A word about oxytocin

the-awkward-turt:

It happens a lot in Reptiblr that someone uses “reptiles don’t produce oxytocin” as evidence that reptiles do not experience social bonding or love.

Here’s the thing though: There are some reptiles that do forge cooperative, long-lasting social bonds and they do so in the absence of oxytocin production.

Something is motivating these animals to protect their young (ex. crocodiles), seek out their siblings to bask with (ex. rattlesnakes), stay with one mate for many years or for life (ex. shingleback skinks), or form family groups and adopt unrelated youngsters (ex. monkey tailed skinks) and it isn’t oxytocin.

Essentially oxytocin is not necessary for the formation of all social bonds in the animal kingdom. In fact birds don’t even produce oxytocin, they produce their own homologous “version” of bonding hormone called mesotocin. And reptiles have an equivalent hormone called arginine-vasotocin that regulates things like egg laying (which is why vets sometimes administer oxytocin to egg-bound reptiles to induce laying).

The argument that most reptiles are not social (or at the very least not cooperative) and experience stress when being cohabbed is totally sound and I am not in any way critiquing that argument. Just wanted to point out that using the “they don’t produce oxytocin” as evidence is a bit mammal-centric and not really definitive proof.

Reptiles, including birds, produce an analogous hormone called mesotocin, and fish have their own version called isotocin.

There’s more in this article linked and quoted below, which I highly recommend reading if you’re at all interested in the topic (the article linked is actually about fish and isotocin):

If there’s any molecule that is consistently viewed through
rose-tinted glasses, it’s oxytocin. This simple hormone has earned
misleading but charmingly alliterative nicknames like “hug hormone”,
“cuddle chemical” and “moral molecule”. Writers love to claim, to the point of absurdity, that oxytocin increases trust, generosity, cooperation and empathy, among a slew of other virtues.

But while these grandiose claims take centre-stage, a lot of careful science plods on in the background.
And it shows that oxytocin affects our social interactions in both
positive and negative ways, depending on the situation we’re in, or our
personality and disposition. It can fuel conformity as well as trust,
envy as well as generosity, and favouritism as well as cooperation. If
we sniff the stuff, we might, for example, become more cooperative towards people we know, but less so towards strangers.

Basically, the long and short of it is that all these hormones do is drive the seeking of social interaction, and are more generalised social substances than positive ones. They can fuel negative and aggressive and hostile interactions as much as positive ones, so they should not be used as evidence of anything other than social behaviour existing.

Golden tortoise beetle transforming from gold to red. Underneath the transparent elytra, or ‘armour’ there are layers upon layers within the cuticle that get thicker and thicker known as a ‘chirped multilayer’. 

These layers are filled with grooves, and when the beetle is undisturbed a fluid fills the grooves of the top layer turning it into a mirror-like surface, giving it a gold appearance. When the beetle is disturbed, the liquid is displaced revealing the true red colour of the beetle on the bottom layers. (Source)

The world’s biggest horse, Brooklyn Supreme, standing 78 inches tall and weighing in at 3,200 pounds.

History In Pictures

Thicc

“Brooklyn Supreme may be 3,200 pounds of solid, magnificent horse flesh, sinew and brawn, but Brooklyn Supreme is a surprisingly gentle fellow whose greatest delight is stealing ice cream cones and goodies from unsuspecting little boys and girls.”

“Yes sir he just love sweets,” his exhibitor Ralph M Fogleman explains. “You watch and see what happens when that kid comes in with that candied apple on a stick. Sure enough, a youngster stood entranced below the towering head and shoulders above him. His candied apple was momentarily forgotten. Brooklyn Supreme calmly reached down, picked it out of his hand, and in a twinkling had separated sweet from stick and stood there smacking his lips.”

I LOVE HIM

How do you tame a horse that big

He was probably raised intently by a human constantly being present, a lot of large breed horses are really intelligent and will learn to let people ride them just by watching people ride the older horses

It’s in part of their blood lines since they’re so large they didn’t have a lot of predators, so they don’t feel threatened by humans

Smaller horses are harder to break because they had lots of human sized predators trying to jump on their backs and claw them apart

Human trying to ride a horse for the first time = horse instinctively thinking something is trying to kill it and will buck it off

Wow! Crazy amazing!

Lake Natron is hot [60 degrees C / 140 F] and extremely alkaline, due to high amounts of the chemical natron (a mix of sodium carbonate and baking soda) in the water. The water’s pH has been measured as high as 10.5—nearly as high as ammonia. The photographer paid locals to collect the calcified birds/animals and posed them for his series “The Calcified” which featured in

The “lizard fish,” or the bathysaurus ferox, is one of the latest deep sea discoveries, pulled out of a fishing net this past summer in Australia. It has a long, eel-like body and a flat head with triangular jaws full of sharp teeth that resemble a lizard, thus the name. The teeth are hinged, and drag any prey in it’s mouth deeper in the more it struggles.

Actual sign in Florida requesting you not give manatees water and raising a lot of questions that it does not answer

hey friends! this just swam across my dash and I wanted to let you all know why you SHOULD NOT give manatees water from your hoses at your docks! See, manatees in the US of A are salt water critters and if they ingest too much fresh water (AKA from the hose as pictured above) it will cause them to get sick and die. Also, it makes them form habits that they will recieve fresh water from these docks, and therefor they’re more likely to be hit by boats in the marina (they cannot hear the frequency that boats produce, therefor they never even see them coming). So for all of you wondering why this is: now you know! Please help keep this gentle giants safe and happy and abide by signs are rules when in areas where manatees roam!
