Abstract Marine debris is dispersed worldwide and has a considerable impact on biodiversity. In this study, the effect of marine debris on the time needed for hatchling loggerheads to reach the ocean once they have emerged from the nest was investigated. After a preliminary census of marine debris on different beaches of Boa Vista Island, Cape Verde, a field test was carried out with four different scenarios: low density marine debris, medium density marine debris, high density marine debris, and a control scenario. The time that hatchlings required to cross the different scenarios was recorded (n = 232). The results showed that crawl times were affected by the different marine debris scenarios, with the "high density" scenario specifically showing a significant difference from the control, low density and medium density scenarios. This study provides information on the risks of marine debris for hatchling sea turtles and provides conservation recommendations to reduce this potential risk. Highlights • The time it takes sea turtle hatchlings to reach the sea after emergence may affect their survival rate. • We investigated how marine debris affects the hatchling crawl along a beach in a field-based experimental design. • Crawl times were affected by the different marine debris scenarios • The presence of marine debris on nesting beaches increases the time that hatchlings need to reach the ocean. • More efforts are needed both at local and international level to decrease the marine debris occurrence in beaches worldwide.
