1 Kingdom Animalia

2 ~ Characteristics ~ Multicellular Multicellular Eukaryotic with no cell walls Eukaryotic with no cell walls Heterotrophs (consumers) Heterotrophs (consumers)

3 ~ Characteristics ~ Have a nervous system to respond to their environment Have a nervous system to respond to their environment Locomotion relates to ability to obtain food Locomotion relates to ability to obtain food Most animals develop from a zygote becoming a Most animals develop from a zygote becoming a A single layer of cells surrounding a fluid- filled space forming a hollow ball of cells called a gastrula A single layer of cells surrounding a fluid- filled space forming a hollow ball of cells called a gastrula.

4 ~ Developmental Characteristics ~ The gastrula is made up of three parts: The gastrula is made up of three parts: –Ectoderma layer of cells on the outer surface of the gastrula, grows and divides developing into skin and nervous tissue. –Ectoderm, a layer of cells on the outer surface of the gastrula, grows and divides developing into skin and nervous tissue. –Endoderma layer of cells lining the inner surface of the gastrula, develops into the lining of the animals digestive tract. –Endoderm, a layer of cells lining the inner surface of the gastrula, develops into the lining of the animals digestive tract. –Mesoderm, made up of two layers of cells lying between the ectoderm and endoderm, forms muscles, reproductive organs and circulatory vessels.

6 ~ Developmental Characteristics ~ Animals that develop a mouth from the indented space in the gastrula are protostomes. Animals that develop a mouth from the indented space in the gastrula are protostomes. Animals that develop an anus from the opening in the gastrula are deuterostomes. Animals that develop an anus from the opening in the gastrula are deuterostomes.

8 ~ Body Plans ~ Animals that are irregular in shape are asymmetrical. Animals that are irregular in shape are asymmetrical. Animals that are regular in shape are symmetrical. Animals that are regular in shape are symmetrical.

9 ~ Body Plans ~ An animal has radial symmetry if it can be divided along any plane, through a central axis, into equal halves. An animal has radial symmetry if it can be divided along any plane, through a central axis, into equal halves. An animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming mirror images of each other. An animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming mirror images of each other.

10 Which figure has bilateral symmetry? Which has radial symmetry?

11 ~ Body Plans ~ Acoelomates – animals have three cell layers with a digestive tract but no body cavities. Acoelomates – animals have three cell layers with a digestive tract but no body cavities. Pseudocoelomates – animals with a fluid- filled body cavity partly lined with mesoderm. Pseudocoelomates – animals with a fluid- filled body cavity partly lined with mesoderm. Coelomates – animals with a body cavity completely surrounded by mesoderm. Coelomates – animals with a body cavity completely surrounded by mesoderm.

13 ~ Protection and Support ~ Though not all animals have a skeleton, those that do can be divided into two groups: Though not all animals have a skeleton, those that do can be divided into two groups: –Those with an exoskeleton – a hard, waxy coating on the outside of the body that protects internal organs, provides a framework for support, and a place for muscle attachment. –Those with an endoskeleton – support framework within the body that protects some organs and a brace for muscles to pull against.

14 ~Invertebrates~ 8 main phyla 8 main phyla No backbones No backbones 95% of all animals are in this group 95% of all animals are in this group

15 ~Invertebrate Phylum Porifera~ Sponges Sponges simplest form of animal life simplest form of animal life live in water live in water Do not move around Do not move around no symmetry no symmetry Pores (holes) all over body Pores (holes) all over body 5000 species 5000 species

16 ~Invertebrate Phylum Porifera~ Filter Feeders: a sponge filters particles of food from water using collar cells and then pumps the water out the osculum. Filter Feeders: a sponge filters particles of food from water using collar cells and then pumps the water out the osculum.
