8. King Soup Squid

King Physalis is a typical deep-sea giant squid and the largest invertebrate in the world. It is heavier than the king squid, mainly distributed in the waters around the Antarctic continent, occasionally distributed in the north of the South African coast, and most of them inhabit the deep sea of about 2000 meters in the Antarctic waters.

9. Black whale

It is one of the top ten fish in the world, mainly feeding on planktonic invertebrates, small fish or fish eggs, and distributed in the northwest Pacific Ocean, southern Australia and other sea areas.

What is the biggest animal in the ocean? The biggest animal within 2 nautical miles is the blue whale.

The blue whale is considered to be the largest known animal on earth, with a body length of 33 meters and a weight of 18 1 ton. The blue whale has a slender body and a blue-gray back, but sometimes it looks lighter in water.

Like other baleen whales, blue whales mainly feed on small crustaceans (such as krill) and small fish, sometimes including squid. Usually, blue whales need to feed in the sea above 100 meters during the day, and they can only feed on the water at night.

Blue whales begin mating in late autumn and continue until the end of winter. Female whales usually give birth every 2-3 years. After 10- 12 months of pregnancy, young whales are usually given birth in early winter. The four oceans are distributed.

Extended data

The blue whale is not only the largest whale, but also the largest living animal and the largest mammal to date. Generally, it is 2200-3300 cm long and weighs150,000-180,000 kg. In other words, its weight is equivalent to more than 25 African elephants, or the sum of the weights of 2000-3000 people.

Fortunately, because of the buoyancy of the ocean, it doesn't need to support its weight as hard as land animals, and its huge body helps to keep a constant body temperature. The whole body surface of the blue whale is light blue or mouse gray, with thin stripes on the back, white spots on the chest and more than 20 folds, and the abdomen is covered with folds all the way to the navel with ochre spots.

Female animals have milk and grooves on both sides of reproductive pores, and slender nipples inside. The head is small and flat, with two spray holes on the top of the head, a wide mouth, no teeth in the mouth and a wide upper jaw. It bulges upward in an arc shape, with 300-400 black whiskers on each side, 90-110cm long and 50-60cm wide. A large amount of earwax accumulates in the eardrum every year, and its age can be judged according to its thickness.

It also has a white callus on its upper jaw, which used to be a place for long hair. Later, the hair degenerated, leaving a warty vegetation and becoming a breeding ground for parasites. Because this callus is different for each individual, just like wearing a hat with a different shape, different individuals can be distinguished accordingly.

The dorsal fin is extremely short, the length is less than 0.5% of the body length of 65438+, and the flipper limb is not too long, about 4 meters, with four toes, no wavy notch at the back edge, and a wide and flat tail. The whole body is streamlined and looks like a razor, so it is also called "razor whale".

What is the biggest animal in the ocean? 3 1. The largest marine life in the world is the blue whale.

2. The blue whale is a marine mammal, belonging to the suborder baleen whales.

* * * There are four subspecies. The blue whale is considered to be the largest known animal on earth, with a body length of 33 meters and a weight of 18 1 ton. The blue whale has a slender body and a blue-gray back, but sometimes it looks lighter in water.

Like other baleen whales, blue whales mainly feed on small crustaceans (such as krill) and small fish, sometimes including squid. Usually, blue whales need to feed in the sea above 100 meters during the day, and they can only feed on the water at night. Blue whales begin mating in late autumn and continue until the end of winter. Female whales usually give birth every 2-3 years. After 10- 12 months of pregnancy, young whales are usually given birth in early winter. The four oceans are distributed.

3. Human settlements

The intersection of warm water and cold water is an excellent habitat for blue whales. Cold sea water is usually rich in plankton and krill, which are usually eaten by blue whales. Blue whales are distributed all over the world, with the largest number in Antarctic waters, mainly distributed in temperate and cold seas with water temperature of 5-20℃. Some whales swam in the Yellow Sea and the waters of Taiwan Province Province.

4. food

Most of the bays inhabited by blue whales are flooded with extremely rich organic matter in the river water on the landing land, which makes the water quality very fertile and promotes the massive reproduction of plankton. The dense plankton attracted a large group of krill, and their bodies shone blue like diamonds. The stomach of a blue whale is divided into four parts. The first stomach is caused by partial dilatation of the esophagus, so the appetite is very large. It can swallow about 2 million krill at a time and eat 4000-8000 kilograms every day. If the food in your stomach is less than 2000 kilograms, you will feel hungry.

Krill is the most abundant animal in the world, widely distributed in the Arctic and Antarctic waters. It is because there is such a rich food and there is no limit to support weight that blue whales can develop so much.

Every day, it spends most of its time swimming in dense plankton. The two rows of plate-like tentacles on its mouth are like a sieve, and its belly has many folds like accordion bellows, which can be expanded and contracted, so that it can swallow seawater and krill together, and then when its mouth is closed, seawater is discharged from the tentacles, filtering out shrimp and fish and swallowing them.

Blue whales eat other shrimps, small fish, jellyfish, diatoms and various plankton. In contrast, blue whales living in northern waters are smaller than those living in waters near Antarctica, which is generally believed to be related to their food types.
