Monoplex parthenopeus

This species have been recorded as fossils from the Miocene to the Quaternary (from 15.97 to 0.0 million years ago).[5]

This species occurs worldwide including:

• The Western Atlantic Ocean[4]
• New Zealand[6]

The maximum recorded shell length is 180 mm.[7]

Minimum recorded depth is 0 m.[7] Maximum recorded depth is 75 m.[7]

Hairy tritons are notable for having particularly long planktonic periods. The veliger larvae remain in the plankton for nearly 300 days, dispersing as far as 4000 km.[8] This is the longest known larval duration and dispersal distance of any marine invertebrate which occurs along the west coast of North America.[9]
