Biologist Rich Ross, who once worked in the commercial aquarium trade, proposes a private-sector solution to the information drought: âa cooperative of responsible saltwater aquarium dealersâ that could both track the trade and promote sustainable practices. But much remains unknown about them, especially about mimics, including how many inhabit the shallow seabeds off Sulawesi, Indonesia, and other Indo-Pacific islands where theyâre found. During this time, it leads a solitary existence, breeding only one time. Some, such as the California two-spot octopus, appear to fare relatively well in captivity.

"If anything,â says the sales manager at one aquarium-animal import company who requested anonymity because he was speaking without authorization, âIâve seen a downturn over the years.".
