TED-Ed: Can animals be deceptive? - Eldridge Adams

The video explores animal deception, highlighting how non-human animals use deceptive tactics to mislead others for their benefit. It covers examples like fireflies, geckos, and octopuses using mimicry and camouflage. Adaptive deception is seen in drongos, which use false alarms to steal food. Intraspecies deception is exemplified by mantis shrimp bluffing to protect their homes. The video questions whether animals deceive with intent, noting the complexity of their behaviors.
