The most characteristic trait of long-finned pilot whales is their large, bulbous, melon-shaped head. Long-finned pilot whales are mostly black with a gray saddle patch behind their dorsal fin and an anchor-shaped mark on their ventral surface. Males can reach up to 8.5 meters, with the average length being 6 meters, and can weigh up to 3,800 kg. Females are smaller, reaching a maximum length of 6 meters, with the average length being 4.8 meters, and can weigh up to 1,800 kg. Initially, calves do not have the bulbous head. The melon grows as the calf matures.
