Hector’s dolphins are near the top of the food chain and likely play an important role in regulating local fish populations. During the spring and summer, white-fronted terns (Sterna striata) feed with Hector’s dolphins, likely as facultative commensalists, by capturing small fish being chased by dolphins.
