The demise of Vine is drawing closer. I couldn’t stand the thought of all those cat videos out there being lost to the abyss, so I gathered a few (i.e. nearly 50) of my favourites.

I hope you enjoy this compilation of cats and kittens being funny, silly, or just plain adorable.

Pros: some very cute videos, and only 3 of irresponsible behavior.

Cons:2 of those videos are of, respectively, a young lion and a young cheetah in people’s houses.

Those things growing out of this giant Australian cuttlefish (Sepia apama) are its skin papillae. It can extend and retract its papillae at will, helping it alter its texture to better blend in with its surroundings.

Both papillae expression and color change are controlled by visual, not tactile, cues. This means that these guys don’t need to actually touch anything to decide on their camouflage strategy.

Just by looking, they are clever enough to decide what sort of color, pattern, and texture is needed to virtually disappear.

Did blind cavefish evolve by breaking the laws of evolution?

mindblowingscience:

We’ve found out why a Mexican cavefish has no eyes – and the surprising answer is likely to be seized upon by those who think the standard view of evolution needs revising.

Over the past few million years, blind forms of the Mexican tetra (Astyanax mexicanus) have evolved in caves. Maintaining eyes and the visual parts of the brain uses lots of energy, so the loss of eyes is a big advantage for animals living in the dark. Instead the cavefish “see” by sucking.

It was assumed that these fish became blind because mutations disabled key genes involved in eye development. This has been shown to be the case for some other underground species that have lost their eyes.

But Aniket Gore of the US’s National Institute of Child Health and Human Development and colleagues haven’t found any disabling changes in the DNA sequences of eye development genes in the cavefish.

Watch this barber slug fulfill its anemoneeds!

🎥Joe Platko in Monterey!

UPDATE! Hey everyone! Sorry for the confusion! Here’s more info to explain what’s going on: The anemone retreats once it feels the pinch of the barber slug’s bite. Latching on, the slug is pulled in with the anemone, not wanting to let go of its meal. Once the slug snips off a tentacle or two, it pulls itself back out of the tube and moves on to the next anemone spaghetti dish, while the anemone waits for the coast to clear before coming back out from its tube.

Yikes!
