Fishing spiders (genus Dolomedes) do not spin webs to catch pray. Instead they hunt by anchoring themselves to shore with their hind legs and extending their front legs onto the water surface to detect movement much like other spiders use webs. When they detect the ripples from prey, they run across the surface to subdue it using their foremost legs, which are tipped with small claws.
They are able to travel on water because they are covered all over in short, velvety hairs which are unwettable (hydrophobic).
They are also more than capable of going underwater. The hairs on the abdomen trap air, allowing it to carry its own air supply when it submerges.
The nursery web spider (Dolomedes minor) do not restrict themselves to stay close to open water but are capable fisherman none the less.
Why do the Afrikaans speaking people refer to a grey rhinoceros as white? The popular etymological story goes like this:
The Dutch at the Cape of Good Hope called the white rhinoceros the “wide” (Dutch: wijd, Afrikaans: wyd) rhinoceros to refer to its wide mouth adapted for grazing – a grass eater. Its mouth is an anatomical feature that distinguishes it from the black rhinoceros, which is a browser – a leaf eater.
The English misheard/mistranslated ‘wijd’ and started calling the rhino “white”.
Some years later, the Dutch/Afrikaners on hearing that the English refer to this rhino as white, decided to use the Afrikaans translation for white rather than stick with the anatomically correct name they purportedly gave it earlier.
You won’t be alone in your incredulity; Kees Rookmaaker, Chief Editor of the Rhino Resource Center wrote in a 2003 publication “the popular explanation that ‘white’ is derived from the Afrikaans word ‘wyd’ is examined and found to be unsubstantiated and historically incorrect.”
Did you know, during their lifetime, elephants have six successive sets of molars? A new set develops in the back of the jaw and moves forward to replace an older set that has worn away grinding down the vegetation they eat.
