The cold wave is coming, the temperature in Shencheng has plummeted, and everyone is wrapped in three layers inside and three layers outside when they go out~ In such a low temperature weather, how do marine animals survive the winter safely?
At the time of Xiaobu's interview, the outdoor temperature in Shanghai Haichang Ocean Park was as low as -3°C, while in the Sea Beast Exploration Museum, some of the sea lions and seals were swimming happily in the water, and some were gathered on the shore in groups of three or five to sunbathe. "It may feel very cold for us, but for marine animals such as sea lions and seals, they feel very comfortable, their daily lives are not affected in the slightest, and they are still doing their normal activities every day, swimming in the water and even going ashore to blow this cold snap. Zhang Yang, a sea lion seal keeper, said with a smile.
In the Killer Whale Aquarium, the killer whales are exercising in the company of conservationists, sometimes jumping, sometimes diving, sometimes spinning in circles, full of vitality. Chen Jie, senior conservationist of killer whales, introduced that in nature, many marine animals have the Xi of living in groups, diving deeply, and migrating to warm waters in winter. To this end, the zoo not only provides a heated pool suitable for different marine animals, but also allows them to exercise properly to ensure that they survive the winter. Chen Jie said: "The water temperature of our dolphin babies is kept at 18°C~21°C all year round, and the water temperature in the killer whale aquarium is kept at 13°C~16°C all year round. ”
Xiaobu saw that every once in a while, the keepers would feed the killer whales ice cubes. "Ice cubes are mainly used to replenish fresh water in the animal's body. Marine animals live in the sea, in fact, seawater is not drinkable, and it cannot be used to replenish fresh water in the animal's body. The fresh water in the animal's body is extracted from their bait and ice, and the largest killer whale in the museum, the Fat Tiger, for example, now eats 12 buckets of ice every day, totaling about 160 catties of ice. Chen Jie introduced.
In addition, every winter, the conservationists will also add 30% of the food to the marine animal science, and physically protect against the cold by raising fat.
