How does a Nautilus eat?
Food is captured by its retractable tentacles and passed to its mouth where a beak-like jaw tears it into pieces. Its radula, a file-like feeding structure, further shreds the food before it is swallowed.
Can a nautilus be a pet?
Unfortunately no cephalopod does good as a pet for anyone but an expert or zoo/aquarium. Although octopus and cuttlefish are poor captives, nautilus are bad for completely different reasons. They need a chiller and often bob up and down as movement, so a large, refrigerated, cylindrical tank would be needed.
What animals eat Nautilus?
Natural predators of nautilus include the octopus, which can bore a hole right through the nautilus’ shell to reach its soft body parts in the outermost chamber. Teleost fish, such as triggerfish and grouper, prey on nautilus in shallow waters, and other species such as sharks and snappers may also prey on nautilus.
