Scientists saw orcas hit large fish very hard. They do not know why the animals did this.
Scientists saw orcas hit heavy fish called sunfish on two different occasions. The orcas hit the fish very hard. The fish broke apart from the force.
Scientists do not know why the orcas did this. Perhaps the animals wanted to break the fish into smaller pieces for their group to eat. Or perhaps they were just bored.
Scientists plan to watch more events like these. They want to learn more about what the orcas do and why they do it.
