Hydra: Movement and Locomotion

Posted: November 16, 2011 in Uncategorized

If a Hydra is alarmed or attacked, it’s tentacles can be retracted to small buds, and the body column itself can be retracted to a small gelatinous sphere. This happens when a Hydra is exposed to any sort of stimulus like the liver that we put in.This stimulation causes the hydra to take a defensive position and or move around. A Hydra can possibly move around 100 mm. This is an example of Structure and Function. The Hydra’s body and tentacles are structured so that it can move and assume this defensive position
