Summary:
- Otter poop, or "spraint," can provide valuable insights into the role otters play in controlling parasites in their ecosystem.
- Researchers analyzed otter spraint and found it contained high levels of a parasite that infects fish, suggesting otters help regulate the spread of this parasite by consuming infected fish.
- The study highlights how studying animal waste can give scientists a better understanding of the complex relationships between predators, prey, and the parasites that affect them in the natural world.
