Dive into the fascinating world of critters with "Stuff You Should Know" as hosts Josh Clark and Chuck Bryant explore the peculiar life of a creature you might not think twice about: the roly-poly. This unassuming terrestrial crustacean, known by a plethora of names across regions, might surprise you with its unique biology and significant role in our ecosystem. Find out why these creatures are more than just charming garden dwellers and understand the basics of their anatomy that sets them apart from insects.
From Josh and Chuck's lively discussion, learn about the roly-poly's distinctive adaptations that aid in their survival—from their ability to curl into a protective ball to the curious process of coprophagy for nutrient intake. Moreover, the episode delves into their critical environmental contributions as composters improving soil quality. By the end of this engaging chat, you'll discover how the roly-poly not only enriches the dirt underneath our feet but also serves as a natural agent in bioremediation by safely processing heavy metals in contaminated soils.

Roly-polies, also known as pill bugs or potato bugs, are unique terrestrial crustaceans. Unlike insects, they breathe through gills and are the only crustaceans adapted to live entirely on land. They have garnered various regional names such as wood lice, cheeky pigs, penny sows, and cheesy bugs, but are most commonly called roly-polies, especially in the American South.
Roly-polies have developed several key adaptations for survival. They can curl into balls for protection and to maintain moisture in their gills, which is vital for their breathing. They re-consume their own feces in a process called coprophagy to maximize nutrient absorption. Remarkably, they can also absorb water through both their mouth and a rear appendage. Female roly-polies carry and protect their eggs in a special pouch called a marsupium, where the offspring can return for shelter even after hatching.
As described by Chuck Bryant and Josh Clark, roly-polies are ecosystem engineers, aiding in composting and soil health. These creatures consume decaying matter and excrete it, enriching the soil with nutrients. In gardens, they play a constructive role by improving soil quality rather than harming plants. Furthermore, they possess the unique ability to ingest heavy metals from contaminated soil and crystallize these metals in their guts, providing a form of bioremediation and reducing environmental hazards.
1-Page Summary
Roly-polies, commonly referred to as pill bugs or potato bugs, are fascinating creatures that defy common misconceptions about crustaceans.
Surprisingly, roly-polies are not insects. They are, in fact, crustaceans and have the unique distinction of being the only crustaceans that are fully terrestrial, breathing through gills.

Roly-poly basics
...
Roly-polies, otherwise known as pill bugs, have developed unique adaptations that contribute significantly to their survival.
An essential adaptation of roly-polies is their ability to "conglobate," or curl up into a tight ball. This behavior serves as an evolutionary response to potential threats from predators. Beyond defense, conglobation also helps roly-polies maintain moisture in their gills, which is crucial as they breathe through gills that must stay moist to function properly.
The article does not provide details on this point, but it is well-known that some species of roly-polies eat their own feces—a process known as coprophagy. This behavior enables them to extract the maximum amount of nutrients from their food due to the microbial action that takes place in their manure.
A unique physiological trait of these creatures is their ability to drink from both their mouth and a tube-like structure locat ...

A discussion with Chuck Bryant and Josh Clark reveals the beneficial environmental roles of roly-polies, including composting and soil remediation.
Chuck Bryant describes roly-polies as detritivorous creatures that feed on decomposing plant matter, dead animals, and other feces. These little crustaceans digest this matter and excrete it, thus acting like small composting machines that help break down dead material and add nutrients back into the soil.
Roly-polies are not only harmless to garden plants but are also beneficial, according to Josh Clark. These creatures contribute positively to gardens by helping the garden grow even better, not by directly feeding on the plants but by breaking down organic matter and improving soil health.
Roly-polies also have a remarkable ability to clean up con ...
