Two massive thresher sharks washed up on Cape Cod Bay beaches this week, a reminder of how the area’s unique geography can trap even the ocean’s most powerful swimmers. As the water chills to near 40°F, sharks try to escape but sometimes get caught in shallow waters and can’t survive. Local experts say these strandings aren’t rare in winter, but it’s always a shock to see such creatures up close. Thresher sharks aren’t a threat to people, but if you spot one stranded, it’s best to call in the pros. What do you think: Should more be done to protect marine life in our bays? #Science #CapeCod #Sharks
