Thanks for this fantastic and enthusiastic story about such fascinating animals, good luck Danna, keep enjoying your Cephalopods!! With warm greetings from the Netherlands, Caroline van der Mark
It can be very difficult to distill down a subject you've spent the majority of your life studying into one lecture. I enjoyed her presentation because it was very relaxed and approachable.
It's not that cephalopods are on the way up, it's that we're eating our way through all the tasty fish, and once they're gone, we'll eat all the cephalopods, too. And when they're gone.... well, there'll only be jellyfish left, and they don't taste nice, I think. It's very sad.
Danna is so full of life & ecstatic wonderment at cephalopods, it's truly infectious! That's why we had to invite her for an in-depth chat for an episode of Earth Ideas, to hear more squid & octopus facts and ask her all the questions we could think of.

Now we learned, because of the find of Nectocaris from the burgess shale from ca. 500 to 505 years agoe, that the earliest cephalopods had no shells but already two tentacles and so obviously didn't evolve from shell wearing snails. I was surprised she didn't refere to nectocaris.
Because of more complete fossil founds the final reconstruction of Nectocaris' body plan hit the news only 2 or 3 years agoe - I guess that's still a "now". Nevertheless, you're making a good point about those eyes here,
My girlfriend always calls me a nerd because I read at least 2 books a week and watch 45 minute cephalopod talks on RUclips. I have no valid defense of her assertion.
@@christinestill5002 There were mammal-like reptiles before dinosaurs, but so far we have not found any fully mammal fossils. True mammals did coexist alongside dinos for nearly their whole span of existence.
No. There were mammal-like reptiles, therapsids, before the dinosaurs, but so far we have not found any fossils of true mammals pre-dating the dinosaurs.
Refreshing to see someone so enthusiastic about something like this.
Greatest Celph talk ever. Interesting
Excellent talk and great questions.

People should really leave nautilus alone. We are lucky to see them alive.
This is beautiful.
So good!!
Great subject, yet an overwhelming sporadic presentation

MOLTEN ROCK SHALL RISE UP RISE UP
Race to rise up, rise up high
I love you.
I wonder if the song was inspired by this presentation.

cool stuff!
I was watching John Oliver and it recommended this. I mean, I can see the resemblance, but still...
Athanasios Kamtsiou same....i thought this was gonna be comedy.

Not right. Nectocaris is not a "now" thing. It's old news. And its eyes scream arthropod.

Tell her you're an octopussy.
No defense needed. Own it. Nerds rule.
Nautilus & cuttlefish are so amazing. Def pls do not buy any marine animal products obviously
IKR??!?!?
5:15 is that nigga really eating a salad during this presentation at the bottom left?
When the plankton died, these shelled nautiloids all died if that is what they ate.
But plankton still exist. Do you mean the particular species of plankton that they ate all died out?

There were mammals before dinosaurs.
William Hepfer
She never said that there were mammals before the dinosaurs.
William Hepfer SURE there were.....duh. Let me get my 3rd grader to explain why you're mistaken!

damn, this is pretty cool! but not as cool as dinosaurs sorry hahaha
Couldn't she dress up even a little? Maybe wash her hair?
couldn't you just read and get as smart as her?
pyrrho314 well said!
pyrrho314 good presentation but could have washed her hair...
Brian Boru Seriously? That's what you take from this?
Talk about being rude :|
Maybe it is washed and deliberately styled that way. Or could she have just rushed over from a scuba dive and not had time?
