Nototodarus sloanii is a species of squid commonly known as the New Zealand arrow squid or Wellington flying squid. It is also known by its Māori name of Wheketere. It is a favoured prey species of a number of marine mammals and diving birds. It is an important food source for the New Zealand fur seal and the endangered species: New Zealand sea lion and yellow-eyed penguin (Megadyptes antipodes). 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.
