Kinds of Hermaphroditism
Depending upon the timing of maturity of the gonads, hermaphroditism can be of two types
1. Simultaneous hermaphroditism. Both male and female gonads mature at similar time. Some common instances are liver flukes (Trematoda), tapeworms (Cestoda) earthworms, leeches, pulmonate gastropods etc.
2. Protandrous hermaphroditism. (gk protos: first, andr: man/male). Male gonads mature first. This condition is common in some molluscs such as limpets and slipper shells (Crepidula).
