(Gen) Animal Characteristics

Learn animal phyla! Match characteristics, identify symmetry, and track evolutionary steps.

Animal Phylum vs. Description of Characteristics Match the animal phylum with the correct description Cnidarian Jelly like animals that have a bell or umbrella shape (often sting their prey) Chordates Animals that have a notochord that supports the body (or a backbone) Mollusca Soft bodied animals that usually have a shell Arthropod They have three body parts, jointed legs, and a tough exoskeleton made of chitin Echinoderm These marine animals have plates with spines Annelids Long animals divided into segments Platyhelminthes Soft, thin, flat bodies Example animals and their phylum names Write the correct phylum name next to the animal below that it is.Word Bank (type exactly as appears here): Platyhelminthes, Cnidarian, Chordata, Mollusca, Annelida, Echinoderm, Arthropod Annelida Platyhelminthes Cnidarian Chordata Mollusca Echinoderm Arthropod Animal Symmetry: Place the animal under the type of body symmetry it has. Definition:Asymmetrical: having parts which fail to correspond to one another in shape, size, or arrangement; lacking symmetry.Radial: symmetry around a central axisBilateral: the property of being divisible into symmetrical halves on either side of a unique plane. Asymmetrical Sponge Radial Anemone Jellyfish Starfish Bilateral Snail Fish Earthworm Frog Alligator Crayfish Ant Elephant Phylum Name and the Evolutionary Advance Match the correction phylum name to the next step in evolutionary milestones they had.Definitions:Notochord: a cartilaginous skeletal rod supporting the bodyDeuterostome: any member of the phyla in which the anus appears first, developing at or near the blastopore.Coelom: the body cavity located between the intestinal canal and the body wall.Pseudocoelom: a fluid-filled body cavity lying inside the external body wall of the nematode that bathes the internal organs Porifera Multicellularity Chordata Notochord Annelid Segmentation Cnidarian Tissues Echinoderms Deuterostome Mollusca Coelom Platyhelminthes Bilateral Symmetry Nematoda Pseudocoelom Arthropod Jointed appendages
