The salmon shark is generally viewed as potentially dangerous to man.

Several species of sharks have been taking advantage of magnificent yellowfin tuna action off the coast of North Carolina. When anglers have a tuna on the line, the big-toothed predators move in for the kill, leaving just the head or mangled body to reel in.
Shark is not a word most people associate with Alaska . There are three shark species commonly found in Alaskan waters: Pacific sleeper shark (Somniosus pacificus), spiny dogfish (Squalus suckleyi), and salmon shark (Lamna ditropis). Three of the four most vulnerable species were sharks .
Salmon sharks are closely related to great white sharks . Salmon sharks have the ability to regulate their body temperature 14 to 20 degrees Fahrenheit above the ambient water temperature. Maximum age for salmon shark males is 25 years and for females 17 years.
Predators. When in the water, penguins may be eaten by leopard seals, fur seals, sea lions, sharks , or killer whales.
These species, which are frequently found in shallow water, would struggle crossing the deep ocean surrounding the southernmost continent. Thus, no sharks in Antarctica … Closer to home, the Atlantic White Shark Conservancy has been witnessing what happens when sharks get too cold.
