When are Pterotrachea finally going to go viral? How does anyone look at this animal and not flip their shit? I first saw them in a BBC documentary when I was a toddler and I still can’t believe a real thing evolved like this, but somehow as soon as I’m done thinking about them they just quietly retire to the background of my memory. Multiple divers say that they have a tendency to follow you around when they see you. :) :) :)

Anatomical guide by request! This animal is technically a snail, but here’s how the parts of its body match up to a more typical snail:

They look like relatively ordinary snails early on, or at least in embryonic development, but as they mature the shell reduces, the mouth stretches out into a proboscis, and the foot flattens into a fin that steers it through the water “upside-down.” It also happens to have EXTREMELY advanced eyeballs for a gastropod!

You know those weird horizontal pupils that goats have?…. they get a lot weirder.   Other places to see my posts: INSTAGRAM / FACEBOOK / ETSY / KICKSTARTER

[nosleep4sam]

I did not know this.

[wardenmcpherson]

I see this at a farm nearby where I like to hang with the goats, but the only time I’ve seen it captured on film was in that recent episode of It’s Always Sunny In Philadelphia where Sweet Dee got trampled in the petting zoo. I guess it is deeply disturbing and kind of underutilized in horror, but I still wish my eyes did that.

Like, seriously, why isn’t this in more movies? Why did I have to make the .gif myself?

[ainawgsd]

In all fairness, human eyes do this too…it’s just harder to tell because we have round pupils instead of horizontal pupils.

i want there to be less information on this post please

[shitboy96]

Felt the need to add that the very last thing isn’t quite accurate, while human eyes can and do rotate, they only do so a few degrees (not sure exactly but something like 15 degrees). That’s why when you turn your head your field of vision rotates too.

Albacore and Blue Headed Wrasse for the ocean asks!

Albacore - Do you collect shells?

Yes I do! I don’t do so very often at the moment, but when I travel further afield I do. Back in Uni we had a field trip where there was a prize for the best shell collection at the end of the week, and I won by a landslide 😅

Blue-Headed Wrasse - Do you have any pets?

Not currently, but soon! I used to keep quite a few animals - crayfish, snails, axolotl, at one point an intertidal marine tank - but I moved house recently so couldn’t have any for a while. I’ve just started getting the aquarium tanks unpacked though, so in a couple months I’m hoping to get some new friends!

scientist voice: today i will be a dick to this cricket 

[onion-souls]

The phrase “exposed to this spider torment” will haunt me

[ventela1]

People in the notes have entirely misunderstood the point of this experiment and what it entails.

It’s not “proving that crickets can be traumatized”. It’s proving that *animals can genetically pass on the stress that a dangerous situation causes, and the offspring will instinctually respond to the same situation without ever having personally experienced it.*

And that’s a big deal for many things, including human psychology.

When Nazis invaded The Netherlands, local Dutch peoples were under extreme emotional and physical duress. The Nazi army took their food for the soldiers, starving the population. They patrolled the streets and harshly reinforced their new laws. Existence was horrible and some parents had to give their children away to wealthier families because they couldn’t feed them anymore. This event is known as the Hongerwinter, or Dutch Famine.

One generation later, the children of mothers who were pregnant at the time of the famine have been proven to exhibit intense reactions to stress, and heightened fight or flight responses. They also experience more obesity because their bodies are prepared for starvation.

Some of these children were never personally exposed to the famine. Their mothers gave birth after conditions had improved, or even after moving to another country. But the effects are there, and those people are now adults who can recognize this and attest that they didn’t experience something else traumatic during childhood. It was passed on in the womb.

You can read about it here: https://www.google.com/amp/s/www.nytimes.com/2018/01/31/science/dutch-famine-genes.amp.html

The Famine Ended 70 Years Ago, but Dutch Genes Still Bear Scars

Babies born during the Dutch Hunger Winter became adults with higher rates of health problems. Now researchers may have found the genetic sw

This is called epigenetics. It’s essential to understanding how the human brain and body works. That our responses to stress can be passed on genetically. That it can show up in how we look physically, our physical health, our mental responses, our instinctual reactions. It’s especially important for people who are in therapy and need to understand *why* they act a certain way before they can actually work on it.

So no, this experiment wasn’t “haha let’s torment a cricket”. I’m not going to argue the potential cruelty of the experiment with people. I just want you to understand what it actually all MEANS.

You know what the most frustrating thing about the vegans throwing a fit over my “Humans aren’t Parasites” post is?  I really wasn’t trying to make a point about animal agriculture. Honestly, the example about subsistence hunting isn’t the main point. That post was actually inspired by thoughts I’ve been having about the National Park system and environmentalist groups.

See, I LOVE the National Parks. I always have a pass. I got to multiple parks a year. I LOVE them, and always viewed them as this unambiguously GOOD thing. Like, the best thing America has done. 

