The northern Pacific sea star is one of the largest sea stars in the ocean but can spell disaster for local wildlife.
These sea stars have a nearly insatiable diet and will happily eat all the shellfish New Zealand has to offer. These creatures can also disrupt the aquaculture business in the area because they will stick to fishing nets, crates, and other tools.
The northern Pacific sea star typically has only five arms that point upward at the ends. These marine creatures are usually yellow or orange with some purple lines and markings to set them apart.
