A shark’s perspective

Dr. Carl Meyer (University of Hawaii) and Dr. Katsufumi Sato (University of Tokyo) have teamed up to gather data about shark behavior in a rather interesting way. They flipped the animals upside down, which makes them relax, and strapped on cameras and instruments that will facilitate the creation of 3D models of shark movements. Using…

Great White Shark Longevity

Scientists have discovered that great white sharks (Carcharodon carcharias) actually live longer than previously thought (up to 23 years or so). Using radiocarbon age estimates, Dr. Hamady and colleagues at Woods Hole Oceanographic Institution determined the animals can live to the ripe-old-age of 70+ years. These findings mean that great white sharks, like humans, may…

Dr. Michael Stanhope from Cornell University has discovered that great white sharks actually share more proteins involved in metabolism and biochemistry in common with humans than zebrafish, a common fish model used in biomedical research. They made this discovery by sequencing the transcriptome of a heart isolated from a great white shark. I find it…
