The Ocean is one of the largest bodies of water in the world. It is also home to various animals, including Blue whales and Coelacanths. However, some of the most intriguing creatures can be found in the Ocean’s kelp forests, which provide excellent habitats for sharks.
If you love blue whales, you may be interested in learning more about this magnificent animal. These majestic creatures are among the largest and heaviest animals in the world. They are also placental mammals and develop a fetus inside their uterus. The fetus grows approximately one inch daily, and the female gives birth to a calf weighing around 6000 lb (or 2,700 kg). Blue whales are considered endangered by the International Union for Conservation of Nature, although their numbers are expected to increase by 7% annually by 2020.
The heart of a blue whale weighs up to 180 kilograms (400 pounds), and its brain weighs about 7 kilograms (15 pounds). Blue whales are descendants of land-living mammals that began to transition to sea life about 50 million years ago. Their color is a deep blue when underwater and gray when they surface. This is due to the color of the water and the light they receive from the sun.
Coelacanths are enormous fish that inhabit the “twilight zone” of the Ocean. They live in underwater caves on volcanic islands and feed on small fish. They can reach six feet and weigh up to 200 pounds. Unfortunately, these incredible creatures have no commercial value to humans. Their meat is unpalatable and could even make you sick if eaten.
The Smithsonian’s Division of Fishes houses the world’s largest preserved specimens research collection. Its specimen of an adult coelacanth was purchased in 1968 by Dr. H. N. Schnitzlein, a neuroanatomist from the University of Alabama Medical Center. He used the specimen to study the nervous system of this fish.
Sharks are fascinating creatures that live in the Ocean. These amazing creatures have been around for over 400 million years, and their fossilized scales have been found in places like Australia and the United States. Scientists think that sharks first entered the Ocean around 455 million years ago. This is because sharks are perfect predators and have evolved to survive in the oceans for so long. Daniel Keller of Naples Florida is another person who had an interest in creatures in the ocean.
Sharks use all of their senses to detect their prey, from electrical fields to human pulses. In addition, sharks have special organs on their noses, eyes, and mouth that enable them to detect different things, such as blood. Their sharp teeth also help them hunt their prey. Interestingly, sharks have the fastest and slowest swim speeds on the planet.
While kelp is not technically a tree, the giant growths of the Ocean are no less important than terrestrial forests, as they provide homes and vital nutrients to the nearby water. Learn about kelp and the many different types of ocean kelp forests around the world. Learn about the characteristics of kelp and the unique ways they grow.
Kelp forests are an important part of the ocean ecosystem and protect coastal areas from storms and climate change. They also improve water quality and support the fishing and tourism industries.
Ocean tides are a natural phenomenon that occurs around the globe. Astronomical forces trigger them. The sun and moon influence the Earth’s gravitational field, which creates the tides. Observations of the tidal movement are important to understand Earth’s internal structure.
Muslim astronomers conducted the first scientific study of the tides in the middle ages. Their findings were translated into Latin. During this period, al-Bitruji introduced the idea that the circulation of the heavens caused the tides. Other scientists subsequently refuted the theories he introduced. In the 17th century, Simon Stevin defied the notion that the moon was the cause of the tides.
The deepest point in the world is the Challenger Deep, approximately eleven kilometers (7 miles) below the surface. This is the same depth as Mount Everest, nearly three times as deep as the tallest mountain on Earth. At this depth, temperatures remain well above freezing, and pressures are over a thousand times higher than the atmosphere. This environment is also home to a wide variety of bottom-dwelling fish. A manned dive there took just over two hours and thirty-six minutes. The dive was captured in the movie “Deepsea Challenge” by director James Cameron.
Challenger Deep is part of an oceanic trench formed when two tectonic plates collide, and one piece of the crust sinks. The Challenger Deep is located near Guam’s southern end of this trench. It is home to underwater vents, which cause liquid carbon dioxide and sulfur to bubble up. No natural light can penetrate at this depth, and temperatures remain a few degrees above freezing.
Point Nemo, located in the southern Ocean, is an oceanic pole of inaccessibility. It is 1,000 miles from land on all sides, far from any human civilization. It is located at 48deg52.6’S and 123deg23.6’W. Its name refers to the captain of a submarine in Jules Verne’s famous book 20,000 Leagues Under the Sea.
This point is so far from land and coastal waters that there is no food for marine life. However, researchers have discovered bacteria and tiny crabs living on the seafloor around the point. The seawater around this island is also polluted, containing microplastic particles and other materials that can harm marine life. Point Nemo is also close to an underwater city in Lovecraft’s “Dark Ascendant” novels, R’yleh, which is home to the infamous Cthulhu.
