monkeys uses unnatural defense, snake use natural offense

It often strikes me when we say something like "the species developed resistance to this" that it really means "a whole lot of the species died." The way we say it so often implies that individuals are sitting around strategizing and planning how to evolve. We even sometimes say "evolutionary strategy." But it's actually that a whole lot of individuals died out and a few survived through a lucky fluke that was then passed on.

@@oldcowbb While there is no agency, there certainly is causality and reason. Hence, talking in these terms is not completely unjustified, albeit potentially misleading as it presents it the wrong way around. A bit like, "It is, therefore it must be". The other, probably even more challenging aspect there is to it is the limitations of language itself (which certainly stems from the modus of perception you already pointed out). Personification of inanimate aspects of reality is not always a mere stylistic choice, but might sometimes become a necessity, especially when you're trying to jam-pack as much information as possible into a 10 minute long video, or---in stark contrast to the verbal debauchery I'm currently indulging in---strive to keep your sentences short.

Luckily a local man saw what was happening and ran over shouting, he hit the snake with a stick and explained to my parents what it was. Venom in the eyes is not as harmful as a bite but still frightening and painful and occasionally blinding. The bite is dangerous as it is very venomous. Poor wee snake was probably just nervous and scared.

I think another interesting point in this "arms race" is that Austrlaian taipans, which are an asian species originally, and possibly related to sea snakes, have a venom that is SPECIFICALLY DEADLY to PRIMATES... except... Australia HAS NO primates... so their venom's evolution was a direct response to pressure from Australia's indigenous HUMAN population.

6:22 "honey badger don't care" that's one way to put it😂

It is so cool how we evolved together.

Blake’s bad jokes make my day better ❤

I am not one of those people who wants to own snakes and fondle them, but I CAN appreciate how beautiful they are. Venom is a real drag, though.

Given that its snakes, odds are the frequent use of achilles heel is anatomically accurate.

Hi Blake, Great video. While I am not a fan of snakes, you held my keen focus all the way through it. Wait, a Spitting Cobra can hit a target 2.5 meters away? Damn! In other news, I have a grandson who is also named Blake. How cool is that?

Thank you so much!

Another excellent vid. :)

Excellent video

OT question: Many Blue Butterflies are "ant reared", or raised by ants, but info on which or how many species are thus is hard or impossible to find. Are my own lovely Blues in Arizona ant reared? We have five species here but no info on rearing. Please help!

Are there myrmica ants in Arizona? Cause that’s the genus of ants that raise blue butterflies in Britain. As for the Americas even if there are myrmica ants I have no clue.

The scale of the punning in this episode is just incredible.

@@dr.kraemer I'm sure if you look hard enough you'll find something asp-irational.

Fascinating

Steve Irwin taught me about the "Spitta's", and I was hoping they would be brought up!

Any video about snakes is a Thumbs-Up by default.

Thank you.

We should respect these deadly animals who give chills to the bravest beast. If it wasn't for these venomous snakes so many animals like humans would have easily imfested forests and lived there with no fear, while humans have found ways to still destroy forests, it is only when they organize it by doing mass clearing of forests, but a general surge of people won't happen because of these deadly animals, in a sense they are protecting the ecosystem by deterring humans and other outsiders. That's why in India we respect them a lot and consider it divine.

I've been waiting for this vid since I heard about it from the Bizarre Beasts episode 🤣

I’ve never heard the word elapid stressed that way before. I’d always heard it stressed the way he did when he said it as the family name elapidae.

@shanerichins3532, there is no such thing as an elapid, Elapidae is no longer a valid family, it is now replaced with five different families that are mostly not closely related to each other, which are Micruridae (Coral Snakes), Hydrophiidae (Sea Snakes), Acanthophiidae (Oceanian Asps), Bungaridae (Land Kraits and African Garter Snakes), and Najidae (Cobras and Mambas), Elapidae is no longer recognized because its original type genus Elaps is invalid, harlequin snakes are now thought to belong to the family Atractaspididae with their original genus Elaps now being renamed Homoroselaps, for this reason, the Elapidae family is now abandoned.

PBS Eons - Do not go out and play with venous snakes. They may look like fun, but they are not. ***the more you know theme plays***

Speaking as a fellow 'neurospicy', I never would have guessed, Blake.

7:33 if not friend, why friend shaped?

Love the content, also I could listen to him read a phone book.

Please do sea snakes! So, so many questions!

It should be noted that a limbless animal developed a ranged weapon. If it wasn't already real, nobody would believe something so absurd was possible.

Thankthssssssss for all the wonderful ssscthience ssshthowssss 👏👏👏 And thank you eonthhhhologistsssssss / patronsssssssss 🙏🙏🙏

Cobra have venomous fangs Early hominin proceed to poke with longer sticks Cobra evolved a Spitting Attack to shoot out the venomous liquid😅

When Hank was saying his promo at the end I couldn’t help but think his partner for that show, Sarah Suda, has the best name for a news caster if people evolved from crocodilians. I think I’ve been watching too Many crocodile evolution videos. 😅

In Australia we have only 23 snake species (according to Wikipedia) that are not venomous, and in the southern states basically all the snakes are venomous

Thanks!

My ancestors developed the definitive anti-snake characteristic of tap-dancing on the head of such critters.

7:30 *sets down the cobra I found* 🤔

Will there ever be another mysteries of deep time season? PLEEEAAASE 💗

Evolution is so fascinating
