Right Whale Sighting (image) Woods Hole Oceanographic Institution Caption Right whale experts from the New England Aquarium, which maintains a catalog of all known North Atlantic right whales, joined the WHOI team onboard RV Endeavor. During the expedition, they identified four individual right whales, including #3611, seen here, an unnamed male. To identify the animals, the experts examine unique features on the whales, such as scars, patterns of color, and the patches of thickened skin on their heads, called callosities.
