SHARKS and TROPHIC CASCADES

What Happens When Sharks Disappear?
Infographics by Lily Williams

Even worse: Humboldt squid will overpopulate. And they learn what to eat through trial and error. They are even known to attack and seriously harm divers. [x]

Protect your Ocean.

Dragonfly nymphs are voracious predators, hunting everything from mosquito larvae to fish and tadpoles. Their lower jaw is extendable, allowing the nymph to strike with great speed.

I always have fun showing larval odonata to people who don’t know. The adults are jewel-like flitting creatures. The babies are horrible crab aliens with projectile jaws.

Nature is amazing.

A CROW TRIED TO GO IN OUR CLASSROOM AND HE HAD A PEN

You’ve all just like, completely skipped over the possibility that this crow has seen people using pens in this room, found one, and is trying to return it. There’s been videos of crows picking up sweet wrappers and stuff and placing them in bins after seeing humans put their litter in bins. I really do believe that this crow is trying to return the pen and that is ADORABLE AS HELL. 

Another cool crow deal: Once, when trying to assess if crows could reason and use tools, scientists had two crows who didn’t know each other each take a wire from a table (one was hooked, one was straight) and try to grab meat from a bottle with it. The crows could see each other, though they had separate bottles. Only the straight wire worked for this, so they hypothesized that if crows could reason, the second trial would have the two crows fighting over the straight wire. The second trial started and, to the surprise of the scientists, the two crows both went for the bent wire, one held it down and the other unbent it. They both got meat out of their bottles. They came to a peaceful solution without verbal communication. Crows are probably smarter than we are.
