My name is Blue Whale and I am a marine mammal belonging to the suborder Baleen whale.
I am considered the largest known living animal on Earth, up to 33 meters long and weighing 181 tons, feeding mainly on small crustaceans (such as krill) and small fish.
My strength is amazing, the power emitted is about 1500-1700 horsepower, which is the well-deserved giant and Hercules in the animal world.
The confluence of warm and icy waters is our perfect habitat, and we are found in all four oceans.
We usually like to use our tail fins to draw water, which is a pastime with many uses and multiple purposes, either to make games or to attract the attention of our companions.
My name is Chinese sturgeon and it is found in China, Japan, Korea, Laos and North Korea.
My average body length is about 40 cm, the longest is 130 cm, and the maximum weight is 600 kg.
Our body is spindle-shaped, the tip of the head is long, there are 4 snouts in front of the mouth, the mouth is located on the ventral surface, it is elastic, and it can be stretched into a cylinder, and the body is covered with five large and hard bone scales, one row on the back, two rows on the side of the body and two rows on the ventral side.
We mostly live in large rivers and offshore waters, are demersal fish, and are migratory or semi-migratory.
My life cycle is long, the longest life expectancy can reach 40 years old, is China's first-class key protected wild animals, but also a living fossil, known as "giant panda in the water"!
My name is octopus, and it is widely distributed in the tropical and temperate waters of the world's oceans.
Our body is short oval, cystic, without fins; the boundary between the head and the body is not obvious, the head carcass is about 7-9.5 cm, and there are large compound eyes and 8 retractable wrists on the head.
I am a temperate mollusk, living underwater, adapting to water temperatures not lower than 7 °C, and the proportion of seawater 1.021 is the most suitable.
I am a carnivore and feed on flap gills and crustaceans (shrimp, crabs, etc.).
Not only could I spray ink six times in a row, but like the most agile chameleon, I could change its color and structure like a stone covered with algae, and then suddenly pounce on the prey, which had no time to realize what was happening.
