  • Hi, I am Jared, and welcome a Fun Science Demos. Here on location in the sunny, sandy

  • beaches of Delaware.

  • The big idea today is horseshoe crabs.

  • What are they doing? They are all gathered together along

  • the whole shore of these beaches. What are they all doing?

  • They are laying eggs and that is the cool part,

  • it is the story have a horseshoe crab. Right now they are laying eggs but a

  • bigger part of that story is,

  • they have already laid eggs further up the beach. Let us go see if we can find some

  • of those eggs.

  • To find the horseshoe crab eggs, we have to go

  • under the sand. The horseshoe crab will bury herself under the sand and lay her

  • eggs, so we have got to start digging.

  • And I happen to have some hands. What I am doing, is I am

  • digging very gently and I am looking for. clumps of green eggs.

  • Ahhh!

  • I found a tiny clump. Each horseshoe crab

  • lays hundreds of eggs just like this,

  • and each one of these eggs will hatch into a baby horseshoe crab

  • about six to eight weeks from now. So to go from these eggs

  • to this horseshoe crab takes about nine years

  • for them to reach an adulthood. Think about that:

  • nine-years-old. It is the cycle of life,

  • from eggs to adults. If you want to learn more about horseshoe crabs

  • and their green eggs in the sand, check out our links in the video description.

  • Science is so cool. Thanks for watching. Go back home big guy!
