Question

Select the correct one(s) for Ctenophora -

• A. They have similarities with Cnidaria
• B. They have 8 external rows of ciliated comb plates for locomotion
• C. Bioluminescene
• D. All

Answer 1

The correct option is D All

Ctenophores, variously known as comb jellies, sea gooseberries, sea walnuts, or Venus's girdles, are voracious predators. Unlike cnidarians, with which they share several superficial similarities, they lack stinging cells. They have ciliated comb plates for locomotion and exhibit bioluminescence

So, the correct option is 'All'
