What is "pandaka"

Pandaka is a genus of fish in the goby family, Gobiidae, native to fresh, brackish and marine waters of Asia and the western Pacific Ocean. Some species in the genus are among the smallest fish in the world; the male P. pygmaea can be just 9 millimeters long at maturity.

The genus name is from the Sanskrit pandaka.

Not to be confused with Pandaka (fish), a kind of fish.

Pandaka is a Sanskrit and Pali sexuality term which does not have precise English translation, but incorporates (or perhaps confuses) multiple concepts associated with immaturity, voyeurism, impotence and infertility. It has been studied under the auspices of Theravada Buddhist thought.
