Zookeepers in the Czech Republic are struggling to get
two frightened female frogs to come out of their cages after
bringing in a giant three-pound bullfrog to mate with them.
The rare burrowing bullfrog, found in southern Africa,
was introduced to two females of the same species at Plzen
zoo last week.
But the two females immediately ran for cover and buried
themselves in the ground at the bottom of their cages when
they saw the size of the bullfrog, Czech agency CTK reported.
Zoo spokesman Martin Vobruba said: "We placed the
male and his two wives in a section of the zoo called The
Mysterious World of the African Night. The females, however,
have shown no enthusiasm so far."
Chief zoologist Vitezslav Honsa added: "We even went
as far as getting a tape for them with frog sounds on it
so they could make love."
