Do baby octopuses eat their mother?
Octopuses are serious cannibals, so a biologically programmed death spiral may be a way to keep mothers from eating their young.

What is the lifespan of an octopus?

Is Octopus intelligent?
Octopuses have demonstrated intelligence in a number of ways, says Jon. ‘In experiments they’ve solved mazes and completed tricky tasks to get food rewards. They’re also adept at getting themselves in and out of containers. There are also intriguing anecdotes about octopuses’ abilities and mischievous behaviour.
Does an octopus feel pain?
Octopuses Not Only Feel Pain Physically, But Emotionally Too, First Study Finds. An important new study suggests octopuses are likely to feel and respond to pain in a similar way to mammals – the first strong evidence for this capacity in any invertebrate.

How many eggs does a Briareus octopus have?
O. briareus, on the other hand, lays approximately 500 large eggs which hatch into benthic young (Sweeney 1992). This fact is important as the large-egged octopuses are much easier to rear. Occasionally an octopus will lay eggs in captivity. If the hobbyist has had the octopus for a long time, the eggs will be infertile.

Why do female octopuses not hunt for food?
Females in the early stage of brooding continued to eat but didn’t actively seek out food. This could mean that the neuropeptides affect the amount of energy the octopus expends to find prey. Certain muscles may begin to deteriorate so the octopus physically can’t hunt or digest food.
