The southern humpback whales, which begin to be seen from August to October , come from as far away as Antarctica, we are talking about one of the longest migrations of animals on the planet. In the tropics, these humpback whales do not eat, and survive completely from the fat reserves they have accumulated. Humpback whales grow up to 17 meters long and can weigh up to 43,500 kg. They are found in the oceans throughout the world, and spend half of the year feeding on cold, nutrient-rich waters, then migrating to warm, tropical waters to mate with the humpback whales of the northern and southern hemispheres. The humpbacks of the north, who visit us between January and March, come from as far away as California.
