The chambered nautilus (Nautilus pompilius) is a species of cephalopod (octopuses and the like) found in the south Pacific ocean. They are carnivores that have 90 tentacles to help them catch their prey. Nautiluses are scavengers and have been described as eating “anything that smells”.
This species of nautilus is also called the pearly nautilus because the interior of their shell has coating that we know as mother-of-pearl. When cut in half, their shell also shows a nearly perfect equiangular spiral.
Due to overfishing for their shells, nautiluses are at risk of becoming endangered.
Scientists are currently studying the world’s population to determine if conservation efforts are necessary.
