IndiaA recent scientific study has challenged the long-held belief that Greenland sharks are blind due to age-related eye damage caused by parasites. While it is well-established that these sharks can live for nearly 400 years, based on radiocarbon dating of their eye lenses, a separate claim about their vision has been called into question. Earlier research suggested that the presence of a common parasite, Ommatokoita elongata, might have impaired their sight, leading to widespread assumptions that the sharks were effectively blind. However, new research published in Nature indicates that Greenland sharks maintain a functional visual system adapted to low-light environments, contradicting earlier speculation. This finding highlights the importance of direct testing in understanding animal biology, especially for species that are difficult to observe in their natural habitat.
