Abstract: HIGHLIGHTS • We present the first description of "wealth" inequality in a non-human animal • We describe the distribution of snail shells occupied by a hermit crab species • The distribution of shells resembles the common form of human wealth distributions • Hermit crabs may provide an animal model of the dynamics generating wealth inequality • Shell distribution in hermit crabs provides a baseline to compare to human inequality
