What are some examples of species?
Humans ( Homo sapiens ), moose ( Alces laces ), black bears ( Ursus americans ), jack pines ( Pinus banksiana ) are all examples of different species.
There are multiple definitions of what exactly is a species. Thus, there are instances in which one species is considered two species by a different group of scientists, and there are instances when determining if something is a new species is challenging, for example, in hybrid zones.
Examples of widely recognized species include
The Australian ant (Nothomyrmecia macrops )
Staghorn coral (Astreopora expansa)
There are many more species yet to be discovered, particularly insects, plants, and other non-mammal species.
