Female secondary sex characteristics include: Enlargement of breasts and erection of nipples. [1] [2] Growth of body hair, most prominently underarm and pubic hair. [4] [1] [2] Widening of hips; [1] [2] lower waist to hip ratio than adult males. [20] Upper arms approximately 2 cm longer, on average, for a given height. [21]
In argonauts, the male transfers the spermatophores to the female by putting its hectocotylus into a cavity in the mantle of the female, called the pallial cavity. This is the only contact the male and female have with each other during copulation, and it can be at a distance. During copulation, the hectocotylus breaks off from the male.
The female-biased sexual size dimorphism observed in many taxa evolved despite intense male-male competition for mates. [28] In Osmia rufa, for example, the female is larger/broader than males, with males being 8–10 mm in size and females being 10–12 mm in size. [29] In the hackberry emperor females are similarly larger than males. [30]

Males have relatively more of a type of hair called terminal hair, especially on the face, chest, abdomen and back. Females have more vellus hair, which is thinner, shorter, and lighter, and therefore less visible. [46] Although males grow hair faster than females, baldness is more prevalent in males than in females.
Instead, the most anterior portion ends in a funnel-shaped structure called the infundibulum, which collects eggs as they are released by the ovary into the body cavity. The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity.
Female penetration of males is known in a few species, such as seahorse, but only Neotrogla females have a well-defined organ that can be described as a penis. [3] Likewise, reversal of sex roles has been recorded in a few other species of animals. Neotrogla, however, appears to be unique in having both traits. [2]
