The difference between a lizard and a salamander is that a lizard is a reptile and a salamander is an amphibian. Reptiles live solely on land, while amphibians spend part of their time in the water. Hence amphibians need to be near a source of water while reptiles don't.Know More
The skin of a salamander is soft, permeable and lacks scales. Like other amphibians, salamanders secrete mucous over their skin to help it retain moisture. Some salamanders have potent toxins in their skin. They lay their shell-less eggs in jelly-like masses either in still water or in a moist place like leaf mold. The eggs hatch into larvae who live in the water and breathe through gills. As they grow, their lungs develop and they are able to leave the water and breathe air. Some salamanders, however, retain their gills even in adulthood.
Lizards have scaly skin that helps them keep in water. They don't need to live near ponds, lakes or streams, and many species of lizards live in deserts. Their eggs are amniotic and are protected by shells that are hard or leathery. When the eggs hatch, the young are miniatures of their parents and don't undergo metamorphosis. Lizard toes are clawed, which is not true for salamanders.Learn more about Zoology

The main difference between parasites and predators is that the former are organisms that live at the expense of another organism, called the host, while the latter capture and feed on another organism, called the prey. The Australian Museum explains that parasites are generally smaller than their host, whereas predators are typically larger than their prey. Moreover, parasites do not kill their host, but predators often kill their prey.Full Answer >
While taxonomy is the classification and naming of all living things, systematics refers to the study of the relationships between these living things as they evolve. Taxonomic hierarchy was devised and published by Swedish scientist Carl Linne in 1735. All branches of systematics, such as botany, zoology, microbiology and mycology, are covered under taxonomy. Taxonomy as the science of biological classification is a subdivision of systematics.Full Answer >
