Diatoms

April 30, 2011

Though the bird count at the Bannerghatta Zoo area was on the low side today (this seemed to be more of an “audio” than a “visual” day, with many more birds being heard than seen!)…we did see a lot of interesting stuff as usual. Here’s one:

Isn’t that really beautiful…and doesn’t it look like the prismatic effect of an oil slick on the puddle? Well…it does, and though it IS an oil slick in a way, it’s far more complex than that.

Diatoms

( click here the Wiki link about them

are a type of phytoplankton, which originated during the Jurassic period. Now, they ooze out on to the rock, and the debris forms a slick upon the water…and that’s what I’ve photopgraphed.

Remember, the sheet rock in and around Bangalore (Peninsular Gneiss) is among the oldest exposed sheet rock in the world, at about 3 billion years….so we were standing on the ancient past, and looking at the light reflecting on something from the Jurassic period…enough to overwhelm anyone into wonder, awe…and silence!
