On the earth, there is a kind of reproductive isolation between animal populations and populations, but there is a situation where even different populations can cultivate offspring.
According to news on July 14, China's first cetacean Full Moon, who has the dual bloodline of bottlenose dolphin and false killer whale , is now able to complete swimming, jumping out of the water and other actions on its own.
This is the first domestic cetacean successfully cultivated in Tianjin Haichang Polar Ocean Park on June 13th under artificial intervention! In just one month, the cetacean has been able to perform some very active actions in the water, attracting close attention from many people.
According to reports, there have been no cetaceans with artificial participation in our country before. This is a "new hybrid species" that can occasionally be seen in nature. Its body is slightly larger than that of bottlenose dolphin calves. , the skin is mainly inherited from the false killer whale and is black. The most typical feature of
is that the abdominal skin is gray-white like dolphin , while the head, snout and other areas are a mixture of false killer whales and dolphins.
According to foreign experts who have successfully conserved cetaceans, the most difficult period for this kind of artificial intervention is the lactation and newborn periods. In view of the fact that there has been no successful experience in cetacean conservation in China, now Tianjin Haichang Polar Region Ocean Park conservation staff have dedicated personnel taking care of it 24 hours a day.
Observe the status of mother and child cetaceans at any time. If there is an injury or other emergencies, they can respond immediately. At the same time, special arrangements have been made for areas in the museum, such as anti-collision, anti-irritation, etc.
However, this kind of artificial conservation behavior has also been questioned on the Internet. Some netizens said: These are two different animals. Why is there no reproductive isolation? Even if human intervention is in line with some biological order?
In fact, many friends may not know it well. false killer whale and killer whale both belong to the Delphinidae family. They are also one of the largest species in the Delphinidae family, so they belong to the same category.
Also, the premise of reproductive isolation is that the isolation mechanism will be adopted between taxa that are closely related, or if they cannot produce offspring or cannot produce fertile offspring even if they can mate.
So should human intervention be necessary? In fact, in the natural environment, such hybrids also exist. In other words, cetaceans are not artificial products in the first place, and many cases have been discovered in the ocean.
therefore does this without much problem. On the contrary, this successful artificial conservation has increased my country's experience in cetacean conservation.
Finally, the staff also said that after the cetaceans stabilize in the future, they will be open to the public for everyone to watch. So the question is, will you run over and take a look?
