On January 29, 2025, the ICAR-Central Marine Fisheries Research Institute (CMFRI) announced a significant breakthrough in marine biology by successfully decoding the gene expression pattern of the Indian squid (Uroteuthis duvaucelii).

Led by Principal Scientist Sandhya Sukumaran, the study reveals surprising insights into the intelligence and brain development of squids.

The research suggests evolutionary connections between squids and higher vertebrates, positioning squids as potential model organisms for studying the evolution of intelligence and brain development.

Squids are known for their advanced nervous systems, problem-solving skills, and complex behaviors, including camouflage and jet propulsion.

Understanding the brain development of squids may yield groundbreaking insights into neurobiology, learning, memory, and neurological diseases.

These findings have significant implications for various fields, including neuroscience and environmental science, particularly highlighting genetic similarities between squids and humans.

Moreover, the findings may enhance studies on neural circuits and contribute to sustainable marine resource management.

Previously, the CMFRI demonstrated its commitment to marine biological research by decoding the whole genomes of the Indian oil sardine and Asian green mussel.
