Carman V. 2024. Loggerheads Sea Turtles of Argentina. Data downloaded from OBIS-SEAMAP (http://seamap.env.duke.edu/dataset/1907) on yyyy-mm-dd and originated from Satellite Tracking and Analysis Tool (STAT; http://www.seaturtle.org/tracking/index.shtml?project_id=364).



The Argentine Sea is the southernmost distribution of the loggerhead turtle in the West Atlantic Ocean. Along the Argentine coast, their occurrence is evidenced through strandings and incidental captures mainly from late spring to late autumn. The northernmost record occurred in Buenos Aires city (34º 36' S, 58º 26' W) and the southernmost in San Antonio Oeste (40o 37’ S, 64o 55’ W), northern Patagonia. Turtles from 39.5 to 119.0 cm CCL (curved carapace length) are mainly accidentally captured in gillnets and trawlnets in estuarine areas like the Samborombón Bay (34º- 36º S to 55.5º- 57º W).

Little is know about this species in the Southwest Atlantic Ocean. Studying their migratory routes and which places do they usually use for feeding is vital in order to design efficient conservation actions to decrease the turtles that died because of the by catch.


El Mar Argentino es el límite sur de la distribución de la tortuga cabezona en el Atlántico Suroccidental. Es frecuente registrar varamientos y capturas accidentales de esta especie a lo largo de la costa, principalmente desde la primavera hasta principios del otoño. El registro más al norte pertenece a la ciudad de Buenos Aires (34º 36' S, 58º 26' O) y el más al sur a la localidad de San Antonio Oeste (40o 37’ S, 64o 55’ O), en Patagonia norte. Individuos de entre 39.5 y 119.0 cm de largo curvo de caparazón son capturados accidentalmente en redes de enmalle en zonas estuarinas como la Bahía Samborombón (34º- 36º S a 55.5º- 57º O).

Se sabe muy poco acerca de esta especie en el Atlántico Suroccidental. El estudio de sus rutas migratorias y las zonas de alimentación a través del seguimiento satelital de animales es vital a la hora de llevar a cabo acciones de conservación para disminuir la mortalidad debida a la captura accidental.
