They placed the male rhino in an enclosure with both female northern white rhinos in hopes to cross-breed the subspecies. Having the male rhino with two female rhinos was expected to increase competition for the female rhinos and, in theory, should result in more mating experiences. Ol Pejeta Conservancy did not announce any news of rhino mating.
The Indian rhinoceros (Rhinoceros unicornis) is also known as the greater one-horned rhinoceros, great Indian rhinoceros and Indian rhino.It is the second largest living rhinoceros species, with adult males weighing 2.07–2.2 t (2.04–2.17 long tons; 2.28–2.43 short tons) and adult females 1.6 t (1.6 long tons; 1.8 short tons).
Pregnancy of the female rhinos was monitored weekly. [22] Rhinoceros gestation takes 16 to 18 months, [23] so in January 2014 the Conservancy considered Najin not pregnant, and a male southern white rhino from Lewa Wildlife Conservancy was put to Najin and Fatu enclosure in Ol Pejeta to at least intercross the subspecies. To achieve this, both ...

Male Japanese rhinoceros beetles will use this horn to fight other males for territory and access to female mating partners. Upon contact, males will attempt to flip each other onto their backs or off of their feeding tree. [3] In response to selective pressures, smaller male A. dichotoma have adapted a "sneak-like behavior". These smaller ...
Male Japanese rhinoceros beetles (Allomyrina dichotoma) fight to dominate sap sites. Males use their horns to pry rival males off the area, which also may give them the chance to mate with a female. In this and other species that defend mating sites, larger males with larger horns mate more frequently, as they win more contests.
Xylotrupes gideon, male and females. Museum specimen. Xylotrupes gideon can reach a length of 3.5–7 centimetres (1.4–2.8 in). [7] As usual with rhinoceros beetles there is a great difference between the genders. Males are larger than females.
