Blue whales' mysterious silence leave scientists worried as it sends a dire warning to humanity
Alarming reports indicate a significant decline in blue whale vocalizations due to devastating heatwaves. These heatwaves have triggered toxic algae blooms, disrupting the whales' food sources like krill and anchovy. Researchers observed a nearly 40% drop in whale song, coinciding with a massive marine heatwave known as "The Blob. Scientists have raised an alarm over the ghostly silence of blue whales.
The heatwave reduced the food whales rely on and triggered harmful changes in ocean chemistry, allowing toxic algae to bloom
Scientists have raised alarms after noticing a significant drop in the in the number of vocalizations from blue whales. Scientists have used specialized underwater hydrophones (aquatic version of microphones) to record and trace the sounds of marine life and noticed a significant drop in whale calls. These recordings help scientists track marine life and understand how human activity affects different species.
According to the details published in the journal PLOS One, devastating heat waves have triggered worrying changes over the past decade, allowing toxic algae to bloom and undermine food sources for whales. The heatwaves have disrupted the whales' environment, causing a chain reaction in the ocean's food web.

These were hard times for whales,” John Ryan, a biological oceanographer at the Monterey Bay Aquarium Research Institute, told National Geographic.

Are blue whales going silent?In a study published earlier this year, which traced more than six years of acoustic monitoring in the central California Current Ecosystem, Ryan and a team of researchers found clear patterns in whale song across seasons and years. By chance, the recordings began during a massive marine heatwave unlike anything seen before in the region.
