What is classification? In 1735, Swedish scientist Carl Linnaeus first published a system for classifying all living things. An adapted version of this system is still used today: The Linnaeus System. It is used by sorting animals into groups; for example, a dog is a mammal because it has lungs to breathe ,they are warm-blooded, they can live outside of water, it gives birth to live young and feeds it’s young using it’s own milk. Frogs are amphibians because they have four legs when fully developed, they can breathe underwater for an amount of time and are warm blooded. They are sorted into different groups because they are not like each other. Dogs are warm-blooded but frogs are cold-blooded, dogs have fur and frogs don’t.
How are living things classified? Animals are classified by being put into groups: mammals , amphibians , reptiles , birds , fish , and insects. Amphibians have four legs when fully developed. They are cold blooded and can breathe underwater for an amount of time. Reptiles lay eggs and are the most lived species on the planet. They do not birth live young however, the do lay many eggs at once or a small period of time. Birds are warm blooded most can fly , they lay eggs and have beaks. Fish V.S insects? They are both cold blooded and lay eggs. However, the way they display their eggs are very different. Fish hide them in the sand whereas insects hide them under leaves. Fish live entirely underwater and have gills and fins so they can breathe without lungs like humans. Insects have an exoskeleton but fish don’t and fish have a back bones insects don’t. Examples Mammals: horse, rabbit, humans… Amphibians: axolotls , frogs , torrents… reptiles: turtles , torrents… birds: bluetit , kite , ducks… fish: carp , tuna , sea bass… insects: flying ant , lady bug… An informative blog sharing your knowledge on classification.
