This postcard (NL-4231932) I sent to Kathrin in Germany (Herford - near Bielefeld).
Postcard details: California Sea Lion (Artis), travelled about 265 km (165 mi) in 42 days
The California Sea Lion is a coastal eared seal native to western North America. It is one of five species of sea lion. Its natural habitat ranges from southeast Alaska to central Mexico, including the Gulf of California. Sea lions are sexually dimorphic, males are larger than females, and have a thicker neck and protruding crest. They mainly haul-out on sandy or rocky beaches, but they also frequent manmade environments such as marinas and wharves. Sea lions feed on a number of species of fish and squid, and are preyed on by killer whales and white sharks.
Artis, short for Natura Artis Magistra (Latin for "Nature is the Teacher of the Arts"), is a Zoo in the centre of Amsterdam.
It's the oldest Zoo in the Netherlands and one of the oldest Zoos of mainland Europe.
Same card I also sent to Sigrun in Germany (Rostock) and travelled about 519 km (322 mi) in 4 days
