On a beach in Goa I once observed tiny sand crabs forming perfectly spherical balls out of sand and depositing them around the entrance of their burrows. Observing Nature is not only fun, it inspires and it is said that the Chinese invented paper by copying what wasps did and that flying machines were invented, because humans observed birds and insects. But where did the first wheel-makers get their inspiration from? What could have “got the ball rolling”? Are there any animals or plants that roll or tumble? —>—>
Unusual nests and places: you’d never think of this one!
Nests to shelter eggs, the young of a species and its parent(s) are constructions that are being employed by a wide range of very different animals. Nests may be made entirely from material that is produced by the nest maker alone as, for example, in spiders that spin a cocoon to house their eggs or as in anabantoid labyrinth fishes like the Siamese fighting fish and the South American catfishes of the genus Hoplosternum, which construct nests of air bubbles that these fish spit into a pile that then floats on the surface of the water.
White or pigmentless or both?
I was fascinated as a kid by Hermann Melville’s story about “Moby Dick”, the white sperm whale chased fanatically by Captain Ahab, but who eventually lost the struggle to kill the beast that had dominated his life and caused him never-ending sleepless nights. —>—>
