Future research might investigate whether comparable human semen proteins have similar effects, investigators added.

Scientists investigated the longfin squid (Loligo pealeii), which live for nine to 12 months, usually mating and laying eggs in the spring, when the animals migrate from deep offshore waters to shallower waters along the Eastern Seaboard from North Carolina to Maine. Females mate several times with multiple males, who compete fiercely over females.

While in the field, scientists noticed that male squid were visually attracted to the tens of thousands of eggs laid on the seafloor. After just one touch of the eggs with their arms or heads, the researchers found that males immediately and dramatically went from swimming calmly to extreme aggression, including grappling, fin beating and forward lunging.
