Common thresher shark [Walter Heim/NOAA] |
Common thresher shark Alopias vulpinus
Common thresher sharks are found along the continental shelves of North America and Asia of the North Pacific, but are rare in the Central and Western Pacific. This species tends to be more common in coastal waters over the continental shelves. Caught incidentally in the commercial fishery off the outer Washington coast with longline, troll, and jig handline gear. This species of shark is a very fast, strong swimmer and has been known to leap entirely out of the water! This shark can also maintain a body temperature warmer than the water surrounding it, a trait it shares with its relatives: makos and great whites.

Decision 50 years on — much done, much to do
More shark talk
Our man on Lopez shares: "The Greenland shark, a close relative
of the Pacific species, has the longest known lifespan of all
vertebrate species, estimated to be between 250 and 500 years! This
suggests that there are sharks alive today that were youngsters before
the U.S. became a country. It reaches sexual maturity at about 150 years
of age and pups are born alive after an estimated gestation period of
8–18 years (also the longest of any known vertebrate). The flesh
contains a high concentration of a nitrogen compound that causes the
meat to be toxic to mammals. Greenland shark flesh, treated to reduce
toxin levels, is eaten in Iceland as a delicacy known as hakarl. From
personal experience, my wife and I concur that the so-called “delicacy”
tastes like a sponge soaked in household ammonia."

Reduce, reuse, redirect outrage: How plastic makers used recycling as a fig leaf
The plastics industry has worked for decades to convince people and
policymakers that recycling would keep waste out of landfills and the
environment. Consumers sort their trash so plastic packaging can be
repurposed, and local governments use taxpayer money to gather and
process the material. Yet from the early days of recycling, plastic
makers, including oil and gas companies, knew that it wasn't a viable
solution to deal with increasing amounts of waste, according to
documents uncovered by the Center for Climate Integrity. Michael Copley
reports. (NPR)
Bill seeks to improve ferry reliability with a work group
House Bill 2497 would create the Washington State Ferries 75 Work Group,
a reference to Washington State Ferries’ 75th anniversary in 2026.
While the state Department of Transportation isn’t completely on board,
Rep. Greg Nance thinks his bill will help ferries long-term. Jenelle

Where could the United States mine in its own seabed?
No longer the stuff of science fiction, the deep-sea mining industry is
speeding up efforts to mine precious minerals in international waters.
But some countries are looking to do so within their national
boundaries. Norway, for example, became the first country to allow
mining exploration in its own waters, and the United States may not be
far behind. Elham Shabahat reports. (Hakai Magazine)
Whidbey diver-turned-citizen scientist provides ongoing data
Longtime Whidbey diver Jan Kocian has circled the island exploring the
marine environment. It looks a lot different than it used to, he said.
“That diversity is gone,” he said. “It’s unfortunately in every location
on the island. The diving is not even close to what it used to be. I
know I sound like an old guy.” According to the Pacific Biodiversity
Institute, the Salish Sea was one of the most productive and diverse
marine ecosystems in the world and has seen a 300-year decline caused by
overfishing, by-catch, pollution, dredging and coastal development. Sam
Fletcher reports. (South Whidbey Record)
