The Struggle

Biological Parallel

Semelparous species — Pacific salmon, antechinus marsupials, most octopus species — execute a single reproductive event and die. The strategy involves terminal investment: redirecting all physiological resources toward reproduction by cannibalizing muscle, shutting down immune function, and accepting certain death. Sockeye salmon swim 1,300 km without eating while their bodies deteriorate. Male antechinus mate until their organs hemorrhage. Deep-sea octopuses brood eggs for years without feeding. The pattern: maximum investment with a bounded timeline and a specific delivery.
