Merged summary

TL;DR - Researchers identified a transmissible melanoma spreading among catfish in a freshwater lake. The finding raises questions about how the cancer emerged, how it passes between fish, and its potential impact on the species.

  • The cancer can spread between individual catfish rather than arising independently in each animal.
  • It represents a transmissible melanoma in a freshwater environment.
  • Its origin and transmission mechanism remain unresolved.
  • The available summary does not provide prevalence, molecular, or ecological-impact data.
