I spent a couple of hours making jellyfish tentacles. Actually, that might not be what they are at all. But not being a marine biologist, my knowledge is wispy. Rather like a floating tentacle. Still, the dangling strings that float behind the creature's head are part of what makes them intriguing. And why my granddaughter aspires to be one. 

It is interesting that ignorance about their name and function does not preclude me from ruffling sheer fabric to replicate them on a little girl's costume. 

A collection of such creatures is called a bloom. Which sounds friendly enough, and yet hides the fact that one species is the most poisonous animal inhabiting the oceans. 

Jellyfish are bloodless, brainless, and boneless, but these anatomical lacks do not slow them down. They have existed for millions of years, even escaping the effects of mass extinctions. Not only that, one species is believed to be immortal because it can reverse its life cycle and grow young again. Scientists give it the fancy title "transdifferentiation", but that doesn't fool me. I think we all have a crack at it. 

"Then Jesus called a little child to Him, set him in the midst of them, and said, “Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven. " Matthew 18
