In August 2021, two juvenile male Antarctic fur seals (Arctocephalus gazella) stranded in the southeastern Brazilian coast and were referred to rehabilitation centers. The animals presented increased body temperature, prostration, respiratory distress and despite treatment died. A necropsy following a standardized protocol was performed, and formalin-fixed tissues were processed for microscopic examination.

Article Synopsis
- Offshore exploration and production of oil and natural gas can lead to contamination of marine organisms through hydrocarbons and metals, which poses a risk to the environment.
- Researchers studied three bird species (two pelagic and one estuarine) to assess their potential as indicators of contamination by various metals and metalloids in an area affected by oil and gas activities.
- Although high levels of some metals were found in the birds, the study suggests that contamination mainly originates from land-based sources rather than direct influence from offshore oil and gas activities, highlighting the importance of seabirds in monitoring environmental health.
The present study reports the first occurrence of (Digenea: Gorgoderidae), in two Olive Ridley Sea turtles (Testudines: Chelonidae), from the states of São Paulo and Sergipe in Brazilian coast. Concerning the Neotropical region, has been previously reported in green sea turtles () from Panama and Brazil, in loggerhead sea turtles () from Brazil, in hawksbill sea turtles () from Puerto Rico, and in Olive Ridley Sea turtles only in Costa Rica. Lesions resulting from the presence of parasites in the hosts' urinary bladders are also presented.
