Why These Moths Don't Run Away from Bats

The video discusses two studies: one on how animals, like tiger moths, use chemical defenses to stay calm under predator attacks, and another on how soil bacteria contribute to breaking down bedrock to release nutrients. The first study reveals that less palatable moths are more relaxed when attacked, suggesting chemical traits can predict animal behavior. The second study shows that chemolithotrophic bacteria can break down rocks, providing essential minerals for soil, highlighting their importance in the ecosystem.
