Tumblr, I’d like to introduce: Stumphrey
He’ll be coming home with us on May 25th. He and Corgnelius will be brothers. And when i say brothers, i mean literally brothers- they came from the same corgi mom and dad :) Pretty soon, it will be double the cuteness and corgi madness. Can’t wait.
Lungs are what enabled the ancestors of all tetrapods to climb out of the Devonian soup some 400 million years ago … Since they utilize the vast surface area of alveoli for gas exchange, rather than the relatively limited amount of surface area provided by a creature’s skin …
- An average human adult’s skin has a surface area of roughly 16-21 square feet
- whereas the surface area of the alveoli inside that same human is about 100 square yards!
Amphibians are neither large, nor particularly active, … amphibians of the order Anura (ie: frogs) evolved four mechanisms for breathing:
- through gills
- via lungs
- through their very permeable skin
- through sensitive skin inside the mouth.
Lungless salamanders (2/3 of all salamander diversity) took things one step further and got rid of the primitive lungs all together, to rely solely on cutaneous gas exchange.

Saw this at Reddit, where the following comment made my day:
“Is that a baby creeper? It’s really short compared to the guy. And considering that it is all in one piece, I assume it hasn’t actually blown itself up and destroyed anything yet.
“So the way I see it, this racist dick just walked up to a little kid and destroyed his sand castle, just because someone who has the same color skin as the kid did something mean to him once upon a time. And now this kid is being taught that everybody hates him for the way he looks. There’s nothing he can do to change their minds. He becomes more bitter and hateful as each day goes by.
“By the time he’s fully grown the anger has been welling up inside him for so long, that the mere sight of some guy building a house just makes him want to explode.”
