For hermit crabs, a suitable shell is one of the most essential elements of their survival. Why? Because their shells are their greatest defense mechanism. It of course provides them with a source of armor against potential predators, but that’s not all.
Their shells also shield them from the elements. Without them, these little guys would quickly bake under the hot sun, particularly in tropical climates.

And even then, the process of finding a suitable home doesn’t start and stop with the individual’s needs. Instead, they have to be patient.

And that’s when the real-estate transactions begin!
In the video below, you’ll see how a group of hermit crabs execute a near-perfect exchange of homes. It’s by far one of the most bizarre rituals I’ve ever seen! Check it out!Whizzco
