Concept explainers
To enlist:
The characteristics and representatives of the given animal phyla.
Introduction:
Animal phyla include a list of the major groups of animals that include invertebrates and vertebrates. Invertebrates are the animals that do not have a backbone and the vertebrates are the backbone bearing animals.
Explanation of Solution
The key characteristics and the representatives of the animal phyla are described in the following table.
Phylum |
Characteristics |
Representatives |
Sponges |
They are included in phylum porifera. It is a simple animal with no mouth, heart or muscles. It is sessile animal containing many pores and cells for filter feeding. Asymmetrical. |
Sponges and common bath sponge. |
Cnidarians |
They are aquatic animals. Coelom is absent. They contain cnidocyte cells to capture prey. Radial symmetry. |
Sea anemone, jellyfish, corals and Obelia. |
|
Included in phylum Platyhelminthes. No body cavity. Bilateral symmetry. |
Planaria and tape worms. |
Nematodes |
They have complete |
Roundworms and hookworms. |
Molluscs |
They have a soft and unsegmented body. Have mantle and the muscular foot. |
Snails, squids, octopus and mussels. |
Annelida |
They are the true segmented worms. Have closed circulatory system. |
Earthworms and leeches. |
Arthropods |
Presence of jointed legs, antennae, exoskeleton and closed circulatory system. Bilateral symmetry. |
Insects, crab and millipedes. |
Echinoderms |
They have spiny skin, water vascular system, body containing 5 equal segments and tube feet. Radial symmetry. |
Star fish and sea urchin. |
Chordates |
Presence of notochord, dorsal nerve chord, gill slits and bilateral symmetry. |
Mammals, fish, birds, reptiles and amphibians. |

Charles a Biology student in California has found at the beach an animal he cannot name. What are some of the questions that he should ask to help determine the phylum of the animal? Based on the data that you recorded during this lab do you see a relationship between symmetry, cephalization, and number of germ layers? Can you tell what germ layer appears last? Name three characteristics or features in the phyla studied that you could tell are ancestral or primitive and three that you may call advance?
