Patiriella regularis is a small five armed seastar, introduced to Australia from New Zealand. (1816). Human activities in the marine environment have led to the creation of extensive areas of artificial habitat (e.g. Patiriella regularis was found between 2–14 m and 4–14 m in Milford and Doubtful Sounds respectively.Patiriella mortenseni was found between 4 and 20 m in both sites.

Patiriella calcar and P. exigua inhabit intertidal rock platforms where they are found in close proximity, … The New Zealand sea star is biologically very similar to the Derwent River sea star, and consequently it is believed that the native species may have been genetically swamped by the invader. Oviposition is probably through the popular pores and newly hatched larvae may leave the host via the same route or through the stomach wall. 377314  Density estimates based on counts of seastars from the 0.25 m −2 photo-quadrants and total area for each species was based only on the depths where they were found.
