Links: Composting Plastics, Venomous Octopuses, and Serenading Sharks.

Here's another link post, so you don't have to read my silly writings!


Our first link is about biodegradable plastics, the development of which has been going on for several years and there have been some results. These "plastics" are actually made from plant material, such as corn starch or tree-produced sugars, and degrade in a compost environment in 6 months time. I wonder when we'll be seeing these plastics in our grocer.

Compostable Plastics have a Sweet Ending @ ScienceDaily.com

Second is a quite silly continuation of our Ode to Discovery's Shark Week, a man serenading Great White Sharks. He was actually in the water with the sharks and guitar, but I'm guessing they dubbed over the music :).

Seriously, the video's pretty funny.


And our final link also takes place in the ocean, but deals with something with a little less of a backbone. It wasn't until recently that scientists discovered that all octopi, not just the Blue-ringed Octopus, are actually venomous. A study into Antarctic octopi discovered four new species of octopus and two completely new toxins that these octopus carry.

Iiiiiiit's SHARK WEEK!


I lieu of Discovery Channel's Shark Week (which I look forward to every year), I give you the ridiculous looking "Goblin Shark" (Scientific name: Mitsukurina owstoni). It was named such because of the front of the shark, which looks much like a goblin's nose. That snout, called a rostrum, isn't just for show! It contains electro-sensitive organs that help it sense when other living things are nearby. It was first discovered in 1897 by a Japanese fisherman and, although many specimens have been recovered since then, there is still relatively little known about the shark. What is known is that it's a deep-water shark that rarely enters shallow water and is widely distributed. It's generally seen when caught accidentally by deep-sea fisherman or trollers, but this minimal harvest doesn't appear to be harmful to their population. Seriously, though, check out this video showing how the goblin shark attacks prey (or this man's arm).
