Hiding In Plain Sight
Cephalopods, such as the octopus shown here, have incredible powers of camouflage.
While most animals maintain an unchanging body pattern and coloration (think a praying mantis on a leaf), or a slow-transition color-change ability (think chameleons), cephalopods exhibit what is called “adaptive camouflage”.
This is the ability to quickly alter their coloration, body pattern, and even texture to best blend in with their surroundings.
If detected, these guys can jet away in a cloud of ink as a last resort.

The Old Ones Remember
In addition to their unparalleled powers of camouflage, octopuses are equipped with incredible powers of the mind.
Octopuses have evolved a brain and central nervous system comparable to that of vertebrates, endowing these creatures with the ability to learn through observation, and form long-term memories of their experiences.
The remarkable mental faculties of octopuses, the most advanced among all invertebrates, has made them ideal subjects for research on neurobiology. Scientists continue to
call upon the knowledge of the Old Onesstudy these amazing cephalopods to discover more about the processes of learning and memory.

A deep sea octopus making shapes.
Octopods like this have long, fleshy spikes known as cirri lining their arms. It’s thought they’re used to create a current which draws copepods to the mouth.
There are a whole bunch of deep sea octopods with mantle fins and cirri, all belonging to a suborder called cirrata. Few are as colourful as this one, though!

NOW I CAN BE A TRUE MERMAID
I actually did a report on this last year! The substance is called perfluorocarbon and because of its unique nature, it can hold enough oxygen inside of it for you to breathe it. You can breathe safely while inside it, but sometimes the transition from breathing in the perfluorocarbon and the air can be painful or uncomfortable as your lungs try to push the liquid out of them. In Dan Brown’s book The Lost Symbol, the process of reverting back to breathing the air can feel like being birthed.
thank you friend
how the fuck do they know what being birthed feels like
This liquid is used in modern torture. It is similar to water boarding. A victim is placed in a small completely dark box. The box is then filled with the liquid. The victim thinks they are drowning as they breath the liquid in. Most pass out from fear at this point or they just sit there in the liquid in pitch black, apparently breathing ‘water’. Often it leads to the thought that they are in fact dead. It is completely terrifying. Then the box is opened and they are violently pulled from it. As said before the transition from liquid to air is none too pleasant. You might be told something like, they resuscitated you and to tell them what you know or they will “drown” you again.
You can “drown” someone and be sure that they won’t be harmed
You all needed to know this.
what the fuck to both of those
What happens to cats in zero gravity ? more educational gifs«
OH GOD THOSE POOR BABIES i am sobbing i am laughing so hard
In the last pic the cat is all “oh thank god I found ground NO WAIT COME BACK GROUND”
THOSE POOR BABIES OMG WHY AM I LAUGHING AT THIS
Is that… is that even healthy?
There are sea organisms and fungi which glow in the dark and there’s fireflies and jellyfish which glow in the dark. It doesn’t do them any harm nor does it do the people around them any harm. I would say its pretty healthy, as well as it would mean more photosynthesis happening in cities which mean cleaner air.
I was just curious about how they were doing it and for some reason I didn’t think to click the link. But thanks! It makes more sense now. I was afraid it was some kind of chemical thing.
nah just genetic modification using existing bioluminescent genes. Genetics is really cool, and so is bioluminescence. I mean they’ve already made pigs glow using jellyfish genes and pigs are waaay more complicated than trees iirc. So they’re actually (i think) less likely to muck it up with trees.
In which case
(I like glowy things)
That’s pretty dope.
WHY SO SERIOUS: WARNER BROS. REPORTEDLY ORDERS ‘NO JOKES’ IN NEW DC COMICS MOVIES
Comics fans have become well acquainted with the notion that sometimes, creative people learn the wrong things from successes. It’s why certain comics have been dominated for going on 30 years by a “dark” and “mature” sensibility that often comes off as grim, self-serious and overcooked.
Well, get ready for that way of thinking to make its way to movie theaters very soon. According to a report at Hitfix, Warner Bros. has a strict rule for its upcoming DC Comics movies: “No jokes.”
What’s particularly surprising is that the rule — which itself is kind of a joke, when you think about it — is that it stems from a failure more than it does a success, at least, according to Hitfix writer Drew McWeeny’s thinking.
So is anyone else ready to watch the joy and fun be sucked out of their favorite characters on the big screen? Or do you like the initiative WB is taking because frivolity is for babies?
I guess you can see my position from reading the question.
