National Geographic reports a serious concern among scientists regarding blue whales having virtually ceased their characteristic «songs.» This alarming trend points to potential threats to these magnificent marine creatures and the wider ocean environment.
According to published data, a recent study revealed a nearly 40% decrease in the vocalization intensity of these marine giants.
The publication attributes this phenomenon to the impact of marine heatwaves, which are causing ocean temperatures to rise. This, in turn, has led to a catastrophic decline in the krill population – the primary food source for blue whales.
Oceanographic biologist John Ryan from the Monterey Bay Aquarium Research Institute metaphorically described the situation, stating it`s «like trying to sing when you`re starving to death.»
Oceanographer Kelly Benoit-Bird added that a prolonged food shortage for whales will inevitably lead to serious negative consequences for the entire marine ecosystem, potentially disrupting delicate balances critical for ocean health.
The blue whale (Balaenoptera musculus), a member of the Balaenopteridae family and the baleen whale suborder, is the largest animal to have ever lived on Earth. These incredible creatures can reach a staggering mass of up to 150 tons and lengths of up to 33 meters, making their diminishing vocalizations a significant indicator of environmental stress.
