'This can't be right': Big sharks found in waters far from the open ocean
The broadnose sevengill and the soupfin sharks are common along the Pacific coast. Now they're showing up in Washington’s Puget Sound.
Nature is fascinating!

They can…the book Peter Benchley wrote that ended up in the movie Jaws was based on a bull shark that swam into the Manasquan River in NJIt seems like I read somewhere that bull sharks can adapt to fresh water.
Some East coast river in the good ole USA and some river in Australia.
I could be wrong about that cause it was many years ago.
They could add orca to their culinary palatesIt doesn't seem that surprising that broadnose seven gill sharks might invade Puget Sound. According to WDFW, individuals of this species are found seasonally in both Willapa Bay and Grays Harbor for pupping and for mating. Bluntnose six gills sharks have been reported to use Puget Sound for pupping and as a nursery area (though their numbers may be declining - see here). So, I wouldn't be surprised to find that the broadnose seven gill sharks find the habitat of Puget Sound suitable for the same purpose. And if they get peckish, they are likely to find many menu choices; seven gills are very catholic in their potential diet, with a sweet-tooth for marine mammals (30% of their diet off Patagonia, but likely scavenged, not directly predated), including pinnipeds and cetaceans.

Actually, who is lunch and who is the eater is likely to be the other way around. Two killer whales (Port and Starboard) off South Africa have become specialists on the fat-rich livers of great white sharks and broadnose seven gill sharks (see some details here). Their predation has largely driven great white sharks out of the coastal waters of South Africa, where these sharks had been quite abundant (and well-studied). There are two "morphotypes" of killer whales off South Africa, type A and type B. Type A individuals tend to be marine mammal specialists (dolphins, small whales, seals) but have been observed to kill a great white shark. They have small pods of 6 or fewer individuals. The type B individuals have highly worn-down teeth, presumably for feeding on sharks with their highly abrasive skin. The two types are not easy to distinguish in the field and I don't know to which group Port and Starboard belong. [Edit: actually Port and Starboard are type B individuals, both older adult males (see here).]They could add orca to their culinary palates

Now to find out if they’ll eat a fly.
Males only get to about 5’ and females to about 7’. Randy’s flies are too big.Nobody tell Clarkman.