BUT, I just finished reading this book called “I am the Grand Canyon” all about the native Havasupai people and their fight to gain back their rights to the lands above the canyon rim. Historically, they spent the summer months farming in the canyon, and then the winter months hunter-gathering up above the rim. When their reservation was made though, they lost basically all rights to the rim land (They had limited grazing rights to some of it, but it was renewed year to year and always threatened, and it was a whole thing), leading to a century long fight to get it back. 

And in that book there are a couple of really poignant anecdotes- one man talks about how park rangers would come harass them if they tried to collect pinon nuts too close to park land- worried that they would take too many pinon nuts that the squirrels wanted. Despite the fact that the Havasupai had harvested pinon nuts for thousands and thousands of years without ever…like…starving the squirrels. 

There’s another anecdote of them seeing the park rangers hauling away the bodies of dozens of deer- killed in the park because of overpopulation- while the Havasupai had been banned from hunting. (Making them more and more reliant on government aid just to survive the winter months.) 

They talk about how they would traditionally carve out these natural cisterns above the rim to catch rainwater, and how all the animals benefitted from this, but it was difficult to maintain those cisterns when their “ownership” of the land was so disputed. 

So here you have examples of when people are forcibly separated from their ecosystem and how it hurts both those people and the ecosystem. 

And then when the Havasupai finally got legislation before Congress to give them ownership of the rim land back- their biggest opponent was the Parks system and the Sierra Club. The Sierra Club (a big conservation group here in the US) ran a huge smear campaign against these people on the belief that any humans owning this land other than the park system (which aims at conservation, even while developing for recreation) was unacceptable. 

And it all got me thinking about how, as much as I love the National Parks, there are times when its insistence that nature be left “untouched” (except, ya know, for recreation) can actually harm both the native people who have traditionally been part of those ecosystems AND potentially the ecosystems themselves. And I just think there’s a lot of nuance there about recognizing that there are ways for us to be in balance with nature, and that our environmentalism should respect that and push for sustainability over preserving “pristine” human-less landscapes. Removing ourselves from nature isn’t the answer. 

But apparently the idea that subsistence hunting might actually not be a moral catastrophe really set the vegans off.  Woopie.

Found this Ranatra! at a pond last night with @revretch and @xenoplasm, the bubble filter might be a little too intense and making too much current; I think the plant chunk floating by is why she cleans her face so frantically in this clip. If you’re not sure what this is, it’s a stick-mimicking member of the water bugs and toe biters, the same kind of insect Joe Biden appointed to be in charge of the night time. You can also see some freshwater isopods walk by! This little tank is where I put a lot of pond stuff, so it looks dark and dirty, but it’s probably my most natural and most thriving freshwater enclosure, full of things that love dark and dirty water.

[bogleech]

UPDATE I hope you didn’t watch this and get too attached to the aquatic isopods walking around because she ate them!! (I breed those in multiple tanks anyway)

Barnacle Larvae

Amphibalanus eburneus

When we think of barnacles, we think of the hard, white crustaceans that grow on the side of boats and docks. However, barnacles go through a variety life stages and metamorphosis before they spend their life on a hard surface. The image above is a barnacle larvae when it is in the cypris stage, think of it as a baby barnacle. This larvae is an example of zooplankton and spends a short period of time floating around in the water column.  The second image summarizes the life cycle of a barnacle.

What a delightful world we live in, where little dragons evolve again and again across time, space, and phyla

[vampireapologist-archive-deacti]

my unpopular "cute exotic animal videos" opinion is that even if turns out that the owner is a licensed rehabilitator, rescuer, zookeeper, etc. they still have a responsibility to avoid advertising their animals as attractive pets.

The number of times I see cutsey videos of a lion cub, otter, wolf pup, monkey, etc. playing in someone's living room and people are concerned until, after digging, someone confirm the person making the video runs a rescue or something has started to really bother me.

Yes, public outreach and education is crucial to fundraising for most wildlife causes, but it's possible to engage viewers while making it clear that wild animals do not make appropriate pets (and most people aren't capable keepers!).

If you're a wildlife rehabber sharing videos with no disclaimers etc. of a cute wild animal playing in your kitchen and every third comment is "omg I want one!!! 😍😍😍" chances are you need to rethink your content.

[x-kuntra]

Fucking hate these videos. Wild animals do not want to be your pet, get a dog.

Not to mention videos where a person finds injured/orphaned baby wildlife and decide to raise it themselves, illegally, and then make a “cute” video about how the animal lives with them now because it didn’t want to leave. Yeah no shit because you habituated it you ass hat, you didn’t do that animal any favors. And don’t even get me started about MBD.

These people that think those videos are so damn cute are then encouraged to do the same if they find an orphaned animal. These are the people that “take care of” wildlife without a permit or any knowledge/training on the species and what care it requires, and then finally find a licensed rehabber when the animal stops thriving, when it’s too late. They’re the same people who yell at and shame rehabbers for having to make the compassionate decision to euthanize the animal that THEY FUCKED UP. But still never come to grasp the reality of what they did is actually wrong.

I have some pent up rage over this, clearly. In short, don’t be an ass hat. Don’t encourage this type of behavior, it’s such a huge problem.
