In Fiordland, runoff from the unusually high rainfall creates a permanent tannin stained fresh water layer ranging in depth between 5cm and 10m on top of the salt water.
This dark fresh water layer prevents light from penetrating the ocean and as a consequence many marine species which are usually restricted to deep water (depth larger than 100 meters) flourish in shallow water (depths of less than 50 meters).
This allows recreational divers to observe species that normally live beyond their recreational dive depth range.
The Addo Elephant Park’s flightless dung beetle (Circellium bacchus) has no wings, but uses the sealed wing case as a CO2 store to exhale less frequently and thus minimize moisture loss during breathing.
This allows the beetle to survive the arid conditions prevalent in that part of the Eastern Cape.
And yes, in Addo dung beetles have right of way.
Stillsuit is a moisture saving suit from the book Dune (by Frank Herbert).
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.
They have a normal upper lid that closes downwards when the owl blinks, a lower lid that closes upwards when the owl is asleep and a third translucent eyelid that closes diagonally across the eye to moisten and protect it while maintaining vision.
This third eyelid is called a nictitating membrane and can be seen in the left hand side eye of this Spotted Eagle Owl.
