Hibbs2*, Nicholas W. Bellono1* Sensory systems for mate recognition maintain species boundaries and influence diversification. Thus, uncovering how molecules and receptors evolve to mediate this critical function is essential to understanding biodiversity. Male octopuses use a specialized arm called the hectocotylus to identify females and navigate their internal organs to reach the oviduct and deliver sperm. Here, we discovered that the hectocotylus is a dual sensory and mating organ that uses contact-dependent chemosensation of progesterone, a conserved ovarian hormone. …
