Watercolor sketch and notes on one of the smallest whales – the Harbor Porpoise
The Harbor Porpoise
Text and watercolor by Frits Ahlefeldt
This small whale is one of the smallest marine mammals that can be found in oceans especially the northern oceans of the planet, the Harbor Porpoise is about the size of a diver and the females are larger than the males
The Harbor Porpoise can reach an age (seldom) of up to 20 years and they swim alone or in groups of up to five, catching tiny fish and other sea creatures, mostly smaller than a hand.
These tiny whales are even known to swim far up rivers and lakes sometimes.
In most places the Harbor Porpoise is not endangered yet. But both pollution and climate change can unfortunately soon change this situation – also the huge Grey Seal ( 3-4 times larger than the Harbor Porpoise) has in some places started to get a taste for these small whales – and in some areas – especially the Baltic Sea and in the Black Sea the sub populations of the Harbor Porpoise are endangered or critically endangered.
