The background to this research

Everybody loves giraffes, and god knows they've been covered on Tet Zoo enough times (see the links below). And something that's been mentioned many times is the alleged inability of giraffes to swim, or even to float. There are several specific comments on this in the literature (e.g., Shortridge 1934, Goodwin 1954, MacClintock 1973, Wood 1982); Crandall (1964) mentioned a case where a captive giraffe escaped from a carrying crate, fell off the end of a jetty, and immediately sank in the Hudson River (incidentally, dead giraffes have… ]]> Sat, 12 Jun 2010 09:50:00 -0700 http://scienceblogs.com/tetrapodzoology/2010/06/giraffe_flotation_dynamics.php http://seedmagazine.com/content/article/incredible_journeys/ Some animals can instinctively solve navigational problems that have baffled humans for centuries. Now, researchers are uncovering how. The nervous system of the desert ant Cataglyphis fortis, with around 100,000 neurons, is about 1 millionth the size of a human brain. Yet in the featureless deserts of Tunisia, this ant can venture over 100 meters from its nest to find food without becoming lost. Imagine randomly wandering 20 kilometers in the open desert, your tracks obliterated by the wind, then turning around and making a beeline to your starting point—and no GPS allowed! That’s the equivalent of what the desert… ]]> Mon, 01 Mar 2010 10:17:00 -0700 http://seedmagazine.com/content/article/incredible_journeys/
