flag Hector’s dolphins use unique feeding tactics at different depths, aiding conservation efforts in New Zealand.

flag Scientists using DTAGs on Hector's dolphins, the world’s smallest marine dolphins, observed deep dives up to 120 meters, barrel rolls, and upside-down feeding near the seafloor. flag The dolphins adjusted their feeding strategies based on location—cruising slowly near the bottom for flatfish and cod, and rolling in midwater to catch schooling fish. flag The data helps assess risks from fishing gear and vessels, supporting better management of Marine Mammal Sanctuaries and conservation efforts under New Zealand’s Threat Management Plan.
