The Awesome Argonaut Hians

The Paper Nautilus, known as the Argonaut Hians are actually a pelagic octopus. 

The Awesome Argonaut Hians

They spend their entire lifecycle in the open ocean and never settle to the sand. The female builds a shell to brood her eggs which is often called an egg case. The male Argonaut Hians are much smaller than the female in one of natures most extreme examples of sexual dimorphism. The female can reach the size of a baseball while the male never exceeds the size of a large garden pea. They spend most of their time in deeper darker water’s where food or feeding opportunities can be scarce but at night all of that changes.

As the sun sets, planktons begin a vertical path of migration to disperse and feed in the shallow. Subjects like the Argonaut Hians are a great example of some of the predatory animals that follow this migration, much like a pride of lions might follow a herd of gazelles.

Finding either one of them riding a jellyfish or other flotsam isn’t an uncommon behaviour and makes for the ultimate in photo/video ops.

Despite their appearance, the female paper nautilus is a fast-moving subject. When they are moving at full speed, it is impossible to keep pace.
