Introduction To Classification

Classification is the act of distributing things into classes or categories of the same type.

slide3

About Classification

  • Aristotle was the first to form a useful form of classification in 300 B.C.
  • His was organized on the organisms blood color.
  • Then he later organized by physical characteristics.
slide4
As science advanced, a more modern form of classification developed…
  • One founder of modern classification is Swedish naturalist Carolus Linnaeus.
  • He developed a system that organized by special features an organism had.
  • He also founded binomial nomenclature for naming.
slide5
The modern classification system has become much more advanced.
  • Classification makes everyday life easier by putting organisms in a useful system.
  • Classification helps us to group the organisms we live with every day.
  • Classification also lets us have a system for reference and will continue to help as we study the organisms around us.

The Shark

*Cartilaginous- skeleton of cartilage

*Aquatic- lives in water

*scales/denticles- small flat plates that fit together to form skin covering (tooth shaped)

*lateral line- sensory organs along side of fish to help navigate and sense other creatures

*gill filaments-threadlike; part of gills that are filled with blood vessels; where they basically breathe

*gill cover- bones (cartilage) of fish’s head that cover gills

Family Rhincodontidae

This is the whale shark. It belongs to family rhincodontidae. Like all sharks, the whale shark is cold-blooded. The whale shark can be 18 meters in length and exceed 10 tons! The whale shark mainly feeds on plankton, sardines, squid, and anchovies. It resides mostly in Western Australia. Whale sharks are often confused with whales because of their size and non-violent tendencies.

Family Hexanchidae

This is the cow shark. It is part of the family Hexanchidae. Cow sharks can be about 3 to 4 meters long. They usually live deep down in warm, temperate seas. Cow sharks can have anywhere from 22 to 108 pups at a time!

slide43

Why we use Classification

Classification helps scientists characterize traits and specifics on organisms.

We use classification to put all of earth’s known organisms into group and families.

Dichotomous Keys help us to figure out what genus and species an animal falls under.

For example, if a new organism was discovered, a scientist would go through a Dichotomous Key to try to find out the subject’s kingdom, phylum, class, order, family, genus, and species.
