Study Notes
###Â Animal Kingdom Classification
- Porifera are multicellular animals with cellular level of organization and flagellated choanocytes.
- Coelenterata have tentacles and cnidoblasts.
- Sponges are mostly asymmetrical.
- Radial Symmetry exists in organisms where any plane passing through the central axis divides the organism into two identical halves.
- Bilateral Symmetry exists in organisms where the body can be divided into identical left and right halves in only one plane.
- Diploblastic Animals have cells arranged in two embryonic layers: an external ectoderm and an internal endoderm.
- Triploblastic Animals have a third germinal layer, mesoderm, between the ectoderm and endoderm.
- Coelom is a body cavity lined by mesoderm.
- Cnidarians have a skeleton composed of calcium carbonate.
- Cnidarians exhibit two basic body forms: polyp and medusa.
- Polyp is a sessile and cylindrical form, like Hydra.
- Medusa is an umbrella-shaped and free-swimming form, like Aurelia.
- Alternation of Generation (Metagenesis) exists in cnidarians exhibiting both polyp and medusa forms, where polyps produce medusae asexually, and medusae form polyps sexually.
- Ctenophores are exclusively marine, radially symmetrical, diploblastic organisms.
- Ctenophores have eight external rows of ciliated comb plates for locomotion.
- Bioluminescence, the property of emitting light, is common in ctenophores.
- Platyhelminthes have a dorso-ventrally flattened body and are called flatworms.
- Platyhelminthes are bilaterally symmetrical, triploblastic, and acoelomate animals.
- Arthropoda have a jointed exoskeleton of chitin, complete digestive system, and an open circulatory system.
- Mollusca are soft-bodied animals with a calcareous shell, unsegmented body, and a mantle cavity.
- Mollusca have a file-like rasping organ called a radula for feeding.
- Echinodermata have a water vascular system and radial symmetry.
- Hemichordata have a worm-like body with a proboscis, collar, and trunk.
- Chordata have a notochord, dorsal hollow nerve cord, gill slits, and limbs or fins.
- Amphibia are cold-blooded vertebrates that live in both aquatic and terrestrial environments.
- Reptilia are mostly terrestrial animals with dry and cornified skin, epidermal scales, or scutes.
- Reptilia have a three-chambered heart (except crocodiles which have a four-chambered heart).
- Aves (birds)Â are characterized by feathers, beaks, and wings.
- Aves have a four-chambered heart and are warm-blooded.
