Innovative Problem-Solving in Atlantic Cod
Atlantic cod have demonstrated remarkable problem-solving abilities through a study involving self-feeding devices. Researchers utilized colored beads attached to the fish to track their actions, revealing that one fish became adept at getting trapped in the device only to intentionally escape, showcasing an understanding of its own limitations. This fish learned to utilize its hindrance to gain advantages, orchestrating its movements to successfully retrieve food while managing the constraints of the device. Ultimately, this behavior reflected a higher level of cognitive function, indicating the potential for tool use and planning in fish beyond initial expectations.
