I don’t know if you remember a killer whale called J35?
In July 2018, the killer whale mother gave birth to a killer whale baby, but the baby died only half an hour after birth.
The sad killer whale mother pushed her child on her head, and did not want to let the baby’s body fall to the bottom of the sea.
In the next two weeks, the killer whale mother still refused to give up her baby.
It swims for 17 days with the child’s body, a distance of thousands of kilometers.
Even if the body of the killer whale began to rot, it insisted on putting the body on his back.
The story of J35 has moved the world by its great motherly love. However, in addition to being moved, this story also reminds humans that the fate of the killer whale is already on the edge of the cliff.
Killer whale is an animal of a group. The J35 belongs to a ethnic group called the southern resident whale (southern resident whale).
This killer whale group lives in North America. In the 1970s, there were only more than 90 left. Now there are only 74 whales left, which is extremely endangered.
The killer whale is located at the top of the food chain and has no natural enemies in nature.
But at the same time, their abortion rate and baby’s mortality are very high. Basically, each two killer whales are born, and only one can survive to grow up smoothly.
In addition to the internal causes of fertility, human activities have also greatly affected the survival of this group of killer whales.
Because the dietary habits of this group of whales in the south are different from other killer whales,
Most killer whales are extremely rich in recipes. From small fish to sea lion seals and other mammals, to whales, and even some seabirds, they are the targets of killer whales.
However, these southern resident whales are not the case. 97%of their foods are local salmon.
Over the years, due to the pollution of seawater, human fishing has led to the decline in the number of salmon.
What is even more troublesome is that more and more busy human routes also affect the survival of killer whales.
The killer whale communicates and hunt through the echo positioning system, but more and more noise from the boat brings more and more serious physical and acoustic interference to the killer whale.
Scientists describe that the noise on these ships seems to have imposed a penalty of thousands of knives and thousands of stuns …
Because of the above reasons, the population of the southern whales has reached a precarious level.
Fortunately, during the epidemic, these killer whales finally waited for hope.
Recently, a group of scientists discovered that there were three anti -halberd whales in this group.
Three of the pregnancy are J35 relatives, J19, J36, and J37.
(J36 "Xianhuai")
In fact, in 2020, the J35 was pregnant again, and he gave birth to a baby whale baby and was named J57.
Coupled with this year, scientists also discovered three pregnant whales at the same time, 4 babies in two years, so that scientists feel that the cub whale is expected to revitalize …
More importantly, not only the killer whale population in North America saw hope, the Australian humpback whale group also appeared rare wonders.
On the sapphire coast in Australia, some scientists have discovered a huge group of about 150 head whales.
This is a very rare phenomenon, because in human cognition, humpback whales are a very lonely creature, and usually less than 15 whales can be accommodated in a group.
But this time, people discovered that more than a hundred humpback whales not only lived together, but also hunted together.
They will gather together, sneak into the depths of the ocean, and blow out the bubbles from the pores above their heads, blow out the fish above them, and they can be rushed.
In fact, in the history of Australia, people have only seen two such large -scale humpbacks.
One time this year, and the other last year …
For this special situation, scientists explain, saying that
It is because during the epidemic, there are finally no cruise ships or other water traffic on this sea …
In fact, if you think about it, this is also a ironic,
When people come to the sea by boat, while admiring these beautiful animals with mercy, they are actually pushing them to despair …
I also hope that after the epidemic, more countries can learn lessons and use more comprehensive laws to protect these gentle giants in the ocean …
