Why some animals die after mating: Male antechinus, praying mantis, octopuses and more
Some animals reproduce only once before dying. This life strategy, called semelparity, sees organisms channel all energy into reproduction. Mechanisms include stress hormone overload, sexual cannibalism, and abstinence from food. Species like male antechinus, lamprey, redback spiders, praying mantids, octopuses, and adult mayflies exhibit this phenomenon. Their bodies are organized for a single reproductive event.
