CNIDARIA Meaning and Definition

  1. Cnidaria refers to a phylum of aquatic animals that includes jellyfish, sea anemones, coral, and hydroids. The term "cnidaria" is derived from the Greek word "cnidos," meaning "stinging nettle," which appropriately describes the characteristic defense mechanism possessed by most members of this phylum.

    Cnidarians are characterized by their radially symmetric bodies, typically having a sac-like shape with a single opening serving as the mouth. They possess specialized cells called cnidocytes, which contain tiny, harpoon-like structures known as nematocysts. These nematocysts are used for prey capture and defense; when triggered, they release venom or toxins that immobilize or kill their target.

    Cnidarians exhibit two main body forms: the medusa and the polyp. The medusa form is bell-shaped and free-floating, while the polyp form is cylindrical and sessile, often attaching to substrates such as coral reefs or rocks. Some cnidarians alternate between these two forms, undergoing a process known as metagenesis or alternation of generations.

    In terms of classification, cnidarians are divided into several classes, including the Scyphozoa (true jellyfish), Anthozoa (sea anemones and corals), Cubozoa (box jellyfish), and Hydrozoa (hydroids and Portuguese man o' war). Cnidarians are found in both marine and freshwater environments across the globe, ranging from shallow coastal waters to the deep sea. They play crucial ecological roles, serving as predators, prey, and habitat builders in marine ecosystems.

    In summary, cnidaria refers to a diverse phylum of aquatic animals characterized by their stinging cells, radially symmetric bodies, and two main
