  • Furthermore, our data suggest that the balance between anterior ERK signaling and posterior b-catenin signaling may vary among planarian species, resulting in the drastic differences of the head-regenerative ability of their tail fragments. (nii.ac.jp)
  • Two planarian species have been used successfully in the Philippines, Indonesia, Hawaii, New Guinea, and Guam to control populations of the imported giant African snail Achatina fulica , which was displacing native snails. (wikipedia.org)
  • worms
  • Planarian worms are cheaper to buy and keep alive than lab rat s. (everything2.com)
  • Keeping this second group and a third control group of planarians (on a normal, non-cannibalistic diet) isolated, they were all trained to run the same maze using the same method as with the first group of worms. (everything2.com)
  • 2) The propensity of planarian worms is to choose to follow a path coated in the mucous or slime trail left by a previous worm rather than to slither off in new directions. (everything2.com)
  • On a tangent to this subject matter, it was also discovered in experimentation that the regenerative abilities of planarian worms didn't just extend to physical organs but memories as well! (everything2.com)
  • If you cut the head off of a trained planarian worm, once it grows back the worm will be able to run mazes as effectively as before, yet if a worm is cut in half (so that each half grows back another half-worm, resulting in two worms) only one of the resultant worms will have retained the training.
