Generally, the false killer whale targets a wide array of squid and fish of various sizes during daylight hours.[1][22] They typically target large species of fish, such as mahi-mahi and tuna.[23] In captivity, it eats 3.4 to 4.3% of its body weight per day.[4] A video taken in 2016 near Sydney shows a group hunting a juvenile shark.[24] It sometimes discards the tail, gills, and stomach of captured fish, and pod members have been known to share food.
