How do ctenophores move?
Options
- AThrough the use of tentacle
- BThrough the use of ciliated comb plates
- CThrough the use of fins
- DThrough the use of a tail
Correct answer
B. Through the use of ciliated comb plates
Step-by-step solution
Ctenophores are exclusively marine organisms that have radially symmetrical body structure. Ctenophores have eight external rows of ciliated comb plates which help them in locomotion .Digestion is both extracellular and intracellular. Bioluminescence (the property of a living organism to emit light) is well-marked in ctenophores. Sexes are not separate. Reproduction takes place only by sexual means. Fertilisation is external with indirect development.
