Study Notes
Animal Classification and Important Terms
- Larva: Found in both vertebrates and invertebrates.
- Poikilotherms: Also known as ectotherms.
- Plankton: Animals/organisms floating on the water surface.
- Radial symmetry: Body can be divided into identical halves in only one plane.
- Asymmetry: Organisms attached to substrata generally possess asymmetric bodies.
Animal Characteristics
- Non-chordates: Lack a notochord, dorsal tubular nerve chord, pharyngeal gill slits and hepatic portal system.
- Cell aggregate plan: Found in Cnidarians.
- Deuterostomes: Spiral cleavage, blastopore becoming the mouth.
- Protostomes: Mouth develops first during embryonic development.
- Ectotherms: Cold-blooded animals.
- Endotherms: Warm-blooded animals.
Animal Body Plans
- Tube-within-a-tube body plan: Found in Coelenterates, Platyhelminthes, Aschelminthes (Nemethelminthes), and Porifers.
- Blind sac body plan: Found in roundworms.
- Coelomate: Food diffuses from gut to tissues by coelomic fluid.
Other Key Facts
- Important terms:
- Enterocoelous coelom: Found in deuterostomia.
- Facultative parasites: Live without a host.
- Nocturnal animals: Active at night.
- Diurnal animals: Active during the day.
- Radial symmetry: Fishes, Star fishes, Molluscs,Sponges.
- Common characteristics
- Earthworm: Hermaphrodite, smaller male.
- Echinoderms: Protostomatous coelomates.
- Human teeth: Anatomically comparable to shark scales.
- Hair: A skin derivative.
- Enterozoa: Includes Annelida, Mollusca, Porifera, Echinodermata, Hemichordata.
- Cold-blooded/warm-blooded animals: Ectotherms/Endotherms.
