Reptiles exhibit a wide diversity of social systems, and while not very common, exclusive and consensual mating relationships have been documented in several lizard species including lizards from the Teiidae family. Here, we document dyadic movement behavior between an adult male and female Salvator merianae (Argentine Black and White Tegu), a large, omnivorous lizard native to Brazil, Uruguay, eastern Paraguay, and Argentina that became established as an invasive species in Florida, in the southeastern United States. Using global positioning system and very high frequency telemetry data, we documented 8–9 days of joint movement between a reproductively active male and female Tegu in Miami-Dade County, FL.
