The future holds bio-engineering as well as cybernetics. Mix the two and you have a creature that can scan a computer for viruses, spyware, malware, ect. The dragon-like creature has a partial cybernetic brain in it so that it can read and 'enter' the computer itself. Its eyes have a transparent green dome over them to keep out the dust, and if you look closely you might see what it sees, in computer language anyways.

All you need to do is attach the food and waste tube, and then take the plug that sits behind it's horn and plug it into the designated port. All this, for more advance computers such as the super computer the space ships will need, is best done on the perch made for the the scanner dragon within the computer itself. Just remember to take it out once its done. These creatures may be able to live for a while as long as they have feed, but it'll eventually cost you a fortune in that special feed.
