Biological classification of organisms |
In the science world, a binomial nomenclature system is used to give every species its own scientific name. This is not only important because it identify a species, but it also serves to avoid confusion as to what is what, so the universal scientific naming system ensures that everybody that speaks that language refer to a given species using a single name, which normally is partly Latin. Again, referring to the most popular scientific name for humans called Homo sapiens. The first name or the genus, always starts with a capital letter and tells you the species it is closely related to, for instance Homo - referring to organisms with an s-curved spine, in other words (human family). VertebratesVertebrates are organisms with a backbone. As you study biology, here are main classes of vertebrate you will be dealing with: Reptiles - Have very dry scales, lungs. In addition to that, they also Soft, rubbery egg shells.(e.g snakes, crocodile) Fish - Has wet scales, gills and fins. They also have jelly-like eggs. Amphibians - Have very soft and damp skin. Many are believed to be able to breathe through their skin (e.g frogs) Birds - They have feathers and lay eggs with hard shells. Most have wings too.(e.g chickens, dove) Mammals - They have hair and feed their young with milk.(e.g humans, cattle) InvertebratesInvertebrates are organisms with no backbone. Bellow are some of the invertebrates you are going to deal with. arthropods - These are a large group of invertebrates with a hard exoskeleton and jointed legs. Below are some of the common members of this group and their characteristics: Insects - Have 6 legs and 3 parts to the body. (e.g flies and ants) Crustaceans - They usually have 10 or more legs and has a hard shell.(e.g crabs) Arachnids - has 8 legs and 2 parts to the body.(e.g spiders and scorpions ) |
