Boy or girl? Japan zoo tries to mate two male hyenas, determines sex by tests
Following years of fruitless attempts, the Maruyama Zoo
discovered this week that they were not going to get baby spotted
hyenas from the “couple” they received in October 2010, AFP
It is only after conducting several tests that the zoo realized its mistake.
“We have determined that the two animals are both male after conducting ultrasound imaging and hormone tests on them under anesthesia,” the agency quoted the zoo’s statement as saying.
The Japanese zoo, located in the northern city of Sapporo, said
the two animals were given to them as a gift by South Korea and
were labeled as a “male and female couple.”
“We have attempted to house them together for breeding many times but they often fought against each other and never engaged themselves in breeding behavior,” the statement added.
The zoo did say that determining the sex of a hyena can be “extremely difficult.”
However, attempts at mating are not over just yet; one of the two male hyenas – Kami or Kamutori – will now be chosen for a female partner.
“We still plan to obtain a female spotted hyena for breeding with either Kami or Kamutori,” the zoo said.
