Study Notes
Animal Diversity and Anatomy
- Scientists have cataloged approximately 2 million animal species
- The exact number of animal species is unknown
- Familiar animals include cats, dogs, horses, elephants, dolphins, turtles
- Less-familiar species are often confused with plants
- Systematics names and classifies species based on evolutionary relationships, anatomy, physiology, and DNA
- Closely related species are grouped into genera, families, orders, classes, phyla, kingdoms, and domains
- The Animalia kingdom belongs to the Eukarya domain
- Scientific names consist of two Latin words: the genus capitalized, the species lowercase, both italicized or underlined
- Examples of correctly written scientific names include Canis Familiaris and Zea Mays. Melanoplus femurrubrum, Cedrus libani, Eschiarichia coli, pinus densifolia, drosophila melanogaster, Larrea Tridentata and Caenoharbditis elegans, Ferocactus cylindraceus
The Classification of Animals
- Animals are classified into many phyla
- New discoveries lead to changes in classifications and new phyla
- Newly discovered species are often added to existing classifications
- Major characteristics distinguish one phylum from another
- Symmetry: some animals lack symmetry, others have different types (radial or bilateral)
- Humans have bilateral symmetry
- Jellyfish have radial symmetry
- Skeleton: internal (humans) or external (insects), or hydrostatic (fluid pressure)
- Appendages: occur in pairs in most animals
- Digestive system: one opening (gastrovascular cavity) or two openings (alimentary canal)
- Additional characteristics further distinguish phyla
Phylum Porifera
- The phylum Porifera (sponges) has many species
- Members of this phylum are called sponges
- Key characteristics:
- Lack of tissues and organs
- Pores for water passage
- Filter-feeding
- Choanocytes (collar cells) for feeding
- Reproduce sexually and asexually
- Divided into 3 classes
Phylum Cnidaria
- Cnidarians have many species
- Common names include jellyfish, corals, sea anemones
- Key characteristics:
- Radial symmetry
- Tentacles with stinging cells (cnidocytes) containing nematocysts
- Simple body structure (polyp or medusa form)
- Gastrovascular cavity for digestion
- Do not have brains
Phylum Platyhelminthes
- Platyhelminthes (flatworms) have many species
- Common names include flukes, tapeworms
- Key characteristics:
- Bilateral symmetry
- Flattened body shape
- One opening digestive system
- Simple nervous system
- Some species can cause diseases in humans
- Can reproduce sexually and asexually
Phylum Arthropoda
- Arthropods have many species
- Common names include insects, spiders, crustaceans
- Key characteristics:
- Exoskeleton
- Segmented body
- Jointed appendages
- Versatile
- Have brains and various respiratory and circulatory systems
Animal Anatomy: Circulatory System
- The circulatory system transports nutrients and wastes through the body
- The main components are the heart, arteries, veins, and capillaries
- The heart pumps blood
Animal Anatomy: Digestive System
- The digestive system breaks down food and absorbs nutrients
- Includes structures such as the esophagus, stomach, small intestine, rectum and anus, pancreas, liver, and gall bladder
Animal Anatomy: Reproductive System
- The reproductive systems of males and females have different structures
- Include parts like ovaries, fallopian tubes, uterus, cervix, vagina in females; testes, epididymis, vas deferens, prostate, seminal vesicles, urethra, and penis in males
Animal Anatomy: Skeletal System
- The skeleton provides support and structure
- Examples of bones include sternum, scapula, ribs, clavicle, vertebrae, pelvis, coccyx, humerus, femur, and manubrium
Frog Dissection
- Identification of the frog's eardrum, respiratory system (lungs), circulatory system (heart), and other internal organs
- Includes mouth, tongue, intestines, stomach, liver, pancreas, cloaca, and other organs.
