Many-headed Slime

Physarum polycephalum


This enigmatic slime mold moves using shuttle streaming, which is characterized by rhythmic back-and-forth flow of the protoplasm. Incredibly, this slime mold exhibits intelligent characteristics similar to those seen in single-celled creatures and social insects. For example, it is able to solve the shortest path problem - When grown in a maze, P. polycephalum will retract from everywhere in the maze, except the shortest route connecting the food sources, thus producing efficient networks by getting to the food using the shortest route. Amazing!


Habitat: Growing under bark on a fallen, rotting tree in a deciduous forest.

Thanks so much for the nomination! @Maria dB - yes! They are so freaky and awesome. There are some crazy slime lapse videos of them on youtube, which show them in motion :D

That is fascinating - the stuff of a sci fi or horror movie. :)

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!
