Penion mandarinus explained

Penion mandarinus, common name the mandarin penion, southern siphon whelk or Waite's buccinum whelk, is a species of medium-to-large predatory sea snail or whelk, a marine gastropod mollusc in the family Austrosiphonidae.^{[1] [2]}

Description

Penion mandarinus is a medium-to-large sized species of siphon whelk.^{[3] [4]} The species could be confused with the sympatric species P. maximus, however P. mandarinus is typically smaller and has a smoother shell with a shorter siphonal canal.^[3]

Distribution

This marine species is endemic to Australia (New South Wales, South Australia, Tasmania, Victoria).^{[3] [5]}

Evolution

Penion mandarinus is closely related to another Australian species P. maximus.^[6] The species have overlapping geographic ranges (sympatry) and may have evolved from a common ancestor via niche differentiation based on prey size and water depth.^[6]

Subspecies

These subspecies have been previously recognised:

• Penion mandarinus mandarinus (Duclos, P.L., 1831)^[3]
• Penion mandarinus waitei (Hedley, 1903)
