Oarfish only live in the deep, warm waters of the Pacific and Atlantic oceans. It is the longest oarfish in the world. Oars are carnivorous fish. They are ferocious and feed on any marine animals they can find, and they also exhibit cannibalistic behavior. After research, scientists believe that the ferocious behavior of oarfish comes from the scarcity of other fish and the lack of food in the deep waters where they live. They evolved over a long period of time to survive. This discovery once again confirms the eternal law of nature: “The weak eat the strong and the strong survive.”

After talking about the largest creatures in the ocean
Sanshajun will give you some popular science
Creatures that are on the verge of extinction in the ocean today
Otter
< p>OtterWhether she gives birth or sleeps
Almost everything is done underwater
Due to ocean pollution, otter liver is a valuable traditional Chinese medicine.
They were sought after by otter hunters, causing a sharp decline in otter numbers.
Dugongs
are mainly distributed in the western Pacific and Indian oceans.
They prefer maritime areas with good water quality and aquatic plants abundant.
Because meat is used to extract oil, bones cancan be carved into objects and the skin can be used to make leather
They have been hunted and killed by humans, and the number of dugongs has become extremely rare until now.
Leatherback turtles
The leatherback turtles we just mentioned are also among the endangered sea creatures.
Leatherback turtles are becoming more and more common due to the causes people to throw their plastic bags into the ocean. Skin turtles
Mistake them for jellyfish and eat them by mistake, causing intestinal obstruction and death
Coupled with overcatch and drowning, the number is decreasing day by day. day
Su Mei Fish
Su Meiyu is a famous delicacy because of its tender meat.
The high price encourages some people to catch Su Meiyu.
The population is continually decreasing and some areas have even disappeared.
Whale sharks
Whale sharks have almost nono natural enemies
Human fishing activities are the main reason for their decline.
Caught whale sharks mainly eat their meat.< /p>
Sometimes their fins are cut to make shark fins.
Blue Whale
As there is a thick layer of blubber under the skin of the blue whale,
it can be used to make soap, shoe polish, etc.
As a result, blue whales have been hunted in large numbers by whalers.
There are currently only 200 to 453 surviving blue whales, and they are on the brink of extinction.

Scientists have discovered more than 300 new species in the deep sea
According to the British "Guardian" report on June 17, from May to June 2017 In August, scientists traveled along the Australian coast towards the Coral Sea. They collected over 1,000 species of lifemarine in the seabed at a depth of 4,000 meters, including more than 300 new species.
The red coffin fish in the photo has blue eyes and a fluffy, soft “fishing rod” on its head. This fishing rod can attract prey to the bait. When threatened, it swells its body with water to appear more "powerful". This is the fish found this time in the deepest part of Australian waters.
It is a carnivorous crustacean that is a "scavenger" in the deep sea, eating anything that can provide nutrition, including rotting whale carcasses.
This is the fragile and bright star. It uses faint fluorescence to warn predators not to treat them as food.
The blobfish, also known as the sad fish, lives mainly in the Tasman Sea, between Australia and New Zealand. In 2013, the blobfishbeen nicknamed the ugliest fish in the world. It has no bones, no swim bladder and a gelatinous body, waiting for its prey to pass by and kill it with a surprise blow. .
This coral-like creature belongs to the same species as sea anemones, jellyfish, corals and other tentacled sea creatures. The difference is that it does not have the exoskeleton of his “parents”.
A group of sea pigs has been discovered in the Freycinet Marine Reserve on the island of Tasma. These little sea pigs are all pink on the seabed. They are adorable ocean vacuum cleaners, using their straw-like legs to clean. the mud in the depths of the sea. Move inside and absorb the microorganisms inside. It is the only species to have "feet." Sea cucumbers congregate in large numbers in areas where food is plentiful.
Tripod fish are representativesdeep sea fish. They use their long flippers to walk on the seafloor like stilts. They belong to the Lampeye family, and they have poor eyesight. It is a characteristic of the family when feeding, they stand against the current and extend their long pectoral fins forward to "feel" the prey drifting ahead. >Cigare Damour sharks have well-arranged serrated teeth. They are small and emit light in the "twilight zone" 1,000 meters deep in the ocean, they are known as large fish, whales, dolphins and even hapless creatures. swimmers, sometimes even destroying submarines or underwater cables, and once they locate their target, they bite off cookie-sized pieces of meat. This is the first time they have been spotted in Australian waters.
Red spiny crabs. are covered with bright red spines toensure that they are not in danger in the deep sea. These are not true crabs, but are closer to hermit crabs.
