The pygmy blue whale (Balaenoptera musculus brevicauda) is a subspecies of the blue whale (Balaenoptera musculus) found in the Indian Ocean and the southern Pacific Ocean.

BLUE WHALE, one of the largest creatures ever known to roam the Earth and yet it dwarfs in size compared to its ancestors. Sadly, researchers have shown that these filter-feeding aquatic creatures only started to binge eat when climate changed. It is an advantage developed due to run-off nutrients from melting ice caps during certain times of the year. 

It is crazy to think their diet really consist of tiny krills, and a day’s worth of them roughly weighs 4 tons. These heavy weight champs themselves weight about 200 tons, that is about 33 elephants! Even though they are at the top of the food chain, heavy whaling before 1966, ship injuries and toxins in the ocean are among the top causes of its’ threatened population on top of climate change. 

I would hope to see their beauty one day and many generations after us too may have the honor. I dream to even just hear their whistle, which is can be heard hundreds of miles away.

The most reliable way to determine the age of a Blue Whale (and other baleen whales to be precise) is by close examination of their earwax. Throughout their lives they form long plugs of earwax of alternating layers of light and dark shades. The changes in colour are caused by the whales dietary pattern of fasting and feasting and each set is produced over one year, therefore, counting the layers gives an indication of the whale’s age. On average, blue whales live between 80 and 90 years.

Scientists have also studied levels of cortisol, the hormone released in times of stress, found in whales’ earwax to determine the impact of human behaviour on the whales. These studies showed that in the 1920s and 30s, when whale hunting was at it’s peak, more cortisol was found in the whales’ earwax, suggesting that the whales had a profound emotional reaction to the hunting. The ear plugs can also be used to determine the pollutants the whales have been exposed to.

Also interesting is the size of a Blue Whale’s heart.

Swedish stamp 2010. Blue whales are found in most oceans except some northern seas. They inhabit Antarctic waters for the abundance of krill.
