During Memorial Day weekend, Boston aquarium scientists urge beachgoers to report white shark sightings due to observed marine mammal bite marks.

Scientists at a Boston aquarium urge beachgoers to report white shark sightings during Memorial Day weekend in New England, after signs of shark bites were observed on marine mammals. Memorial Day marks the unofficial start of summer, and the region has been experiencing beach weather. Scientists expect white sharks, often referred to as great whites, to head to inshore waters at this time of year to hunt seals.
