Description

The priapiumfish is a remarkably small fish (Phallostethidae) from coastal and brackish water of Southeast Asia. The species grows to only about 3 cm and has a slender, translucent body. The male carries a complex copulatory organ, the priapium, beneath the head, with which internal fertilisation takes place, unique among small fishes. As a schooling fish it swims in estuaries and mangroves and eats minute zooplankton. The fish is harmless to humans.
