Some animals migrate to breed. The Atlantic Salmon begins its life in a river and migrates downstream to the ocean.
What are the 2 main animal groups?
Vertebrates and Invertebrates Because there are so many different types of animals in the world biologists have sorted them into groups. This is called classifying. The two main groups of animals are vertebrates and invertebrates. Vertebrates are all animals with a backbone.
What is the biggest migration of animals?
Arctic terns hold the record for the longest annual migration recorded by any animal. Moving between Greenland and Antarctica in a zig-zag route, the bird covers 44,000 miles a year.

How do humans impact animal migration?
Humans have an impact on species migration both through climate change and by changing the landscape. Both plants and animals will have to respond to the changing climate. In some cases, this means adapting to higher temperatures.
How many different types of animals are there?
First, we don’t even know how many types of animals there are in the world, let alone how many individual animals there are. Scientists have recently estimated that there are approximately 8.7 million species on Earth. They believe that 1-2 million of those species are animals.

Because of economic restructuring, job prospects often vary from one country to another and within regions of the same country.
How does migration affect evolution?
Migration. Migration is the movement of populations, groups or individuals. In genetic terms, migration enables gene flow: the movement of genes from one population into another. Migration will generally unify gene frequencies among populations rapidly in evolutionary time.
What are the types of birds that migrate?
These can include the vast majority of North American bird species such as vireos, flycatchers, ruby-throated hummingbirds, ducks, geese, swans, tanagers, Blackburnian Warblers, orioles, Arctic Terns and swallows. Nomadic/Irregular Migrants – These birds only follow the food.
