CLASPERS IN SHARKS:
In male shark claspers are present. The claspers are rod like copulatory organs present on the inner borders of the pelvic fins. They are supported by carfilages. Each clasper has a groove on its dorsal side. The groove is opened at both the ends. Its anterior opening is called the apopyle and the posterior opening the hypopyle communicates with the cloaca. It receives the sperms from the cloaca. The hypopyle is as an exit for the sperms into the cloaca of the female.
