A mouse can't say whether they see the triangle or not.

So there's lots more to be done before we can make claims about humans.

Okay, Ari, so this new study came out in the journal Scientific Reports, and it's all about how octopuses use different arms for different tasks.

Octopuses have eight arms, and to look at what each arm is doing at a specific point, you have to watch that video eight times.

Just to be clear, octopus researchers have observed some of these arm preferences in lab settings before.

But Kurt Onthank, an octopus researcher at Walla Walla University in Washington State, who's not affiliated with this research, says it's important for us to observe it in the wild, too.

Ari, you are such a great science nerd and you are always welcome on our show.

We're going to miss you.

We'll miss you.

We love having you on for now.

You can hear more of Ari on Consider This and PR's afternoon podcast about what the news means for you.

This episode was produced by Hannah Chen and Jordan Marie Smith.
