In her book "Packing for Mars: The Curious Science of Life in the Void," Mary Roach explores various scientific topics related to space travel, including biological adaptations. She draws a unique and provocative comparison to illustrate the adaptability and resilience of certain organisms, such as the hydromedusa tectifera, which thrive in the waters of South America.

Roach’s analogy likens the hydromedusa tectifera to post-war Nazis, emphasizing their native origins in regions like Argentina, Paraguay, and Brazil. This controversial statement highlights how both have survived under challenging circumstances and adapted to new environments, prompting reflection on the nature of survival and resilience in both biology and history.
