What is the approximate snout-to-vent length of the Sphaerodactylus parthenopion?

Answer

18 millimeters

The Sphaerodactylus parthenopion, or the Virgin Islands Dwarf Gecko, is one of the smallest known terrestrial vertebrates in the world. Its physical stature is extremely limited, measuring only about one to two inches in total length. When measuring the snout-to-vent length, which is a standard biological measurement for reptiles, this species averages approximately 18 millimeters. This extreme miniaturization is a defining characteristic of the species, placing it in direct competition with the Jaragua dwarf gecko for the title of the smallest terrestrial vertebrate. Such a small body size is fundamental to its biological profile and influences almost every aspect of its survival, from its habitat requirements to its metabolic needs.
