Hammerhead shark sightings are less common than great white shark sightings off Cape Cod, but this isn't the first time they've been spotted here. According to The Boston Globe, a hammerhead was sighted at a Nantucket beach back in 2022.
Hammerhead sharks are actually a group of 10 different sharks known for the unusual and distinctive form of their heads. They range in size from about 3-20 feet and can weigh up to 1,500 lbs.
