They were introduced into waters in south east Tasmania, where they have become well established.[1] Concern exists that they may be an invasive species. They breed in January to March. Once fertilised, 9–10 weeks are needed for them to grow from larvae.
Research
A genetic variance is found in P. regularis from the North and South of New Zealand.Geographic barriers, and coastal upwellings might keep various types of P. regularis from being able to spread or comingle.[2]

gollark: You'll see. You'll all see.
gollark: I think I cause a substantial fraction of reminders.
