The Guajira Peninsula is one of the most important foraging grounds areas for marine turtles in Venezuela. There, five species converging: the green turtle, hawksbill, loggerhead, leatherback, and olive ridley. The Wayuú indigenous people are inhabits of the Guajira Peninsula. They have a close relationship with these animals, and for generations, they have used these species as subsistence resources. Marine turtle take has always occurred in this area and has historically been high; it is still happening now, but the current extent is unknown. For that reason, we aim to assess and update the estimate for marine turtles take in the Guajira Peninsula. We conducted 25 field surveys between February and March 2022 by visiting 15 locations to seek for alive turtles and remains on landing sites. We recorded the species, date, location of each encounter, and curve carapace length (CCL) measurements. Additionally, 15 semi-structured interviews were conducted with members of the Wayuú community. During field surveys, an estimated 81 marine turtles were identified. The most affected species were green turtles (91.3%, n = 74), followed by hawksbills (3.7%, n = 3), loggerheads (3.7%, n = 3), and leatherbacks (1.2%, n = 1). The majority of green turtles were subadults, with an average CCL size of 64.7 ± 16.5 cm (82.2%, n = 52). Interviewees mentioned that marine turtles were caught for cultural practices, consumption, ancient medicine, and commerce. Further monitoring activities are needed to understand the take level and its implications for marine turtle populations in the Caribbean Basin.
