Animal of the Week: Blue Ringed Octopus                                              11/19/25

The blue-ringed octopus is very poisonous; it is one of the most poisonous animals on earth. The venom is 1000 times worse than cyanide. It has a painless small bite that can kill 26 adults in minutes. The octopus can be 5-8 inches long, or 12-20 centimeters long. The blue-ringed octopus lifespan is around 2 years; and their diet consists of crabs, shrimp, and small fish. They live in shallow coastal waters in the Pacific and Indian Oceans, from Japan to Australia. Like most octopi, the blue-ringed octopus has 3 hearts. I hope you learned something new about the blue-ringed octopus!
