NEW SHOREHAM, R.I. (WPRI) — Multiple whales were spotted swimming in Rhode Island waters on Friday.

A 12 News viewer captured video of the whales from their boat off the east side of Block Island.

Biologists from the Rhode Island Department of Environmental Management's Division of Marine Fisheries believe the animals are humpback whales due to their large white pectoral fins.

The DEM says humpback whale sightings are relatively common in the summer, as the whales migrate to colder waters to feed.

According to the department, there have been multiple reports of whale activity around Block Island this spring and summer.
