fuzzynecromancer asked:

why is taxonomy so yiffing weird? animals be like "we could pass for each other in a poor light but one of us is a specialized shrew and the other is a very big nematode"

bogleech answered:

basically as visually-oriented beings we judge everything based first on surface aesthetic but organisms are really more defined by the microscopic level so we keep being surprised.

I NEVER get over the fact that jellyfish, or at least some sot of cnidarian, evolved into basically a skin disease at some point.

bogleech

Myxozoa or “slime animals” are single-celled organisms that grow in the tissues of fish, causing tissue death or serious deformities in the host until they grow into a visible “plasmodium,” just like a slime mold.

They were once thought to be protozoa, but genetic sequencing proved they were cnidarian animals just like jellyfish, sea anemones and corals.

Their drifting “spore” phase even has a microscopic harpoon-like structure derived from what were the stinging cells of their ancestral jellies.

Here’s a bunch of them!

bogleech

Now what’s even MORE absurd is when genetic sequencing proved a type of parasitic “worm” to be a myxozoan.

image

So this “worm” is back to being a multi-celled animal that can slither around on its own and has a body symmetry completely unrelated to that of any other cnidarians.

Some sort of jellyfish over millions of years evolved back down to a single-celled form, and then one of those single-celled organisms re-evolved a more animal-like body again, completely and totally different but still genetically a cnidarian! Still equipped with the harpoon cell, too!

Anonymous asked:

Has anyone here seen the recent short animated dinosaur film "Sharp Teeth" by Dead Sound? If so, what do you think of it?

ask-palaeoblr answered:

I love it. It’s beautifully animated, adorable and also REALLY SAD but as well as that it’s a great deconstruction of how carnivorous animals are often villainised in stories when nature isn’t about good vs evil species. Since it’s about predation and things, warning for animal death.

Accuracy-wise, the dinosaurs are all really well made and carefully reconstructed, and although there are a couple of minor issues with proportions everything else is really great. The Triceratops even has the correct configuration of toes on its front foot!

So yeah you should watch it.

Ironically, Bojack has said things about Alaskans.

Interestingly enough, here’s a quote from Raphael Bob-Waksberg from his interview with Terri Gross on NPR talking about making jokes that are not politically correct/going too far and how he got called out by a native Alaskan: 

Another joke about somebody that I am not is we have a joke in Season 2 - and BoJack is a very boorish character. And we had a gag where he’s going on this press tour. And everyone’s worried that he’s going to say something offensive. And they’re going to Alaska. And he has a line about, we’re going to Alaska. What am I going to say that’s going to offend a bunch of inbred, Eskimo, blubber munchers? - is the line. And, you know, on paper, I can defend that joke. And I can say, no, the joke of that is not on the Alaskans. It’s about how stupid BoJack is and how he doesn’t realize - and clearly, the way it’s set up is, oh, he is saying this offensive thing and not even knowing that it’s offensive. So I feel like technically, we are in the right on this joke.

But someone tweeted at me a couple years ago and said, you know, I am a Native Alaskan myself. And I was watching your show. And there is not a lot of representation for my people on television. And to watch this show make this joke about my people and knowing that this was the only reference in the show of my people and knowing that nobody who works on the show is of my people, it hurt. And I cannot then say, no, but you are wrong because I did it correctly (laughter). You misinterpreted it, so you are wrong to be offended. I have to hear that note and go, oh, you’re right. Maybe we weren’t as careful about that as we should have been.

13lizardsinatrenchcoat asked:

Why do mantis shrimp eyes Do That (blink horizontal and look like they have three oval pupils)?

montereybayaquarium answered:

Great question! That horizontal “blink” and the three oval pupils are various tricks of the light as it bounces off the mantis shrimp’s triple-banded, highly-faceted eyes! 

image

Mantis shrimp do not have eyelids, so they don’t blink—but they do clean their eyes frequently to keep things 20/20!

image

The eyes of mantis shrimp have three bands, each with a focal point. One mantis shrimp eye is therefore tri-focal, meaning they have depth perception with just one eye! Those three focal point “pupils” appear when the eye is looking toward the camera.

image

Each band is sensitive to different types of light, including polarized light, allowing mantis shrimp to see and communicate using visual signals that play across a huge visual spectrum! 

image

Thanks again for the great question!

alphynix

This optical illusion is known as a pseudopupil, and it can also be seen in the eyes of many other arthropods – including fiddler crabs, praying mantises, and dragonflies.

Mantis shrimps get extra cool points for having three per eye, though!
