Today is the 16th Annual International Day of the Baltic Sea Harbour Porpoise – a critically endangered sub-population that continues to decline decades after the scientific recognition of its dwindling population size.

Whether it is the Vaquita, the Yangtze finless porpoise or the Baltic Sea Harbour Porpoise, it is clear that these small, intelligent marine mammals cannot withstand the pressures we put on them. They each are considered to be Critically Endangered by the International Union for the Conservation of Nature.
