Recent studies reveal that Greenland sharks possess well-preserved visual systems that can last for centuries, challenging the previous notion that they were nearly blind. Research shows that their eyes are uniquely suited for low-light environments, demonstrating impressive adaptability. Scientists found healthy rod cells and active genes responsible for light detection, indicating these sharks have a remarkable ability to maintain their eyesight throughout their extended lifespans.

For the first time, Brazil faces a significant challenge as bacteria previously exclusive to Asia and the USA have been identified within its borders. These bacteria, known to cause columnaris disease, pose an acute risk to the thriving aquaculture sector.
