Comb jellies belong to which phylum?

Comb jellies belong to which phylum?

• A. Cnidaria
• B. Ctenophora
• C. Chordata
• D. Echinodermata

Answer: (B)

Comb jellies, or Ctenophora, are a distinct group of marine animals known for their gelatinous bodies and unique method of locomotion using rows of cilia. The name "Ctenophora" comes from the Greek words for "comb" (cteno) and "to carry" (phorein), aptly describing their ciliated structures that resemble combs. These organisms exhibit a range of features that set them apart from other phyla, including their lack of stinging cells—which are characteristic of the closely related phylum Cnidaria. Ctenophores are also notable for their bioluminescence and exhibit various fascinating reproductive strategies. Their body structure and developmental processes differentiate them from other phyla such as Chordata, which includes vertebrates, or Echinodermata, which comprises starfish and sea urchins. Thus, the classification of comb jellies under the phylum Ctenophora accurately reflects both their biological characteristics and evolutionary relationships.
