Kaikoura is an area of high
biological productivity that sustains large, diverse populations of
marine mammals, fishes and invertebrates. Sperm whales,
particularly young males, occur throughout the year in
inshore waters, although separate seasonal populations may be
represented. This year-round availability of whales supports a
rapidly growing whale watch industry with a world wide clientele.
Sperm whales prey predominantly on cephalopods, particularly on squids, at depths of 400-600 meters and deeper. The dominant, large squids habitually captured by sperm whales generally are not captured in trawl nets, and rarely are they seen from submersibles.
The geographic, near-shore, confined features of the Canyon, the year-round presence of sperm whales, high productivity and biodiversity, abundance of squid as whale prey, all signal the area as an excellent study site to document and define a deep sea community through the prey/predator relationships of its top level predators.
