DEEP-SEA BOTTOM TRAWLING IS KILLING OUR OCEANS

I ONLY JUST LEARNED ABOUT THE EXISTENCE OF THIS MUSHROOM????? WHICH ERUPTS FROM AN EGG BEFORE UNCURLING HELLISH ARMS, EXPOSING ITS STICKY MASS OF SPORES TO BE SPREAD BY FLIES ATTRACTED BY THE SCENT OF ROTTING FLESH???
Admittedly, I am easily won over by all organisms that attract flies with the scent of rotting flesh. But the octopus stinkhorn (Clathrus archeri) also has tentacles, a freaky egg stage, and blackish goop, so it’s my favorite now.
Killer whales are smart animals. This is what they do in their natural habitat:

Humans might not be the only creatures that care about the welfare of other animals. Scientists are beginning to recognize a pattern in humpback whale behavior around the world, a seemingly intentional effort to rescue animals that are being hunted by killer whales.
Marine ecologist Robert Pitman observed a particularly dramatic example of this behavior back in 2009, while observing a pod of killer whales hunting a Weddell seal trapped on an ice floe off Antarctica. The orcas were able to successfully knock the seal off the ice, and just as they were closing in for the kill, a magnificent humpback whale suddenly rose up out of the water beneath the seal.
This was no mere accident. In order to better protect the seal, the whale placed it safely on its upturned belly to keep it out of the water. As the seal slipped down the whale’s side, the humpback appeared to use its flippers to carefully help the seal back aboard. Finally, when the coast was clear, the seal was able to safely swim off to another, more secure ice floe.

If you’ve ever needed a statistic to slap you in the face to make you give a damn about climate change, this is it: A new report from The Lancet estimates more than 500,000 adults could die in 2050, thanks to how climate change will kill crop productivity, altering the diets and available food all over the world.

The human brain in comparison with those of other animals. The diverse yet unified pattern of nature never fails to amaze me.

A creature that roamed the coasts of the Pacific Northwest about 20 million years ago may have had a feeding style like no other mammal, a new study suggests.
Kolponomos is known only from two bearlike skulls, jawbones, and some toe bones found a few decades ago, so scientists aren’t sure where it fits on the carnivore family tree or even what it really looked like (one artist’s idea is seen above).
Rather than having cheek teeth that could shear meat, as many carnivores do, Kolponomos’s molars were similar to the flattened, low-crowned teeth that otters use to crush their shelled prey—yet the creature lived long before anything similar to modern-day otters evolved.
Now, a new analysis using the same sort of computer software that engineers employ to analyze bridges and aircraft parts suggests that Kolponomos may have collected its shelly prey in a unique way…

Just some lesser known facts about octopuses you guys might like.
Microscopic tardigrades are also called water bears because of their tiny lil bear legs and tiny lil bear-like movements
Mainly interested in ecology, but also the entirety of science.
