yeah, we find Giant Squid, we just can't manage to find them alive, which is what makes it so amazing....
There is a thing about the cold cold depths in the ocean near the antarctic. I forget all the readings about it, but the species there have slowly but surely adapted, and in effect, they are are much LARGER than anywhere else in the world. The sad part, is if global warming keeps going, these animals may parish. They slowly have adapted and the water needs only raise a few degrees a year to be too warm for their next generation(s) to adapt.
As for the article... Yeah off of Chile, its just a complete drop off into the depths of the ocean. Sure we have seen the ground with sattalites... but we can't manage to explore everything in the depths. Since there is no light.. its too hard to follow any aniamls... and to top it off... we have light, they don't... so they probly run like hell from the light.... We need a new way to SEE them......
