I believe 'Cuddle Fish' are the same as 'Cephalopods', but I could be wrong.. Using that name for searching might be better. You will find alot more info when searching for Cephalopods.
They're lifespan is about 2 years. And, if you're attempting google searches, you'll have an easier time using 'cuTTlefish'. They're not cuddly like teddy bears.
