alien It's been a while since I uploaded as to be honest I think my stream needs a bit of a spring clean so I'm going to try and do that before adding anything new.... got lots of ideas and can't wait to get the boring stuff out the way so I can indulge in a bit of creativity! Wishing everyone a wonderful 2011, hope it gives you all plenty to smile about... :-)
Nautilus Shell. The nautilus inhabit the deep slopes of coral reefs. The shell coloration keeps the animal cryptic in the water. When seen from above, the shell is darker in color and marked with irregular stripes, which helps it blend into the dark water below. The underside is almost completely white, making the animal indistinguishable from brighter waters near the surface. This mode of camouflage is named countershading. --Wikipedia
