A grey seal pup and its mother are seen at Donna Nook National Nature Reserve on November 16, 2025, in Louth, England. In 2024, the reserve recorded a 25% drop in seal pup numbers compared with the previous year – the largest decline since monitoring began 40 years earlier, according to the Lincolnshire Wildlife Trust. Early indications suggest numbers are recovering this season, with 942 pups born so far. (Photo by Brook Mitchell/Getty Images)
