Life in oceans and coastal waters is a dynamic and diverse ecosystem that sustains an incredible array of marine organisms. These habitats, teeming with an abundance of flora and fauna, play a crucial role in maintaining the delicate balance of our planet's biodiversity. Oceans cover more than 70% of the Earth's surface, providing a vast and complex environment where marine life thrives. From microscopic plankton to majestic whales, the interconnected web of life in these waters showcases the resilience and adaptability of aquatic species. Coastal regions, where land and sea meet, host unique ecosystems supporting an array of marine life while influencing climate patterns and human livelihoods. As we explore the wonders of life in oceans and coastal waters, it becomes imperative to understand and preserve these environments for the benefit of both the marine world and our global ecosystem.
