Question

Which one of the following locomotion is not characteristic of Hydra?

• A. Looping and somersaulting
• B. Walking
• C. Jet propulsion
• D. Gliding

Answer 1

The correct option is C Jet propulsion

Hydra is generally sessile or sedentary, but they move for hunting. They move by bending over and attaching themselves to the substrate with the help of mouth and the tentacles then release the foot. This process is called as looping. By this process, Hydra can move several inches a day. Walking is also seen in Hydra with the help of foot and hikes. Gliding also occurs as it can slide or glide slowly over the substratum due to creeping.

Therefore, the correct answer is option C.
