Two male Loligo plei in a dramatic agonistic bout for supremacy among the resident males in this laboratory tank. Note that the brilliant red flame markings are only displayed unilaterally on the side of the squid facing its opponent. These bouts often include violent body contact and fin beating. However they do not typically result in any physical injury.
