Male shark - claspers borne on pelvic fins

Vedclass · Answer

(D) is the correct answer.In $Ascaris$,the female has a straight tail end,while the male has a ventrally curved tail end.Anal cerci are present in both male and female cockroaches,whereas anal styles are present only in males.In frogs,the nuptial or copulatory pad is found on the first digit of the $forelimb$ (not hind limb) in males,which helps in gripping the female during mating.In male sharks,the pelvic fins are modified into structures called claspers,which are used for copulation. Thus,the presence of claspers is a reliable feature to identify a male shark.
