After talking about the largest creatures in the ocean
Sanshajun will give you a little popular science
The creationsatures that are about to disappear in the ocean today
Otter
< p>OtterWhether she is giving birth or sleeping
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 the meat is used to extract oil, the bones can be carved into objects and the skin can be used to make leather
They were hunted and killed by humans, and the number of dugongs has become extremely rare until now.
Leatherback turtle
The leatherback turtle that we have just mentioned is also one of the marine creatures inendangered
Because people in the oceanDisposing of plastic bag waste has caused leatherback turtles
to mistake them for jellyfish and eat them, causing intestinal obstruction and death
Coupled with overcatch and drowning, the number decreases

Su Meiyu
Su Meiyu has a fresh and tender meat and is a famous delicacy.
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 no natural enemies
Human fishing activities are the main reason for their decline.
p>
Captured whale sharks mainly eat their meat.
Sometimes their fins are cut off to make shark fins.
Blue whale
As there is a thick layer of blubber under the skin of the blue whale,
it can bebe 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 more than 1,000 species of marine life from the seabed 4,000 meters deep, 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". It is the fish that we finde 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 blobfish was dubbed 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. .

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. They are the only sea cucumbers with “legs” and are found in large gatherings where food is plentiful.
Tripod fish are representatives of deep-sea fish. They use their long.The fins of the fish look like stilts on the bottom of the sea. They belong to the family of the genus Lampidae.

This is the first time they have been spotted in Australian waters.
Red spiny crabs are covered in bright red spines, which ensures that they will not encounter any danger in the deep sea. They are not really crabs, but rather hermit crabs.
