How many octopuses are in Captivity?

Estimating the exact number of octopuses in captivity is challenging due to the lack of centralized reporting and the diverse locations where they are kept, including aquariums, research facilities, and private collections. However, it's known that many public aquariums house octopuses as part of their exhibits and educational programs. The number can fluctuate widely based on breeding, species, and institutional policies. Overall, while specific numbers are hard to determine, thousands of octopuses are likely kept in captivity worldwide.
