“Thor Heyerdahl (October 6, 1914, Larvik, Norway – April 18, 2002, Colla Micheri, Italy) was a Norwegian ethnographer and adventurer with a background in zoology and geography. He became notable for his Kon-Tiki expedition, in which he sailed 8,000 km (4,300 miles) by raft from South America to the Tuamotu Islands. All his expeditions are shown in the Kon-Tiki Museum, Oslo”. – Wikipedia

“Snowflake (c. 1964 – November 24, 2003) was an albino gorilla. He was the only known albino gorilla so far, and the most popular resident of the Barcelona Zoo in Catalonia, Spain. Originally named Nfumu Ngui in Fang language ("white gorilla") by his captor, he was then nicknamed Floquet de Neu (Catalan for little snowflake) by his keeper Jordi Sabater Pi. On his arrival to Barcelona where he was given an official reception by the then Mayor of Barcelona, Josep Maria de Porcioles, in November 1966, he was called Blancanieves (“Snow White”) in the newspaper Tele/Exprés. But he became famous with the name given to him by Sabater when National Geographic Magazine featured him on the main page in March 1967, with the English name Snowflake. This name spread among the press (Stern, Life, Paris-Match) and was later translated to Spanish as Copito de Nieve. Sabater himself called the gorilla Floquet or Copi, and in the later years Nfumu. The asteroid 95962 Copito, discovered by Catalan astronomer J. Manteca, is named in his honour”.

The claws are out for North Korean dictator Kim Jong-un and Russia's Vladimir Putin – as cats now able to use a model of him as a scratching post. And moggies can also maul at Russian president Vladimir Putin, whose face also features on the new cat toys which are 1.5ft tall and cost £4,500. They are made from hessian rope, and 3D-printed faces are then attached to the posts, before they are handpainted. The toys took a team of artists 200 hours to finish. (Photo by The Pussycat Riot)

A Sorb egg painter decorates an Easter egg while using bent spoons full of melted wax as coloring at the annual Easter egg market on March 16, 2013 in Schleife, Germany. Easter is a particularly important time of year for Sorbs, a Slavic minority in eastern Germany, and the period includes the tradition of painting Easter eggs that include visual elements intended to ward off evil. Many Sorbs still speak Sorbian, a language closely related to Polish and Czech. (Photo by Adam Berry)
