The Great White, Remoras and Orcas

In this post we will be talking about the famous great white shark and the great white's little helper, remora. Now, remoras look like parasites to us humans. But really, remoras are the opposites of pests, they actually eat the pests. From millions of years from evolution, the remora kind of looks upside down when they are right side up. It might be because of its suction head. Remoras latch on to sharks while they have suction cups on their head. The great whites and other sharks don't usually eat remoras. There's also this other kind of fish that cleans the shark's teeth.

Now we will talk about the shark or rather the great white shark. The great white shark is a living torpedo. No really, its like a cruise missile (the cruise missile is a very powerful weapon). Now you may think those ol' great white sharks are super bulky to catch up to a seal lion, but actually the great white shark has amazing agility. In fact they sometime leap out of the water with the prey still in its mouth.

Now you may think that no one would mess with a great white shark, but really there are two predators that will mess with the great white. The creature is called the orca, also known as killer whale, but really its a dolphin. Most people call it a whale. And people call it a killer whale. Instead they should call it a killer dolphin. Now orca whales pretty much hunt in packs, but the great white shark can dive deeper. And here's the other predator of the great white... US HUMANS! Some people like to make shark fin soup out of them. And the worst thing us humans do: we hunt them for sport. Sport! That means really getting nothing out of it. Its just killing. And there may be less sharks than they think, because no one great white shark looks the same. On the plus side we have been putting tags on them.
