Hydras: Our Immortal, Tentacled Friends

While humans age and die (which is kind of a bummer), it looks like hydras will stay young and fertile forever. Why is this? And what can we learn from these tentacular microscopic organisms?

I currently have a tank setup for green hydra, they coat almost every surface of hardscape and even the substrate like a mat of living grass.

They are the bane of my existence when it comes to the shrimp tanks but as a separate species display they are pretty amazing creatures.

Ageing is nature's way of saying : it's easier to build a new body from scratch that to fix this old thing

If you cut a hydra it will grow two heads. You just have to cut it perfectly down the middle (between the eyespots) the right distance and wait a few weeks. This was the coolest thing I did in comparative anatomy.

I was tempted to just download an entire SciShow episode and re-upload it, but instead of putting the actual video with Hank there, I'd just put a repeating image of the Hydra there and at the end it'd say "How you like me now Hank? We CAN host YouTube shows!"

Who else is here because they know hydras are in the shot?

"I would like to see it host a YouTube show..."

Yeh and guess what!! Those things are in the jabs they are pushing on the world!! And there is a way to live forever, believing in the LORD and SAVIOR JESUS CHRIST!! Thats how!! Being a good person doesn't save anyone!! Its what you believe that saves you!! For if you confess with your mouth the LORD JESUS, and believe in your heart that GOD raised him from the dead, you will be saved. Romans 10:9

Who is here in 2021 to look at our new "body buddies"?

[lustralustra]

So much experiements with bio much combination to alter a d.n.a sequence which will be compatible with our own existing d.n.a.

[patriciaebert]

So..why did they put it in our jabs ? What benefits could it have ? Or side effects ? The one scientist of one of the three makers of the jab...found it in all bottles studied...so ..is that bad..? Or good ??
