Flashcards

Porifera

Animals belonging to the phylum Porifera are characterized by their lack of true tissues and organs. They have a porous body structure that allows for water circulation and filter feeding.

Cnidaria

Organisms belonging to the phylum Cnidaria exhibit radial symmetry and possess specialized stinging cells called cnidocytes. Examples include jellyfish, corals, and sea anemones.

Platyhelminthes

Flatworms, or Platyhelminthes, are bilaterally symmetrical animals with flattened bodies. They lack a true circulatory system and body cavity.

Nematoda

Roundworms, classified as Nematoda, are bilaterally symmetrical and possess a cylindrical body. They have a complete digestive system and are often parasitic.
