The New zealand arrow squid, or Wellington flying squid, (Nototodarus Sloanii), is a species of squid a favoured prey species of a number of marine mammals and diving birds. For example, New zealand arrow squid is an important food source for the endangered yellow-eyed penguin, (Megadyptes antipodes). Furthermore, N. sloanii is sought by trawler fishermen for human consumption; in this trawling process, australian sea lions are frequently killed, since they prey upon N. sloanii.
