Goldfish Pheromones: An Accidental Discovery
- Goldfish pheromones were discovered accidentally when male goldfish downstream from hormonally-treated females became excited.
- This suggests pheromones can evolve from eavesdropping, with males developing sensitivity to leaked cues, later becoming intentional signals.
Royal Jelly's Direct Tissue Impact
- Royal jelly, given to developing bee larvae, acts directly on tissues, not through typical sense organs.
- This "allohormone pheromone" influences development, demonstrating pheromones' diverse mechanisms.
Bolas Spider's Deceptive Pheromones
- Bolas spiders deceive male moths by mimicking female moth pheromones.
- They even adjust their counterfeit blends throughout the night to lure different moth species, showcasing pheromonal deception.
