variable length and is a shapeshifter;
- extended length is 2 inches, flat, thin, can be free swimming and in a serpentine motion
-contracted length is 1/2 inches, round, stubby, anchors posterior and moves by extending itself feeling its environment then anchoring the anterior.
-It can also decide to slither if it wants to squeeze in between rocks
