Humpback whales typically migrate up to 25,000 km (16,000 mi) each year. They feed in polar waters, and migrate to tropical or subtropical waters to breed and give birth, fasting and living off their fat reserves. Their diet consists mostly of krill and small fish.
Humpback whale (Megaptera novaeangliae) is a species of baleen whale. Adults range in length from 12–16 m (39–52 ft) and weigh around 25–30 metric tons. The humpback has a distinctive body shape, with long pectoral fins and a knobbly head.

After breeding season, moulting occurs, where King Penguins lose their old feathers and have them replaced by new ones. Like the juveniles, adults cannot fish for food until they have a new fully intact and functioning set of feathers, so this moult period is one of starvation while living on food reserves.
In this picture the king penguins are moulting along the river edge to regulate the temperature of their bodies. By leaving their feet in the glacier stream it stabilizes their core body temperature of 38°C (100.4°F).
