Nautiluses love dead meat. Nautiluses love to meet new nautiluses. Nautiluses are big. Some nautiluses are small. This is one of the smallest nautiluses caught on video. We don't know exactly where or when nautiluses lay eggs OR where the hatchlings go right after hatching OR how many hatchlings survive to adulthood. Edit: The tin can you see is actually full of dead fish that we use as bait to attract the nautiluses to the camera. The tin can comes up with the camera and is not left in the ocea
