Solution
The structure that hydra uses to immobilize its prey is called
A
Enteron
B
Osteoblasts
C
Osteocysts
D
nematocysts
E
Pneumatophores.
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Hydras use nematocysts, which are stinging cells, to immobilize their prey. These cells, found on the tentacles, contain coiled, barbed threads that inject a toxin upon contact with a potential prey. The toxin paralyzes or kills the prey, making it easier for the hydra to capture and digest it.
