This fascinating cephalopod is found in tropical and subtropical waters around the globe, and its delicate, fragile shell has captivated scientists and naturalists for centuries.
Description & Characteristics
Argonauta nouryi is a relatively small octopus, with females reaching a maximum mantle length of around 15 cm. The males are significantly smaller, typically measuring only a few centimeters in length.

Habitat and Occurrence
Argonauta nouryi is a pelagic species, meaning it inhabits the open ocean, rather than being associated with the seabed. These octopuses are found in tropical and subtropical waters around the world, primarily in the epipelagic zone, which extends from the surface to a depth of approximately 200 meters. They are most commonly observed in waters with temperatures ranging from 15 to 25 degrees Celsius. Argonauta nouryi is a frequent inhabitant of the Indo-Pacific region, including the waters of the and the . The species is also found in the Atlantic Ocean, specifically in the and .
