Marine zoology is the study of animals that inhabit marine ecosystems, including fish, mammals, invertebrates, and crustaceans. This branch of zoology examines the anatomy, behavior, and ecological roles of marine species, contributing insights into biodiversity, adaptation, and evolutionary processes. Research in marine zoology helps understand how marine animals interact with their environments and adapt to changing conditions, particularly in the face of climate change and pollution. Knowledge gained from marine zoology aids in the conservation and sustainable management of marine resources, ensuring that the benefits derived from marine biodiversity are preserved for future generations.
