fascinating facts

 They are the only octopuses that are venomous to humans and have enough venom to kill up to 26 humans within minutes. 


Both the male and female die during the reproductive process. The male dies immediately after mating. The female will then lay up to 100 eggs which she will protect with her life during the 1-2 month gestation period though out this time she will not eat at all which ultimately results in her dying from lack of strength.


 Despite there beautifully bright colours they can only see in black & white.
