pseudocoelomate

Examples of pseudocoelomate in the following topics:

• Animal Characterization Based on Features of Embryological Development

  • Triploblasts can be differentiated into three categories: those that do not develop an internal body cavity called a coelom (acoelomates), those with a true coelom (eucoelomates), and those with "false" coeloms (pseudocoelomates) .
  • The pseudocoelomates have a coelom derived partly from mesoderm and partly from endoderm.
  • The phylum Nematoda (roundworms) is an example of a pseudocoelomate.
  • Triploblasts may be (a) acoelomates, (b) eucoelomates, or (c) pseudocoelomates.
  • Pseudocoelomates also have a body cavity, but it is sandwiched between the endoderm and mesoderm.

• Phylum Nematoda

  • Furthermore, the nematodes, or roundworms, possess a pseudocoelom and have both free-living and parasitic forms.
  • These animals are pseudocoelomates; they have a complete digestive system with a distinct mouth and anus.
  • Nitrogenous wastes may be lost by diffusion through the entire body or into the pseudocoelom (body cavity), where they are removed by specialized cells.

• Nematodes

  • Nematodes, or roundworms, are the most diverse phylum of pseudocoelomates and one of the most diverse animal phyla.

• Phylum Rotifera

  • Rotifers are pseudocoelomates commonly found in fresh water and some salt water environments throughout the world.
