CBSE Class 9 Answered
Why are Coelentrates also called Cnidaria?
Asked by | 30 Jun, 2008, 10:46: AM
Expert Answer
Coelenterates show the presence of specialised cells called cnidoblasts, which bear stinging structures called nematocysts. These help in capturing the prey by paralysing them with the injected toxin. Due to the presence of cnidoblasts, they are also called cnidarians.
'C' is silent. It is pronounced as 'nidaria'.
