Abstrakt: A recent study published in the journal Australian Mammalogy has documented the rare phenomenon of cannibalism among antechinus, a native marsupial found in Australia. Antechinuses are known for their semelparity, or "suicidal reproduction," where males die after a breeding season. The stress hormone cortisol and surging testosterone during mating cause organ failure and death in males. The study suggests that living antechinuses may take advantage of the cheap energy boost provided by consuming the carcasses of dead males. This behavior may also occur between different antechinus species. [Extracted from the article]
