Cnidaria etymology

Etymology:

The term "Cnidaria" is derived from two Greek words:

  • Knidē (κνίδη): Stinging cell
  • -aria (-αρια): Suffix denoting a group

Meaning:

Cnidaria means "stinging cells," referring to the characteristic stinging cells (cnidocytes) that these organisms use for defense and food capture.

Origin:

The term "Cnidaria" was first coined by the Austrian zoologist Rudolf Leuckart in 1847. He proposed it as a taxonomic group for the invertebrates that possess stinging cells, including jellyfish, sea anemones, and corals. The name was later adopted by other scientists, and it has become the widely accepted scientific term for this phylum of animals.

  • Coelenterates (from Greek "koilos" = hollow and "enteron" = gut)
