Mr Wade has previously speculated that Nessie is a Greenland shark
that got trapped in Loch Ness.
This SI5N value is also higher than that reported for marine fish from the Arctic, including top predators such as the Greenland shark
(Somniosus microcephalus) (McMeans et al., 2013).
By measuring the size of the recent Greenland shark
found, researchers suggest the animal could have been born as early as 1505, making it even older than Shakespeare.
Author Morten Stroksnes (writer of several other praised reportage books) describes his efforts, alongside his old friend Hugo Aasjord, to catch a Greenland Shark
, from a R.I.B.
(The "drunkenness" referred to in the title comes from eating the flesh of the Greenland shark
, which contains compounds used in the nerve gas trimethylamine oxide.) Ranging over a full year, the quest for more than a nibble yields satisfying insights into friendship, aspirations and the thrill of the chase.
Tests have revealed the Greenland shark
(Somn/osus microcephalus) can live for at least 272 years, which so far is considerably longer than any other vertebrate we know of.
The scientists used radiocarbon dating to determine the approximate age of a female Greenland shark
(Somniosus microcephalics), who may well have been born before the Industrial Revolution.
Tagging experiments with the Greenland shark
(Somniosus microcephalus (Bloch and Schneider)) in Subarea 1.
The latest in birthday science proposes that the vertebrate with the longest life span yet measured is the mysterious Greenland shark
"By the thousands, they accidentally end up as by-catch across the North Atlantic, and I hope that our studies can help to bring a greater focus on the Greenland shark
in the future."
The fierce but seldom seen Greenland shark
, which has been found in Scottish waters, has a greater survival expectancy than even famously long-lived species such as whales, tortoises and turtles.
He added: "Nevertheless, a decomposing whale may prove impossible to ignore for a number of other magnificent oceanic sharks that are found in British waters, including the blue shark, porbeagle, shortfin mako, thresher - possibly even a Greenland shark
