Whale Songs Dim: Ocean Heatwave Silences Blue Whales

Imagine whales singing in the ocean like they're singing songs.

Scientists listened to these songs and noticed that blue and fin whales weren't singing as much.

This is because a huge heatwave warmed the ocean, causing a food shortage for the whales.

The whales primarily eat tiny creatures called krill, but the heat killed off many of them.

The whales were hungry and had to spend all their time looking for food instead of singing.

Scientists are worried because these changes could mean big problems for the ocean and its animals.
