  • Subtitles section
  • Great white sharks are some of the most iconic and yet feared creatures on the planet.
  • In popular media, their dorsal fins are among the most represented symbols of danger in nature,
  • Their dorsal fin is as beautiful as it is iconic
  • but why do they display it?
  • And, does the dorsal fin function outside of its role in swimming?
  • To understand this, we have to first understand its primary role.
  • Because it is located on the shark's back
  • it plays a crucial role in maintaining stability and balance while swimming.
  • Simply put, sharks rely on their dorsal fins to keep them upright in the water
  • and to prevent rolling or tilting to the side,
  • This is especially important for a predator like the great white shark
  • which needs to maintain precise control and agility during hunting,
  • The simple fact that it's displayed so often may just have to do more with its body placement and the fact that sharks frequently swim near the surface for various reasons
  • other than for the purpose of simply displaying it.
  • One theory is that great white sharks display their dorsal fins as a warning to other animals,
  • This theory suggests, it can be a deterrent to the other predators as well as prey animals
  • but it's just a theory.
  • What is certain is that many sharks suffer from injuries to their fins
  • exactly because of their placement,
  • This shark, for example
  • appears to have a bent fin as a result of a gash caused by an unknown object,.
  • But sharks are resilient.
  • In the world they live in, it's a requirement.
  • I actually found the exact same shark seventy miles away
  • just six months later,
  • Notice the dorsal fin has healed in its bent position.
  • How this will affect the shark later in life
  • has yet to be seen,
  • But by all means, the shark seems to be moving fine.
  • A true measure of their resilience.
  • It's even displaying flaring gills
  • and movements I document with normal
  • healthy sharks,
  • Understanding the importance of the dorsal fin helps us appreciate the adaptions that enable these remarkable predators to thrive in their oceanic environments.
  • I've often recorded sharks moving towards objects
  • and bump them with their dorsal fin,
  • Sometimes it is absolutely beautiful.
  • Recently, I recorded something that begs more questions than answers,
  • Something I think is very telling.
  • Watch closely.
  • Did you see it?
  • Here it is again.
  • Did this shark just purposely move its dorsal fin to strike at an object,?
  • Maybe the dorsal fin serves more than just stability.
