Colophon

The animal on the cover of Getting Started with Fluidinfo is a jellyfish-like animal of the genus Stephalia. The genus encompasses three species (S. bathyphysa, S. corona, and S. dilata).

These creatures belong to the order Siphonophora, a group of marine invertebrates noted for its strange and striking members. Though they appear to be a single animal (like true jellyfish), siphonophores are actually colonies of intertwined specialized zooids. Some members of the order grow to enormous lengths (the giant siphonophore may be 40 to 50 meters long), others have severely venomous stings (such as the Portuguese man-of-war), and still others are able to produce light (which they use to attract their prey).
