Strong agonistic behavior by a male L. plei showing the "lateral display" body pattern to another male whose head is visible at the right. The tail of the female squid who he is guarding can be seen to the left of his head. The primary components of this pattern are the vivid lateral flame markings on the side of the mantle and the dark crimson ventral ridge visible along the bottom edge of the mantle. This ventral ridge is actually a fold of skin that is muscularly protruded downward in this body pattern. The lateral flame markings are typically expressed only unilaterally on the side of the squid facing the opposing male.
