Marine biology is the study of animal and plant life within saltwater ecosystemsgiven that in biology many phyla families and genera have some species that live in the sea and others that live on land marine biology deals with those species in which life is spent only or mainly in the water thus its classification is based on the environment rather than on. Biology means the study of life and ecology is the study of how life interacts in an environment.

As a marine biologist you may study a wide range of topics from the behavior physiology and ecology of specific groups of organisms to the interactions between human activity and aquatic environments. The use of marine biology to study practical problems such as pollution or the use of biological structures to protect against wave surge. Given that in biology many phyla families and genera have some species that live in the sea and others that live on land marine biology classifies species based on the environment rather than on taxonomy.

Understanding the life cycles habits habitats and inter-relationships of marine life contributes to our understanding of the planet as a whole. The phrase marine life refers to organisms that live in salt water. At a fundamental level marine life helps determine the very nature of our planet.
