Be you an armadillo or not, others may or may not perceive you to be unique. The how and why of that gets a vigorous (and possibly unique) writeup in this study:
“What Makes Each of Us Unique? The Nine-Banded Armadillo as a Model to Study Individuality,” Delva P. Leao, Alvaro Duque, and Marcelo O. Dietrich, Frontiers in Mammal Science, vol. 3, 2024, article 1450655. The authors explain:
“Here, we argue that the nine-banded armadillo is a unique organism for the study of how inter-individual differences are expressed in the mammalian brain. Our argument is based on the fascinating reproductive biology of armadillos, the only known mammals that always generate offspring that are genetic clones, and on how this characteristic can help understand the complex interplay between genetic, environmental, and stochastic factors in the biology of individuality. We will first review the sources of variance in brain-related traits and behavior, then the biology of armadillos, and finally how they can aid in understanding the origins of variance in brain structure and function.”
