How do you age an octopus?

Still Waters

Recommended Posts

The question of how to tell how old an octopus is has been at the forefront of researchers' minds as they seek effective strategies to help age these animals, and thereby work to combat issues associated with overfishing and the growing demand for commercially harvesting octopuses for consumption. 

Octopuses typically have pretty short lifespans, depending on the species. They may live as little as 6 months to a year – the common octopus (Octopus vulgaris) has a lifespan of 1-2 years in the wild while the giant Pacific octopus (Enteroctopus dofleini) can live for 3-5 years. But how do you go about telling the age of these eight-armed cephalopods?

My first thought was "to get him started smoking at an early age"... ;)
