Marine biology is the scientific study of organisms in the ocean or other  marine bodies of water. 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.

i like this topic because i like the mysteries that the marine life has. i like the life that the oceans have. the reason why i like this subject is that you learn something every day. you get to know the animals that are in the world. and also you get to find some discoveries in this subject that may help humans and animals.
