A possible large shark has been recorded in waters near Nazaré, Portugal, prompting public concern. Video footage shows what appears to be a shark swimming near the coastline in the Nazaré area, which is well known for attracting surfers because of its exceptionally large, record-breaking waves. The shark’s size is described as around 10 to 13 feet, with some reports suggesting it could be a great white shark, while others describe it more generally as a possible great white due to the difficulty of confirming species from footage alone. The reports indicate the footage was captured off Nazaré and circulated with estimates based on visible dimensions in the video. No official determination of the animal’s species or exact length is included in the provided accounts, and there are no confirmed details about the shark’s health, behavior beyond swimming, or any immediate actions taken by authorities. The sightings raise questions about the presence of large predatory fish in coastal waters used for recreation and tourism, but the information available so far is limited to the video and size estimates.
