Why are they important?
The blue ringed octopus is most commonly used for medical/psychological research. Scientists are most interested in the neurotoxin as an aphrodisiac and its ability to inhibit or produce action in neurons. They are also a high value luxury item, one sold for over $4000. Because it lacks an ink sac, it has become popular in aquariums. Another popular use for the octopus is its venom. One of the major industries in Australia is venom, and this octopus is one of the major contributors.
