Exempel på hur man kan använda HEMIPENIS i en mening

• Rhacodactylus geckos are sexually dimorphic, with the males possessing larger preanal pores than the females as well as a distinct hemipenis pocket.
• While similar externally and ecologically, Podarcis form a distinct group differing from Lacerta by the construction of the skull and the hemipenis, and by the processes of the caudal vertebrae.
• A hemipenis (: hemipenes) is one of a pair of intromittent organs of male squamates (snakes and lizards).
• Craspedocephalus macrolepis has a long spineless hemipenis without papillae; the hemipenis has a long calyculate region beginning at some distance from the fork of the hemipenis and continuing until the tip.
• Postcloacal or hemipenial bones are also known, which are part of the hemipenis in male individuals.
• In 1975, American herpetologist Samuel Booker McDowell divided the genus Python into a "molurus group" and "reticulatus group" on the basis of differences in supralabial pits (shallow diagonal slits in the latter, square or triangular in the former) and infralabial pits (shallow and not in a groove in the former, in a groove in the latter), as well as differences in the ectopterygoid and hemipenis.
• Internal fertilization with many vertebrates (such as all reptiles, some fish, and most birds) occurs via cloacal copulation, known as cloacal kiss (see also hemipenis), while most mammals copulate vaginally, and many basal vertebrates reproduce sexually with external fertilization.
• Despite being partially digested, the specimen still displayed many unique traits, including undivided subcaudals for the full length of the tail, as well as a simple hemipenis completely covered in calyces with a largely non-bifurcated sulcus spermaticus.
• Although everted hemipenis could hardly be seen by the observers, the pair of everted hemipenis are protruding out of the male cloaca, and one of them is intromitted (inserted) into the female's cloaca, an act called hemipenis intromission.
• Convergences with Delma fraseri and Delma petersoni suggest that an approximately symmetrical, bi-lobed, and relatively unornamented hemipenis may be the ancestral condition of Delma.
