Velvet worms are colorful caterpillar-like creatures that vary
in length from one to eight inches. Closely similar marine fossils have been dated at 500 million years old. The time scale
needs to be challenged; however, the point is that these colorful worms have not changed, evolved, or gone extinct since their
creation. There are about 180 known distinct species of velvet worms.
The rapid oscillating nature of the emitting jets was discovered
only recently with high speed videos. The chaotic motion is called hydrodynamic instability and appears to be unique in the
animal world. Several technical applications are suggested by the ability of this creature. First, the fast-drying glue may
have applications as adhesive ranging from from construction to surgery. The chemistry of the gooey material is not yet understood.
Second, the sprinkler-like spray mechanism may be duplicated in either micro or nanofluid devices. For example, a vibrating
spray nozzle could be part of an ink jet printer, spraying fine particles to print clear individual characters. Third, the
pattern of slime strands fomred by the velvet worm suggests the rapid manufacture of non-woven fiber surfaces.
The lowly velvet
worm has been described as a primitive animal which has evolved a sophisticated ability to protect itself. In truth, this
amazing creature shows highly unusual design. The endless variety of plants and animals displays the Creator’s artwork.
