Two researchers diving off the coast of Turkey in 2011 captured what they claim is the first-known video of two cuttlefish engaged in a physical battle. The newly released footage, recorded by Justine J. Allen and Derya Akkaynak, features a perturbed and feisty cuttlefish defending its mate from an interloper.

Cuttlefish usually settle their differences by flashing intimidating patterns at their rivals, made possible by their amazing ability to manipulate millions of color cells found in their skin.

Physical melees are thought to be unusual because such violence could damage the cuttlefishes’ skin, hampering their ability to camouflage and protect themselves.
