“I was really shocked and shocked when I nodded,” said Sayaka Mitoh, PhD candidate at Nara University. He said, “I expected him to die quickly without heart and other vital organs.”
Apart from surviving, the animal regenerated its body and all its vital organs in just three weeks. Which raised a question in the mind of Mitoh and his team: how and why did these slaves kill themselves?
Answer may be parasitic
In a study published in the Scientific Journal last Monday (8) Current biology. Both Alicia Marginetta and her cousin, Alicia Atroviridis, have the same ability and intentional beheading to get rid of them. Parasite Those who infect their bodies.
To arrive at this conclusion, researchers looked at both species from birth to death. While some individuals have not been beheaded once, others have performed the procedure twice.
In both species, the body subsequently regenerated from the head, but the bodies did not form a new head, although they continued to respond to stimuli for some time before they began to disintegrate.
