Old Octopi

I was looking for images of vintage octopuses and found these pictures.. along with a Japanese illustration of lady-octopus sexy stuff, which um, I won't include.

The internet also tells me that all octopuses are venomous, but only the blue-ringed octopuses are known to be deadly to humans.  Octopuses have three hearts, and their beak is the only hard part of their body (Here is an anatomical diagram of our tentacled friend).  They can defend themselves with camouflage, ejecting thick black ink to aid escape, and autotomising limbs (self amputation).  The crawling arm serves to distract the predators..
