Examples
- The order Octopoda is a diverse group of soft-bodied cephalopods that includes octopuses and the paper nautilus.
- The class Cephalopoda is divided into two main subclasses, the Ammonoidea and the Coleoidea, with the latter encompassing the order Octopoda and its relatives.
- Some scientists consider the order Octopoda to be a natural, monophyletic group that arose from a common ancestor, but others propose alternative classifications.
- In the order Octopoda, the shell is typically reduced or absent, with some exceptions, such as the paper nautilus, which has a thin, calcareous shell that serves as a buoyant, protective device.
- The unique body plan of the order Octopoda has allowed these animals to thrive in a variety of aquatic environments, from shallow tide pools to deep-sea ecosystems.
