A week and half ago multiple science news outlets reported on the publication of a study that described a new species of Geckolepis geckos, a bizarre genus that goes by the more common moniker of “fish-scale” geckos. They appear to be relatively unique to the Comoros Islands and Madagascar, locations that harbor other fascinating endemic species (restricted to a certain region), a fact which can largely be attributed to island isolation.

These lizards are sheathed in a layer of vibrant scales that they jettison quickly in response to perceived predatory threats. Mark Scherz, the PhD candidate who lead-authors the study, experienced significant challenges trying to collect fully-covered specimens of what would later be identified as Geckolepis megalepis. The gecko loses skin with scales, and much resembles a naked baby mouse after the process. As the study notes, “The new species has the largest known body scales of any gecko (both relatively and absolutely), which come off with exceptional ease.”

This quality of Genus Geckolepis to lose then regenerate scales is suggested to have applications in human medicine with regards to tissue recovery. In addition, geckos have been studied for other enviable qualities including their ability to adhere to vertical surfaces with ease.
