InvertebratesGoal: Students will know the 8 invertebrate phyla.

Each animal phylum has a unique body plan.

Animals! Goal: Students will be able to list the characteristics of animals and identify the 3 types of symmetry.

Invertebrate Overview. Body Symmetry Radial Symmetry-body parts that repeat around center body-Cnidaria and Echinodermata Bilateral Symmetry-imaginary.

Welcome to…. THE ANIMAL KINGDOM Multicellular heterotrophs with tissues.

Kingdom Animalia. All members of Kingdom Animalia share several common characteristics Multicellular eukaryotes Heterotrophic (must eat) Produce sex cells.

The Animal Kingdom- 9 Phyla. Terminology  Symmetry- –Divisible into similar halves.

9 Phyla of the Animal Kingdom. Common Animal Characteristics Multicellular (many cells) Multicellular (many cells) Eukaryotic (cells contain nucleus)

Anamalia Phyla Characteristics. Phylum Porifera System of pores through which water passes and food is captured Sponges are either radially symmetrical.

9 Phyla of the Animal Kingdom

Kingdom Animalia. Animalia Characteristics Multicellular Eukaryotic Heterotrophs No cell walls, structurally supported by collagen Mostly Sexual reproduction.

General Characteristics Multicellular No cell walls (bodies are held together by proteins such as collagen). Often contain specialized tissue such as.

Asymmetry Animals have different patterns of symmetry, the arrangement of body parts around a central axis Asymmetry – no general body plan Example: Sponges.

ANIMAL KINGDOM CLASSIFICATION Animals can be grouped into two large categories: Vertebrates and Invertebrates. Vertebrates have backbones and invertebrates.

Invertebrates A Survey of Invertebrates. Trends in Invertebrate Evolution Common ancestors of multicellular animals had already evolved two distinct cell.

What is an Animal? Eukaryotic (complex cells) Multicellular (made of many cells) Heterotroph (obtain food from outside) swallow and digest inside the body.

MARINE BIOLOGY SYMMETRY OF ANIMALS

ASYMMETRY WITHOUT SYMMETRY OF BODY ORGANS VERY SIMPLE BODY PLAN GROW ACCORDING TO ENVIRONMENT EX: PORIFERA I got nothin’ but pores!

RADIAL SYMMETRY CIRCULAR PATTERN BODY RADIATES FROM CENTER POINT PROVIDES PROTECTION AND RESOURCES ALL AROUND BODY EXAMPLES: CNIDARIA, ECHINODERMATA My mouth is in the center of my body!

BILATERAL SYMMETRY MOST ADVANCED BODY PLAN BODY IS DIVIDED INTO 2 HALVES HAVE HIGHLY SPECIALIZED ORGANS EXAMPLES: CORDATA, MOLLUSCA, ARTHROPODA, ANNELIDA, NEMATODA I’ve got two eyes! I’ve got two claws!
