Pseudobiceros bedfordi
''Pseudobiceros bedfordi'', (common names Persian carpet flatworm〔(Persian carpet flatworms (Pseudobiceros bedfordi) on the Shores of Singapore )〕 and Bedford's flatworm) is a species of flatworm in the family Pseudocerotidae.〔(WoRMS - World Register of Marine Species - Pseudobiceros bedfordi (Laidlaw, 1903) )〕
This species has two penises, which it uses to ''fence'', in an attempt to inject sperm into its opponent in order to fertilize it, while avoiding being fertilized itself.〔Arnqvist, Göran; Rowe, Locke (2005), ''Sexual conflict'', Princeton University Press, ISBN 978-0-691-12218-2, p. 185〕
