Police in Scarborough, Maine are warning people about a great white shark that was spotted multiple times this week lurking near the coastline.

White sharks, made famous 50 years ago in the movie “Jaws,” are not commonly seen off Maine, but have lived in the state’s waters for centuries. Sightings ticked up in recent years, and some scientists say the state’s growing population of seals could be a reason for more shark activity. White sharks feed on marine mammals such as seals.
