What Is the Smartest Creature in the World

What Is the Smartest Creature in the Worldにまつわる役立つ知識を分かりやすく発信ます。

If you want a creature that feels like it dropped in from another planet, meet the octopus. This gooey genius has three hearts, blue blood, and a brain that’s distributed through its arms. Each arm can think for itself while the main brain watches TV.

They can open jars, solve puzzles, and escape tanks like Houdini on espresso. One octopus at an aquarium got so bored it started spraying water at the lights to short-circuit them. That’s not instinct; that’s passive-aggressive engineering.

The Crow: The Tiny Feathered Menace

Now, let’s talk about crows. These birds have the brainpower of a seven-year-old human, but with better anger management. They use tools, recognize human faces, and hold grudges for years.

Scientists have recorded crows dropping nuts in traffic so cars crack them open. Then they wait for the pedestrian walk signal to retrieve the snack. They understand urban planning better than some city council members.

One study showed crows teaching their young which humans are dangerous. That’s right—they have a family gossip network with a permanent hit list.
