What type of digestion do ctenophores have?

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. Ctenophores have both intracellular and extracellular digestion. 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.
