Campbell's keeled glass snails have reached a major conservation milestone on Norfolk Island. Over one thousand critically endangered snails have now been released onto the island. This marks a significant comeback after the species was presumed lost for decades. The successful recovery program involved extensive collaboration and captive breeding efforts. Researchers will continue monitoring the snails to ensure population growth and survival.

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.
