**Kochi, India –** Scientists at the ICAR-Central Marine Fisheries Research Institute (CMFRI) have made a significant breakthrough in understanding the Indian squid (Uroteuthis duvaucelii), decoding its gene expression pattern and revealing surprising similarities to humans. The study, led by Principal Scientist Sandhya Sukumaran, has uncovered insights into the squid’s advanced nervous system and its implications for neuroscience, intelligence research, and even the study of neurological diseases.
The research highlights the squid’s exceptional problem-solving skills and complex behaviors, including camouflage and jet propulsion, all stemming from a sophisticated brain. The decoded gene expression profiles reveal genetic similarities with higher vertebrates like fish and humans, suggesting significant evolutionary connections. Understanding the squid’s brain development, according to Sukumaran, could offer groundbreaking insights into neurobiology and the evolution of complex nervous systems.
The study’s findings are expected to have wide-ranging applications. The CMFRI suggests the research will be crucial for sustainable marine resource management and in understanding how marine life adapts to environmental change. The abundance of Indian squid in the ocean, combined with its intelligence and complex behaviors, makes it a valuable model organism for this kind of research. This research follows previous work by Sukumaran’s team, which decoded the genomes of the Indian oil sardine and Asian green mussel. The study opens exciting new avenues for neuroscience, evolutionary biology, and marine conservation efforts.
