Such attacks are connected by a couple crepuscular levels (beginning and you may dusk) in which an increase regarding direct affairs ranging from predators and you will sufferer exist. It overall trend was well documented in diverse ecosystems and you can seafood communities that have multiple studies highlighting the importance of crepuscular episodes as the a behavioral, ecological and you may ecological change [twenty-five,forty-eight,forty-two,50].
