Taxonomic Etymology:
Named for its comb-like tail spines.
Ctenosaura — From Greek ktenos (κτενός), “comb,” and saura (σαύρα), “lizard.” The name means “comb lizard,” referring to the comb-like crest of enlarged spines running along the back and tail.
pectinata — From Latin pecten, “comb,” and the suffix -ata, meaning “provided with.” Refers to the comb-like, pectinate tail spines that are characteristic of the genus and particularly well-developed in this species.
