My success is not that of my own, but the success of many” Firstly, I would like to acknowledge my supervisors Dianne Brunton and David Aguirre. Thank you for all of your guidance, for taking an idea that I had and helping make a project out of it. Thank you for giving up your time to read and analyse my work and for always keeping me on point. For helping me to define what I really wanted to study and trekking all over Auckland to find these little blobs of jelly stuck to the rocks. David, your brilliant mathematical and analytical mind has enhanced my writing, so thank you, without you I would have been lost. This would never have been finished without both of your input! Secondly, I would like to acknowledge my parents, Georgina Tehei Pourau and Iain Balfour. Your endless support, strength and enormous belief in what I do and who I am has guided me to this point. Thank you for scouting prospective sites and getting up early to collect anemones with me.

Cypris settled predominantly on the carapace (67%), mostly on the gastric area (40%), on the left or right orbital areas (35%), on the head appendages, and on the pereiopods 1–3. Encrusting individuals were mostly small (84%); medium-sized specimens accounted for 11% and large for 5%. On the cephalothorax, most were observed in branchial (661) and orbital areas (240). Only 40–41 individuals were found on gastric and cardiac areas. Some individuals (246), mostly small (95%), were observed on the dorsal portion of somites.
