Bidder's canal is present inside kidney of frog. It receives sperms from testes via a number of vasa efferentia.
Explanation:
Testes lies very close to kidney in frog. From each testes 10 to 12 vasa efferentia arise to enter kidney of same side. These will open in Bidder's canal: a duct carrying sperms and running longitudinally through kidney.
In frogs, urine produced by nephrons will flow into the ureter from longitudinal collecting duct. Bidder's canal remains connected to this by several transverse collecting tubules.
Ureter of frog is an urinogenital duct as it is the outlet for both urine and sperms from kidney.
