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. [10] [11]
Penion mandarinus is a medium-to-large sized species of siphon whelk. [12] [13] 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. [12]
This marine species is endemic to Australia (New South Wales, South Australia, Tasmania, Victoria). [12] [13] [14]
Penion mandarinus is closely related to another Australian species P. maximus . [13] [15] 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. [15]
