Octopuses and Coconuts.

Now, for the life of me, I would never dreamed of linking a coconut shell and an Octopus in the same sentence. Maybe I am a poor creative writer or sci-fi writer.

But as is always the case with Nature, here is a bizarre story of Veined Octopuses, which not only use the coconut shells to hide in (see picture above), but actually "walk" around with them. National Geographic has this all covered in an interesting article complete with video. Here.

Random Randomness

Things that I can never stop pondering about - well, there are always too many things. But the one thing that always fascinates me is the true measure of randomness. In short, how random is random?

For all practical purposes, we use calculated randomness - a random generator that has an initial seed. And that is the bias that prevents it from being truly random. It is like approaching infinity. Once you feel you are there, there is always something more. And more. And more. So, how do we actually achieve randomness?

Well, I suppose one way is to not strive for randomness at all. (Gulp! That is not a solution is it?). Well, maybe if we shrunk our perspective to something smaller, then events happening in that purview just might appear to be random. Note the keyword. Appear. Maybe that is all there is to it. True randomness doesn't really matter as much as the appearance of it. So typically human isn't it - the reality does not matter as much as the appearance of reality.

One final word I suppose - lack of bias or randomness maybe is crucial for a lot of our current applications and things, but in the grand cosmic scale of things, maybe everything is truly random and yet really programmed. Yes. Programmed, and random. Together. And yet disparate. Now I am totally confused. Heck. Who cares. Its 07/07/07 07:07:07 PM. Now, I have exactly one year, one month, one day, one hour, one minute and one second to come up with another such random tripe disguised as a blog-post. Boy, the summer heat is really causing my brains to go awry :)

Walking.....Shark??

See related post here.

Ok. So we've seen an octopus that puts up an act. In any of (known till now) three disguises - a lion fish, a flat fish, and a sea-snake the octopus surely puts on a show - evasion? Safety from predators? (Thanks to Tom Tregenza at University of Exeter in Cornwall) Maybe...whatever...ultimately, its just a treat to see an animal mimicking behaviour.

Now we are getting to see another fantastic example of unusual behaviour in another sea-living animal. This time, the walking shark. It apparently walks. See image above (Copyright Conservation International, via AP). Nick-named the epaulette shark, its been observed in the area called Birds Head Seascape off the Indonesian Papua provincial coast in Asia - the so-called Asian Coral Triangle.

Whatever will they find next?
