In warm summer months, many people travel across continents in mobile homes (a.k.a. campers or caravans), so they can visit new places and outdoor spaces with the convenience of always having their familiar nightly shelter nearby.

In nature, many critters just grow their own homes and carry them along. Not just turtles, but also snails and myriad species of shellfish carry their supportive structure on the outside.

So where are the animals in all those shells we see on the beach?
