Research has said that these marine mammals used to grow up to an average of 46 feet i.e. 14 meters, but now the new generation is growing up to 43 feet i.e. 13 feet on average.
The size of a giant creature present in the depths of the water is gradually getting smaller. These results have come out in recent research. The size of the new generation of the critically endangered North Atlantic Right Whale has been found to be about three feet smaller than the previous right whale.
This information was given in the study conducted on the basis of drones and aircraft in the journal Current Biology on Thursday. Scientists say that humans should be to blame for this. The study said that due to constant entanglement with fishing equipment, ships and climate change, their food supply is being affected and pressure on right whales is increasing.
Length reduced to 1 meter
The study said that the reduction in size is a threat to the survival of the entire species because whales do not have many babies. The authors of the research said that they are not old enough to breastfeed their children or become pregnant. Research has said that these marine mammals used to grow up to an average of 46 feet i.e. 14 meters, but now the new generation is growing up to 43 feet i.e. 13 feet on average.
Regina Asmutis-Sylvia, executive director of Whale and Dolphin Conservation North America, said it was chest pain before a heart attack. Ignoring it would lead to a tragedy. He said that the solution or treatment of this problem can save the entire species.
Only 356 whales survived
Study co-author Amy Knowlton, a senior scientist at the New England Aquarium, said there are now only 356 North Atlantic right whales left, compared to 500 in 2010. Although according to other estimates, their population is 400, but researchers believe that their population is decreasing.
This problem came up many years ago during a research trip. Knowlton and others had seen some small whales and a dead whale. Based on the size, they thought the life of the small whale would be less than a year, while investigations found that the whale’s life is actually about two years.
