Researchers record baby humpback whales 'whispering' to their mothers
Revealing a previously unknown survival technique of whales, a new study found that newborn humpbacks and their mothers whisper to each other to escape potential predators.
The recordings of the whispers in the form of the infant whales’ quiet grunts and squeaks were made with devices attached to the baby whales, which are typically nearly 5 meters long at the time of their birth.
During an annual migration to food-rich waters of the Antarctic region, newborn whales have to travel with their mothers for thousands of miles. Exactly what occurs during this period is still a mystery.
Simone Videsen from Denmark’s Aarhus University said, “These early life stages of wild whales are so elusive because they're an aquatic animal. We can't follow them around all the time to see what they're doing.”
The new study suggested that the baby humpbacks whisper in really low sounds because they do not want any unwanted listeners, such as killer whales which can predate on these calves.
The discovery of the existence of the previously unknown survival technique of the humpback whales was detailed in the most recent edition of the journal Functional Ecology.
