Warm-blooded Fish?

Posted by Hemos on from the sounds-mighty-fishy-fishy-har-de-har dept.

DIY News writes "Scientists now have direct evidence that the north Pacific salmon shark maintains its red muscle at 68-86 degrees Fahrenheit, much warmer than the 47 F water in which it lives. The elevated muscle temperature presumably helps the salmon shark survive the cold waters of the north Pacific and take advantage of the abundant food supply there. The heat also appears to factor into the fish's impressive swimming ability."

    Damn reptiles... always trying to copy us!

    The next round of global warming is going to see warm blooded land-dinosaurs roaming the tropical forests of the North American continent. We'll all be sorry then!

      Along the discovery that salmon shark thermoregulate (duh), a more interesting discovery is the that of the fundamental division of Slashdot posters. No, not liberals and conservatives, not pro-Firefly and anti-Firefly, not religious and non-religious... no, the fundamental division are those with senses of humor and the psychological capability for detecting the same, and those without.

      ...that was until the commercial fishing and technology came along to start wiping them out

      The sharks evolved heaters to move into colder waters for more prey. The humans evolved fishing boats and nets to move into damned near any water for more prey. What the sharks need to do is evolve torpedoes as a defensive mechanism ...

      I was wondering why that boat was growing on my left foot. I guess random genetic mutation caused it to be there.
