Cognitive studies on fish often overlook the vast majority of the 30,000 species, predominantly focusing on a few well-studied ones. Laboratory settings may induce stress and limit complex behaviors, failing to capture true cognitive capabilities. A new low-cost cognitive testing apparatus has been developed for use with various fish species in their natural habitats. This advancement may shed light on the real cognitive abilities of fish, showcasing their potential beyond traditional lab-based assessments.
Researchers created a cognitive testing apparatus applicable across diverse fish species, allowing examination of cognition in their natural habitats, revealing more about their cognitive abilities.
Goldfish do not possess a mere three-second memory. Fish can distinguish individuals, navigate using mental maps, cooperate, communicate, build structures, use tools, and track quantities.
