Semelparity is close to a rule among octopuses: one clutch, a brooding fast, then death. Octopus chierchiae is a documented exception. Arcadio Rodaniche reported repeated spawning in the species in 1984, and laboratory culture has since confirmed it: females produce several clutches in succession, continuing to eat between them and living well past a first reproductive event.
The name needs care. O. chierchiae is the lesser Pacific striped octopus. The beak-to-beak mating posture and the tolerance of close neighbours often reported alongside it belong to a separate, still undescribed animal, the larger Pacific striped octopus, studied in aquaria by Roy Caldwell, Richard Ross, Christine Huffard and Rodaniche and published in 2015. The two are easily conflated; only the smaller one carries a scientific name.
Care is needed with how far any of this extends. Most detail comes from captive animals, and wild behaviour is thinly documented; captivity can alter both social tolerance and reproductive scheduling. What is solid is that at least one octopus lineage escapes the single-clutch pattern.
