Naked mole rats, known for their unique characteristics, live primarily underground and exhibit eusocial behavior similar to that of ants and bees. In a colony, only one female, the queen, breeds. A study conducted by scientists at the Max Delbrück Center for Molecular Medicine in Berlin has uncovered that naked mole-rat queens suppress the breeding of other females through a sophisticated olfactory signaling system rather than through aggression. Gary Lewin, a neurobiologist and senior author of the study, noted that naked mole rats possess a high number of olfactory receptor genes, which enhances their sense of smell, a crucial adaptation for navigating their dark underground environments.

Research Reveals Chemical Signals Used by Naked Mole-Rat Queens to Suppress Rival Fertility
A study from the Max Delbrück Center for Molecular Medicine has found that naked mole-rat queens use chemical signals to prevent other females in their colonies from breeding. This discovery highlights the importance of olfactory communication in these eusocial animals, which rely heavily on their sense of smell for navigation and social interaction.
