WATCH: Were Two Endangered Whales Really Caught Hugging?

That’s what the drone video appeared to show.

Wildlife photographer Brian Skerry and scientists from Woods Hole Oceanographic Institution and the New England Aquarium captured this touching moment on February 28th. Two endangered North Atlantic right whales swimming in Cape Cod Bay seemed to embrace one another with their flippers.

The research team says this might be their way of “showing affection and attempts at mating.” This type of interaction is termed “belly to belly.”

North Atlantic right whales are some of the planet’s most endangered animals, with the population estimated at just 360.
