Three, two, one.

Imagine.

Your blood turns the color of the sky.

And you grow ten legs and a very hard back,

and you have been around for over 400 million years.

You have become a horseshoe crab.

This is Terrestrials, a show where we uncover the strangeness waiting right here on Earth.

I am your host, Lulu Miller, and today we are going to the beach.

I'm bringing you a story all about horseshoe crabs, which are not technically crabs.

They are more closely related to spiders and scorpions than crabs.

But I guess they look pretty crabby, so someone a long time ago misnamed them.

Anyway, it is a very beachy story with waves and birds and fish and even a water slide.

And it initially aired on Radio Lab, our adult show all about the strangeness here on Earth

and science and curiosity, but I think you will love it.

And just a reminder that a whole new season of terrestrials, the new stories, new Allen songs,

yes, is coming in September, September 18th.

So make sure you keep on listening here to the feed.

But for today, as summer winds down, let's take one last trip to the beach.

Helping me tell the story is my good friend and co-host of Radio Lab, Latif Nasser.

Take it away, Latif.

Okay, so three years ago? co-host of Radio Lab, Latif Nasser. Take it away, Latif.

Okay, so three years ago?
