Yes, sharks likely feel pain and distress when hooked, possessing pain receptors (nociceptors) and showing responses to harmful stimuli, though their nervous system differs from mammals, leading to different expressions of suffering, such as struggling to escape rather than vocalizing or showing human-like fear, suggesting they experience a version of pain, not just reflex. While some older theories claimed they couldn't feel pain due to lacking a neocortex, newer research confirms they have the neurological equipment to perceive harm, even if their reaction is to keep moving to survive.Will a Shark Really Die if it Stops Swimming?
