Greenland shark is longest living vertebtrate

A recent study showed that the greenland shark, an animal that scientists had previously suspected was long-lived, can reach ages of nearly 400 years.  Previous research in the 1930s had shown that these fish, which can grow up to 5 meters in length, only grow about 1 centimeter per year.  This is a surprisingly slow growth rate, even for the extreme cold in which the shark lives that slows down metabolism and in turn reduces growth rates.  The new study places greenland sharks as the oldest known vertebrate.

About the Author:

Jacob Allgeier
I am an ecologist with broad interests in how human-induced changes alter how ecosystems function and the services that they provide. A central focus of my research is understanding how changes in biodiversity affect the flow of nutrients and energy in ecosystems. Most of this research takes place in tropical coastal ecosystems such as mangroves, seagrass beds, and coral reefs. I am an assistant professor at the University of Michigan, Ecology and Evolutionary Biology.
