/magazine/html/137/137389.htm (the largest marine life-blue whale)
The following is irrelevant, but there is no harm in taking a look ... (I may want to study it myself after reading it, hehe)
Look at this:
The king squid is about 20 meters long, but there may be a bigger king squid in the deep sea. It is speculated that the largest king squid is 60 meters. So if the king squid is really 60 meters, then the king squid is the largest marine animal.
The king squid lives in the deep waters of the Pacific Ocean and the Atlantic Ocean. It is about 20 meters long and weighs about 2-3 tons. It is the largest retarded vertebrate in the world. Its temperament is extremely fierce, it feeds on fish and invertebrates, and it can fight with giant whales. It is often reported abroad that the king squid fights with the sperm whale. According to records, once a king squid was witnessed holding a sperm whale tightly with its thick horn hand and sucker, and the sperm whale tried its best to bite the tail of the king squid. Two behemoths in the sea rolled violently, stirring up turbid waves, and then both sank to the bottom of the water, not knowing where to go. Most of this kind of struggle is that sperm whales win, but there have also been cases where the king squid strangles whales by holding their nostrils with their hands.
From this point of view, the sea monsters encountered by people in the two years mentioned above, 186 1 and 1878, are definitely king squid. How big is the biggest king squid? This question is difficult to answer. People once measured a squid with a length of 17.07 meters, and the diameter of the sucker on its horn was 9.5 cm. However, from the captured sperm whale, a sucker scar with a diameter of more than 40 cm was found.
It is speculated that the king squid fighting with this whale may be more than 60 meters long. If there is such a big king squid, it is not far from the legendary Norwegian sea monster.
At present, the largest known marine animal is the blue whale, and all the information is on it.
As for the largest marine life, it should be giant algae.
Macroalgae belong to brown algae, which is the longest group in the algae world. Most of the giant algae can grow to tens of meters, and the longest can even reach 200 to 300 meters, weighing 200 kilograms. The algae body is fixed on the reef by a fixer with a length exceeding 1 m. The center of the macroalgae is the trunk, with more than 65,438+000 branched petioles with small leaves, some of which are more than 65,438+0 meters long and 6 cm wide to 65,438+07 cm. There are air bags on the leaves, which can generate enough buoyancy to lift the leaves or even the whole algae. These airbags are regularly arranged on both sides of the main vein on the blade. In places where giant algae flourish, huge leaves can cover hundreds of square kilometers of sea surface layer by layer. Giant algae is one of the fastest growing plants in the world. Under suitable conditions, each giant seaweed can grow 30 to 60 centimeters a day. Within a year, a giant seaweed can grow to more than 50 meters. Giant algae growing in the tropics grow all year round, and fishermen who collect giant algae at the seaside can harvest them three or four times a year. The life span of giant algae is generally between 4 and 8 years. The longest-lived macroalgae can grow for 12 years. If you plant 1000 macroalgae per hectare of sea surface, you can harvest 750 ~ 1200 tons of fresh macroalgae every year. Giant algae are native to the Atlantic coast of North America and distributed in the coasts of Australia, New Zealand, Peru, Chile and South Africa. China scientists introduced the giant algae from Mexico to China in 1978. At present, the cultivation of giant algae has been successful in the coastal areas of China. Since then, algae in mariculture in China has added a new force.
