An intimidating ornament in a female pipefish Sex chats real people
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.
Due to pipefish's narrow distribution they are unable to adapt to new habitats.
In this virtual issue we revisit this debate and highlight some of the articles that have examined reproductive competition among females and its evolutionary consequences for female sexual signalling.
Intrasexual competition in females: evidence for sexual selection?
Aquarium trade of pipefish has also increased in recent years.
Local and national fishing restrictions have been put into effect to help protect this vulnerable order of fish.
Most pipefishes are marine dwellers; only a few are freshwater species.The dance involves very conspicuous wriggling and shaking motions, especially in comparison to the species' otherwise extremely secretive lifestyle.
