Spinner dolphins take advantage of the nightly migration that brings their prey species to shallower depths and closer to shore by feeding throughout the night. Herding exploited the prey's own avoidance behavior to achieve food densities not observed otherwise.

They will corral fish into tight packs and then send a few dolphins at a time flying through the pack to catch a meal. Unlike us, they need to keep part of their brain active and actually think about breathing in order to take a breath. Bowriding. While we are not positive why spinners perform these acrobatics, marine biologists think it may be a form of communication. Blackwell, Oxford,Boyd II (1996) Temporal scales of foraging in a marine predator. 1 2 3. The overlap of Hawaiian spinner dolphins and their prey at many temporal and spatial scales, ranging from several minutes to an entire night and 20 m to several kilometers, indicates that the availability of truly synoptic data may fundamentally alter our conclusions about pelagic predator-prey interactions.This is a preview of subscription content.Immediate online access to all issues from 2019.
