Coelacanth: "Ah yes, I will live in the twilight zone of the ocean."

Also coelacanth: "It's too bright out here. I'm going to a cave or something."

I had a massive surgery last year in August. And afterwards I was so stressed out I kept having panic attacks. But I found laying there and focusing on listening to hank (specifically) talk about scientific things, really helped calm me. Thank you Sci Show, and thank you Hank!

"Mom, I can't find the potentially extinct species!"
"Have you checked the limestone?"
"Oh! There it is"

That moment when you realize that the stegosaurus was as ancient to the T-Rex as The T-Rex is to us...

Scientists: "65 million years ago, we lost the dear Coelacanth."
Coelacanth: "QUIT TELLING PEOPLE I'M DEAD"
Scientists: "Sometimes we can still hear its voice!"

THANK YOU THANK YOU FOR MENTIONING MARGERY!!! I have watched so many documentaries that never mention her, giving all credit to the fishermen for the discovery and identification!

When you said 10 km long Lord Howe Island... while showing the Lord Howe Island Stick Insect, I got really scared for a moment.

Please, please, please, show the pictures (of the animals) more often. I like to see it while I think about it. If I can’t picture it I don’t know what I’m learning! Haha merry Christmas!

I promise that if I ever become a musician, I'll name my first album "tadpole fannypack"

Scientists: Did you die?
Coelacanth:Sadly, yes...
Also Coelacanth:But i lived!!!

[davidbuschhorn]

They called it a Rock Rat when they could have named it the Laos Mouse?

[ahmedwael]

Now if only we could find a lost dinosaur colony

The coelacanth has always been my favorite ancient organism as a kid. I dunno if it is because of its anatomy or the fact that it was the first time I've heard of it being a living fossil back then, but it always fascinated me as a child.

I have another fish for this list! The robust redhorse sucker, a freshwater suckerfish that lived in the Southeastern US, was thought to be extinct until a woman in Georgia found 2 big ones in a stream on her property. These are now my husband's favorite fish. 😊

500 Million year old Mollusc: This is what peak performance looks like

[tinkerspell]

I really really hope the Tasmanian Tiger is still alive. :) Some intense forest down there.

[jemmapellemma]

So... Coelacanth are literally prehistoric cave-fish? Man, that ROCKS! XD

[neonmangoz]

Well, if Coelacanths never really changed...

*That would explain why Relicanth never evolves*

"The ten kilometer long Lord Howe Island Stick Insect."
Please tell me I'm not the only one who's brain made that jump...

I encourage folks to look up #6 - For a bug these are extremely caring for each other. Such as the male will cradle/hug the female and so on. Especially worth reading for those that think bugs are all Eat/Mate/Die type animals.
