Photographers and filmmakers from National Geographic are known for capturing nature in its most candid moments.
In a National Geographic video posted Tuesday, snorkelers swimming in Oahu, Hawaii, stumble upon an underwater battle between a moray eel and an octopus.
The eel manages to bite off one of the octopus' tentacles, which isn't too big of a deal since an octopus can easily regrow another without any permanent damage. Despite such tense moments, the lucky octopus swims away after spraying the eel with ink.
But the excitement doesn't end with the sea creatures. The human witness becomes part of the action when the eel notices the camera and doesn't appreciate his defeat being caught on film. Thankfully, the snorkeler is a fast swimmer.
