participated in watching Humpback Whale migration which happens every year between the months of July and August, in Watamu Marine National Park and Reserve. The whales migrate in search of seas and barriers with warmer temperatures, to favour the reproduction and to give birth. After about 2years of weaning,they then make the return voyage in October, swimming for more than 4.000 KM to the cold seas rich in food of Antarctica, their main feeding area. Watching them in their natural environment, jumping out of the water,in pairs or in larger family groups, is such a memorable experience. This spectacle is comparable to the sight of the great white shark found in other parts of the Indian Ocean coast. Whales are huge animals weighing 30 - 40 tonnes and they are able to jump 2m high and this is not possible for human beings. Just like the big five in terrestrial ecosystem , we also have the big five in marine ecosystem and they include whales, rays, bill fish, dolphins and turtles.
