There are some unimaginable and incredible creatures inside the ocean waters. Some species give us pleasure with the way they camouflage themselves, their exceptional colors, or even their special shapes. The most remarkable feature that has been capturing the eye of many people over decades is the massive size of some ocean creatures. In the next lines, we will display to you the 10 largest sea creatures already existing in this world:    


Blue Whale: 108 feet (33 meters) 

Its technical name is Balaenoptera musculus, the blue whale is the largest mammal that has ever existed in history. Their size is equivalent to the weight of 33 elephants. Their heart is the size of a Volkswagen Beetle. They are the loudest animal in the world. Their low-frequency whistles can be heard through hundreds of miles and it's probably used to attract another blue whale. Their weight is up to 441,000 pounds and when stretched may length half of a football field.    


Lion’s Mane Jellyfish: 120 feet (36.6 meters) 

If the Blue Whale has received the title as the largest animal in ocean, the Lion’s Mane Jellyfish is considered as the longest animal in ocean water. Their tentacles may reach up to 120 feet (more than 30 meters) and they are completely filled with poison that stun prey when they are enveloped. Most lion’s mane jellyfish live in the Arctic and North Pacific Ocean from Alaska to Washington where there are cooler waters. 


Sperm Whale: 78 feet (24 meters) 

Its technical name is Physeter Macrocephalus and they are also known as cachalot. They are the largest-toothed predator in the world. Though their size is as biggest as an eight-floor building, they are rarely identified by their magnitude, but by their sounds. They use an impressive technique called echolocation to find their prey and communicate with other whales. Their calls are much stronger than the sound of a rifle shooting off right next to the ear (with up to 230 decibels underwater and 170 decibels on land).   


Whale Shark: 62 feet (18.8 meter) 

Its technical name is Rhincodon typus. It's also known as the biggest fish that swims in the ocean. However, this beautiful fish acts more like a whale than a shark. Their mouth can be open up to five feet wide and is filled with hundreds of small teeth. They use to eat plankton and some occasional fish taken by accident. They do not represent a threat to humans or other large animals.   


Basking Shark: 40 feet (12.27 meters) 

It is the second largest fish and shark in the ocean with a measure of over 40 feet, the equivalent of a school bus. It has an enormous snout that adds to its weight. Technically is also known as Cetorhinus maximus. Their impressive weight is about 8,500 on average, taking into account that they only eat plankton, larvae, and fish eggs.   


Giant Squid: 40 feet (12 meters) 

The Giant Squid is within the cephalopod family and its technical name is Architeuthis dux. They have massive tentacles that allow them to eat prey over 30 feet away from their position. These species are still surrounded by o lot of mystery since they live in the deepest waters and they had not been investigated in many scientific studies.   


Giant Pacific Octopus: 32 feet (9.8 meters) 

Is the largest marine cephalopod, with a radial spread of over 32 feet. They can cover the size of a modest home and it's hard to find them due to their ability to change color and camouflage when they feel threatened. They can be geographically located in the coastal areas of the United States, Canada, Mexico, Russia, Japan, Korea, and China.    


Oarfish: 26 feet (8 meters) 

The oarfish has been titled in different ways, however, the most remarkable one is the “ribbonfish”. That name obeys their unusual form, scale, and length. Some people also refer to them as dragons or ocean serpents. They usually live in dark water from the Atlantic, Mediterranean, and Pacific Seas, likewise in the Republic of Mauritius and the Bay of Bengal. The scientific information collected about them comes from the few that approach the shores.   

Japanese Spider Crab: 12 feet (3.7 meters) 

The Japanese Spider Crab is not only the largest crab in the world but the largest crustacean at the same time. Also is the largest invertebrate animal on land and water. They are known by their experience to camouflage (When young, they decorate their shells in a chance to hide from predators). When they become elder, they defend themselves using their large size and strong claws.   


Ocean Sunfish: 11 feet (3.3 meters) 

They are also known as Mola Mola fish or common Mola. It is the largest bony fish and the heaviest vertebrate in the world. They do not have a tail; however, they use their swimming head to navigate the ocean. Their movements have been considered fine and beautiful even when their weight may reach over 5,000 pounds.
