Not Your Average Fish: Tuna Shares ‘Super Predator’ Genes With Great White Sharks

pacific bluefin tunaDespite independent evolution for 400 million years, sharks and tunas still share common genetic traits. They include higher metabolism, body temperature and fast swimming skills. In the lamnid group of sharks, great white sharks are a major presence. Some common genetics make them super predators with brisk swimming power and the ability to stay warm. This was revealed in a new research by Imperial College London which asserted the commonality of genes in the two groups as key to their predatory edge. Regarding the identical genes in both the groups, the team said they are mainly linked with metabolism and the ability to produce energy. The study, published in Genome Biology and Evolution Journal, had Professor Vincent Savolainen from the Department of Life Sciences at Imperial as the Co-author. “Lamnid sharks and tuna both have stiff bodies and tails that allow them to swim in bursts. They can also keep their temperature up in colder waters. Both of these things make them more effective predators, allowing them to snatch prey in usually inhospitable waters,” Savolainen said.
