Shrinking whales
With the help of drone technology, scientists can also measure whalefish carcasses. This suggests that some animals are actually declining, which scientists have linked to climate change affecting their food supply. A study published in the journal Global Change Biology also found that winter whales that feed in the shallow waters off the Pacific Northwest coast have shrunk significantly over the past two decades. Another observation in the same context is that a gray whale born in 2020 is expected to be 1. 65 meters shorter than the adult body length of a preborn winter whale. According to the researchers, this is an alarming sign that the population is starting to decline. In addition to helping researchers monitor emerging threats to whales, the drones also shed light on the behavior of some interesting marine species. One of these includes the observation that we are working together to feed the beavers seen in Antarctica, which gives us an insight into how whales learn and interact with each other. The researchers observed in important humpback whales that one animal usually blows a bubble around the prey, and the other animals have individual roles. But in Antarctica, we often see more than one animal in the feeding ground blowing bubbles. Researchers are still mulling over what this activity might mean, but some suspect that Antarctic whales may still be learning feeding techniques and that they have just given each animal that role. Nothing better than that. Dr Friedlaender said, “What can we think about the behavior we’ve seen in humpbacks?” As humpbacks move around our boat and even interact with other species, whether it’s performing the activity as a game or naturally. It is a habit for them to be curious about new things, to make connections with them, and to interact with other species. Or it may be that these activities strengthen their social bonds and that all of these activities are of great value to them.FAQs
Humpback whales have the longest and most complex songs in the marine animal kingdom, according to research so far. Along with this, he is also famous for acrobatics.
Males
Although all species of humpback, males and females, may produce different vocalizations, according to the latest research, only males sing, and their songs are often heard on their breeding grounds.
According to research, whales sleep with half of their brain shut down to relax while the other half stays awake. This may be because sea creatures have evolved to breathe voluntarily as air-breathing creatures, which means they can consciously breathe.
Although whale eyes have few cones, they contain many rods. The function of cones is to capture color, while rods allow an animal to see better in low light. Whales, therefore, have prioritized night vision over color vision.
