The evolution of male brooding in pipefish is thought to be a result of the reproductive advantage granted to pipefish ancestors that learned to deposit their eggs onto the males, who could escape predation and protect them.

Furthermore, the ability to transfer immune information from both the mother (in the egg) and the father (in the pouch), unlike other chordates in which only the mother can transfer immune information, is believed to have an additive beneficial effect on offspring immunity.

These disturbances cause a decrease in seagrasses and eelgrasses that are vital in pipefish habitats.
