In their groundbreaking study, the Norwegian researchers found that comb jellies can undergo 'reverse development' similar to the 'immortal jellyfish', allowing them to revert to an earlier life stage when encountering stressors. This unexpected discovery highlights the resilience of these marine species and challenges the traditional understanding of jellyfish life cycles, suggesting that stress responses may be widespread among various jellyfish-like organisms.
'Immortal' is a bit of a misleading term. 'Reverse development' is more correct,' said Pawel Burkhardt, emphasizing the importance of accurately describing the process. Yet, the study's findings demonstrate a significant evolutionary adaptation in marine species, allowing them to survive and thrive under adverse conditions whether through starvation or physical trauma. This research raises questions about how many other species may exhibit similar abilities.
Using methods such as lobectomy and starvation, the researchers observed a 40% reversion success rate in comb jellies, revealing a fascinating survival strategy that may redefine our understanding of marine life adaptability. Joan Soto-Angel's meticulous experimentation illustrates how stress can trigger profound biological responses, offering insights into the resilience of marine species and the potential implications for environmental changes.
