During the carnival season, two turtle nests located on the beaches of Coqueiro and Barro Preto in Luís Correia, Piauí, were reported to have been violated, according to the Instituto Tartarugas do Delta. The nests, which were under surveillance due to their proximity to commercial establishments, were tampered with, although the eggs inside were not harmed. The signs meant to protect the area were removed, indicating a significant disturbance at the site, although the biologist Werlanne Mendes confirmed that there had been no interference with the eggs themselves.

Werlanne Mendes, the vice-president of the turtle conservation institute, reported that the tampering was evident because the markings that indicated the location of the nests were disturbed, with the protective can now being found thrown away in the sand. In light of this incident, technicians from the Secretary of Environment and Water Resources (Semarh) were dispatched to the location in an effort to gather more information, including reviewing surveillance footage from nearby hotels; unfortunately, they were unable to retrieve any useful images.

The violation of turtle nests is classified as an environmental crime in Brazil, highlighting the ongoing challenges in marine wildlife conservation, especially during busy tourist periods like carnival when beach activities peak. This incident underscores the importance of heightened awareness and vigilance regarding wildlife protection, as well as the need for effective measures to safeguard sensitive ecological areas, especially in regions threatened by human activity.
