animalworld: BLUE BELL TUNICATE COLONYClavelina moluccensis©Nick Hobgood While they look like vacuum cleaner hoses, they are actually tunicates or sea squirts and not man-made trash. Bluebell tunicate, blue bell tunicate, or Blue Sea Squirt, is a species of tunicate (sea squirt), in the genus Clavelina (the “little bottles”). Like all ascidians, these sessile animals are filter feeders. This species is 0.5-2.5 cm long, and light to medium blue in colour. The top of the zooids contain characteristic dark blue patches and spots that are always visible This species is found in the waters around Australia, Western Pacific, Indonesia, Papua New Guinea, Mariana Islands, Philippines, Singapore, and Malaysia. This species grows in clusters attached to dead coral or other hard substrates, normally under overhangs.  Tunicate blood is particularly interesting. It contains high concentrations of the transition metal vanadium and vanadium-associated proteins as well as higher than usual levels of lithium. Some tunicates can concentrate vanadium up to a level one million times that of the surrounding seawater. Specialized cells can concentrate heavy metals, which are then deposited in the tunic.

Deft manipulation of perspective gives viewers a detailed look inside the human circulatory system. 

The relationship between a tiny oxygen atom and the giant organ of the heart was accomplished with a common painting technique that fits many scales into a single picture, according to Jennifer Frazier of San Francisco’s Exploratorium. 

The unusual view won artist Linda Nye first place in the illustration category of the 2008 International Science and Engineering Visualization Challenge.
