Did you know Porbeagle Sharks (Lamna nasus) can live in almost freezing waters?!

It's so cold humans would lose consciousness in <15 mins! These sharks survive by warming important parts of their body up, called regional endothermy!

It's Today is the Salmon Shark (Lamna ditropis)!

lamna= shark (greek)
di = two (greek)
tropis = keel (greek)

All together-> TWO KEEL SHARK!

Spot on!
(The two keels/ridges at the base of the tail help to identify it as a salmon shark instead of a great white)
