaky fish lurking beneath the surface to creepy crawlies of the deep, meet some of the sea’s strangest and most haunting characters. Then tell us below: Which ocean creature scares you the most?

The aptly named fangtooth fish has long, menacing teeth. The fangs are so long, that they aren't able to close their mouths! They are able to eat crustaceans and fish, despite the large teeth. But this "monster of the deep" is not as scary as it may seem--it only reaches about 17 cm (6 inches) in length.
