It's a vast aquatic territory with diverse ecosystems and marine species.Oceans cover about 70% of the Earth's surface. This means that most of our planet is underwater. These bodies of water play a crucial role in supporting life by regulating climate, providing habitat for a multitude of species, and much more.The blue whale is the largest marine creature and also the largest animal that ever lived. It can reach up to 100 feet long and weigh as much as 200 tons. Despite their size, blue whales feed mostly on tiny shrimp-like animals called krill.The Mariana Trench is located in the western Pacific Ocean and is the deepest part of the world's oceans. It reaches a maximum-known depth of about 36,000 feet. This depth makes the environment hostile and only specialized organisms can survive.The Arctic Ocean is the smallest and shallowest of the world's five major oceans. Despite its smaller size, it plays a crucial role in global climate regulation, particularly in terms of temperature and humidity.The Great Barrier Reef, located off the coast of Queensland, Australia, is the world's largest coral reef system.

Other terms include smack or swarm.

Despite their enormous size, reaching up to 40 feet, they are gentle and feed mostly on plankton.

They are estimated to live over 200 years, with some even reaching the age of 211. This longevity is due to their slow growth rate and cold environment which slows their metabolism.Staghorn corals are among the fastest growing corals, capable of growing up to 20 cm per year. This rapid growth is vital as it helps in reef recovery and resilience against threats such as climate change, coral bleaching, and disease.Bioluminescence is a phenomenon seen in many marine organisms where they emit light as a result of a chemical reaction within their bodies. This light can be used for various purposes such as hunting, attracting mates, or self-defense.The moon's gravitational pull causes tides in the ocean. When the moon is closest to Earth, its gravitational pull is stronger, causing high tides. When it's farthest, the pull is weaker, resulting in low tides. The sun's gravity also contributes but to a lesser extent.There's no such thing as cyanoplankton. Phytoplankton are photosynthesizing microscopic organisms, zooplankton comprise tiny drifting animals, and bacterioplankton are bacteria.
