Difference between cnidaria and ctenophora?
Answers
Answer:
Both cnidarians and ctenophores are diploblastic animals. Cnidarians exhibit radial symmetry whereas ctenophores exhibit biradial symmetry. Both contain tentacles, surrounding their mouth. The main difference between cnidarians and ctenophores is their body symmetry.

Difference Between Cnidaria and Ctenophora
Definition
Cnidaria: Cnidaria refers to a phylum, which contains invertebrate animals with specialized stinging structures in the tentacles that surround the mouth.
Ctenophora: Ctenophora refers to a phylum of coelenterates, which consists of comb jellies.
Symmetry
Cnidaria: Cnidarians exhibit radial symmetry.
Ctenophora: Ctenophores exhibit biradial symmetry.
Diversity
Cnidaria: Cnidarians are highly diversified animals.
Ctenophora: Ctenophores show less diversity.
Habitat
Cnidaria: Cnidarians live in both freshwater and marine habitats.
Ctenophora: Ctenophores live exclusively in marine habitats.
Alteration of Generations
Cnidaria: The Cnidarians show alteration of generations.
Ctenophora: The Ctenophora does not show alteration of generations.
Polyp/Medusa
Cnidaria: Cnidarians possess both polyp and medusa stages.
Ctenophora: Ctenophores only possess the medusa stage.
Sessile/Swimming
Cnidaria: Cnidarians are sessile or free-swimming.
Ctenophora: Ctenophores swim by the comb plates.
Digestive System
Cnidaria: Cnidarians contain an incomplete digestive system.
Ctenophora: Ctenophores contain a complete digestive system.
Unisexual Animals/Hermaphrodites
Cnidaria: Cnidarians can be either unisexual or hermaphrodites.
Ctenophores: Ctenophores are hermaphrodites.
Classes
Cnidaria: The five classes of cnidarians are Anthozoa, Hydrozoa, Cubozoa, Scyphozoa, and Staurozoa.
Ctenophora: The two classes of ctenophores are Tentaculata and Nuda.
Examples
Cnidaria: Jellyfish, corals, Hydra, and sea anemones are cnidarians.
Ctenophora: Comb jellies are the examples of ctenophores.
