Saturnyn

The Saturnynians were an exo-skeletal, insectoidal species of fish from the planet Saturnyne. They were notable for their many limbs and their two curved canines. They constantly needed to either consume or come in contact with water and this included moisture in blood. If ever they used perception filters, their teeth would remain and they would smell vaguely of fish. (DW: The Vampires of Venice)
