South of Dondra in Sri Lanka may turn out to t=be the best locations in the world for sighting blue whales. It may also be the best for sighting blue and sperm whales together. This is based on recent observations and a theory of migration of whales by marine biologist Charles Anderson. In April, South of Dondra, had a 100% encounter rate for the highly desired but usually difficult to sight a blue whale.
Talking about blue whales, they are the largest animals ever known to have lived. It is even bigger than the largest dinosaur that lived- the Argentinosaurus. It is estimated that there are around 8000-14000 blue whales, worldwide. The IUCN Red List counts blue whales as endangered. This whale was very quick and powerful for the 19th century whalers to hunt, but with the arrival of harpoon cannons, they became a much sought after species for their large amounts of blubber. The killing spree reached its peak in 1931 when 29,649 blue whales were taken. By 1966, they were so scarce that the International Whaling Commission declared them protected throughout the world.
The blue whale is found in all major oceans of the world. It is found mostly in cold and temperate waters and they prefer deeper oceans as compared to coastal waters. They usually live alone or with one other individual. In locations where there is a high concentration of food, as many as 50 blue whales have been seen scattered over a small area. However, they do not form the close-knit groups as seen in other baleen species.
The longest ever recorded were two females measuring 33.6 and 33.3 meters. These whales are difficult to weigh due to their size. Measurements between 150-170 metric tons were recorded of animals up to 27 meters. The tongue of this whale weighs around 2.7 metric tons and when fully expanded its mouth it large enough to hold up to 90metric tons of food and water. Fascinatingly despite the size of its mouth, the dimensions of its throat are such that it cannot swallow anything bigger than probably a beach ball. Its heart weighs around 600 kilograms the largest known in any animal. Blue whales can reach up to 50 km/hr, an average is about 20km/hr and while feeding 5km/hr.
Blue whales are also the loudest animals on Earth; their call reaches levels up to 188 decibels. This low-frequency whistle can be heard for hundreds of miles. The blue whale is louder than a jet, which reaches 140 decibels. A human shouting is 70 decibels; sounds over 120 decibels are painful to human ears. So when in Sri Lanka, do go on a whaling tour to witness the wonders that Mother Nature beholds for us.
