P.S.Villar et al. (2026) studied #evolutionary aspects of the #copulatoryorgan in #male #octopuses and describe it as #multifunctional organ that performs two key #functions: the #hectocotylus is a specialized tentacle that delivers #spermatophores into the #female's #mantlecavity. But the authors identified it also as #chemotactile #receptor for #progesterone during #materecognition.

MALE OCTOPUS REPRODUCTIVE HABITS RAISE QUESTIONS ABOUT SPECIALIZED ARM USAGE

Male octopuses use a special arm called the hectocotylus for sperm delivery. This arm usage affects their survival after mating.

Male octopuses use a unique arm, the hectocotylus, for mating. This specialized limb is key for sperm transfer and can impact the male's lifespan.
