How does Hydra catch its prey?
Asked by Topperlearning User | 04 Jun, 2014, 01:23: PM
Expert Answer
Hydra extends its tentacles to the largest extent. As soon as any possible victim touches its tentacles, it is pierced by fine poisonous threads shot out by the stinging cells (nematocysts) located on the tentacles. The paralyzed prey is held by the threads and is slowly pushed into the mouth by the combined effort of contracting tentacles.
