Of all great whales, humpbacks are most prone to breaching. No one knows why. Are they trying to dislodge troublesome parasites or communicating with other whales? Anyone who insures a 15 -metre whale launch itself out of the ocean is sure of one thing: it looks like fun. Melville find of the humpback:” He is the most gamesome and light-hearted of all the whales, making more homosexual foam and white water generally than any other of them .” As this calf leapt, it looked close to landing on a dolphin. Hanging there in the air, a humpback demonstrates its kinship with us. No whale so well deserves its binomial: Megaptera novaeangliae – “big-winged New Englander”, a barnacled angel.
