For generations, scientists have relied on a handful of organisms to study the fundamentals of biology. The usual suspects -- fruit flies, zebrafish, and mice, among others -- all have short lifespans, small body size, can be bred through multiple generations in the laboratory, and have been developed for genetic investigations. These research organisms leave out a whole swath of biological diversity and scientists have lacked access to a cultured octopus laboratory organism -- until now. Introducing the pygmy zebra octopus (O. chierchiae).
