Episode notes
Commensalism Defined
- Commensalism, unlike symbiosis or parasitism, involves one organism benefiting while the other remains unaffected.
- It's a more selfish, one-sided form of cooperation in nature.
Owls and Blind Snakes
- Eastern screech owls bring blind snakes to their nests as food, but some snakes escape and live in the nest walls.
- These snakes eat parasites, benefiting the owls, while the snakes simply pursue their own survival.
Commensalism's Fuzzy Boundaries
- Ecologists struggle to define commensalism and categorize it into inquilinism, metabiosis, and phoresy.
- Josh expresses skepticism, arguing many examples fit other relationships like symbiosis or parasitism.
