Why do Desert Tortoises release all bodily fluids when they're nervous/scared when Water is scarce in the desert?



Many animals defecate when scared as part of a predator defense mechanism. Often this is especially bad smelling, sticky, forceful, or slippery. You see this is reptiles, amphibians, and mammals. It could easily be due to this, or as part of a relic behavior.

A note on all the conversation about mutations on this page. Mutations do not have to be beneficial to persist, they have to not be harmful. This is a really important point in evolution that's often phrased incorrectly. It's not really, " Survival of the fittests," as it is, "*Death of the least fit*."

It's really more "on average death of the contextually less fit and reproduction of the contextually more fit."
