Pursuit predation with intermittent locomotion in zebrafish

AP Soto, MJ McHenry - Journal of Experimental Biology, 2020 - journals.biologists.com
The control of a predator's locomotion is critical to its ability to capture prey. Flying animals
adjust their heading continuously with control similar to guided missiles. However, many …
