Study Notes
Classification of Animals
- Animals are classified into over 30 phyla based on shared traits and diversity.
- Estimated over a million species of animals exist on Earth, showcasing vast diversity from simple to complex organisms.
Major Animal Phyla
- Phyla listed contain at least 10,000 species each:
- Porifera: Includes sponges.
- Cnidaria: Comprises jellyfish and corals.
- Platyhelminthes: Contains flatworms, tapeworms, and flukes.
- Nematoda: Consists of roundworms.
- Mollusca: Includes snails, clams, and squids.
- Annelida: Comprises earthworms, leeches, and marine worms.
- Arthropoda: Includes insects, spiders, crustaceans, and centipedes.
- Echinodermata: Contains sea stars, sea urchins, sand dollars, and sea cucumbers.
- Chordata: Encompasses tunicates, lancelets, fish, amphibians, reptiles, birds, and mammals.
Invertebrates vs. Vertebrates
- The first eight phyla are exclusively invertebrates, lacking a backbone or vertebral column.
- Phylum Chordata includes both vertebrate and invertebrate species, such as tunicates and lancelets.
- Invertebrates constitute at least 95% of all animal species.
- Vertebrates, which have a backbone, are all classified under the phylum Chordata.
- Vertebrate groups include fish, amphibians, reptiles, birds, and mammals.
