Contemporary Aboriginal Fibre Art
The Dictyosteliida, cellular slime molds, live individually. When food runs out and they are ready to form sporangia, they release signal molecules into their environment, find each other and create swarms. They join up into a tiny slug-like creature, which crawls to an open place and grows into a fruiting body. Some of the amoebae become spores to begin the next generation, but some of the amoebae sacrifice themselves to become a dead stalk, lifting the spores up into the air.
