Taxonomy
: science concerned with the naming & classification of organisms. Carolus Linnaeus, a Swedish botanist, is credited with the development of our modern method of classification called binomial nomenclature. (Genus, species) Kingdom-Phylum-Class-Order-Family-Genus-Species All organisms are divided into one of five kingdoms: 1.) Monera ~ bacterial organisms that lack a true nucleus in the cell and reproduce by fission (splitting apart).
2.) Protista ~ single-celled or microscopic animals, including algae 3.) Plantae ~ mutlicellular photosynthesizing organisms, higher plants, and multicellular algae 4.) Fungi ~ molds, yeast, & fungi 5.) Animalia ~ composed of vertebrates & invertebrates
*All animals we will study this year belong to the phylum Chordata. All members of this phylum have four distinctive characteristics: 1.) an embryonic notochord, which is usually replaced by the spinal cord 2.) a dorsal tubular nerve cord running down the back side 3.) pharyngeal or throat area gill slits 4.) a rear area tail *****(Although they possess these structures at some embryonic stage, these characteristics may be altered or disappear in later stages of life.)**
All animals we will look at belong to one of four classes: 1.) Mammalia: vertebrates that possess mammary glands, have a body that’s more or less covered in hair, and a well- developed brain.
2.) Reptilia: includes snakes, lizards, and turtles. Comprises cold blooded vertebrates having lungs, an entirely bony skeleton, a body covered with scales or horny plates, and a heart with two atria and a single ventricle.
3.) Aves: class for birds. These are warm-blooded vertebrate animals with two legs, wings, feathers, and lay eggs.
4.) Osteichthyes: bony fish. This is a large group of vertebrate animals that live in water and have permanent gills for breathing, fins, and a body usually covered with scales.
The domestic dog would be classified as follows: Kingdom – Animalia Phylum – Chordata Genus – Canis Species – familiaria (animal kingdom) (animals w/ vertebrates) Class – Mammalia (animals that suckle young) Order – Carnivora (flesh or meat eaters) Family – Canidae (dog family including wolves, foxes, & coyotes) (dogs) (domestic dog)
Using textbooks, computers, and your new knowledge of binomial nomenclature, find the complete classification of
5 different animals.
