Marine life refers to the diverse range of organisms that inhabit the world's oceans and seas. This includes a variety of species such as fish, mammals like whales and dolphins, invertebrates like jellyfish and octopuses, and coral reefs that provide essential habitats. These organisms play crucial roles in the marine ecosystem, contributing to the balance of life in aquatic environments. The ocean is home to approximately 230,000 known species, but scientists estimate that millions more remain undiscovered. Marine life is vital for human survival, providing food, oxygen, and regulating the climate. Protecting marine ecosystems is essential for maintaining biodiversity and ensuring the health of our planet.
