Common characteristics include the positioning of the pelvic fins (if present), below or in front of the pectoral fins.

The larvae typically have protective spines on the head, over the gills, and in the pelvic and pectoral fins.

Now, finning is the act of taking a shark, cutting the valuable fins off and throwing the live animal back in the water.

So we can save the bluefin tuna.

We've actually taken a sliver of the ocean, put it behind glass, and we together have put bluefin tuna and yellowfin tuna on display.

Here, for over 14 or 15 years, we've actually brought in both bluefin and yellowfin in captivity.

Bluefin are in cave paintings in France.

I put my flippers on. I could barely part my lips.

Bluefin are pursued wherever they go there is a gold rush on Earth, and this is a gold rush for bluefin.

Bluefin are warmblooded like us.

Bluefin have two populations one large, one small.

But the radical sign implies the principal root.

We're taking the principal root, the positive square root.

The square root of 16 times 2 is the square root of 16 times the square root of 2.

So the square root of 12 is equal to square root of 3 times square root of 4.

The square root of 2 times the square root of x.

Square root of 4 over square root of 9, times x.

Times the square root of 5 times the square root of s.

Now bluefin, in general, goes to one place Japan.

The anal opening is under the head or the pectoral fins.

Now bluefin, in general, goes to one place

Meanwhile, Ernest finds his fins on the internet.

So square root of 2 times 2 times the square root of 5 times the square root of 9.

So we take the square root of both sides, you get I is equal to the square root of 3 over the square root of 4.

AND BE CAREFUL HERE, IF WE JUST TAKE THE PRlNClPLE ROOT, THE PRlNClPLE ROOT HERE IS THE POSlTIVE SQUARE ROOT

Times the square root of three, times the square root of three

Square root of three times square root of three

So b is equal to 36 minus 20 is 16. So square root of 16 over square root of 5.

It's going to be the square root of this times square root of that.

Square root of 12 is the same thing as the square root of 3 times the square root of 4.

The principal square root of 4 is 2, so this all simplifies and we can switch the order over here this is equal to 2 times the square root of 13 2 times the principal square root of 13, I should say, times i.

And this is just going to be equal to the principal root of 5x.

We are looking for the principle root of this is the same thing, this is the same thing as d times the principle root of 4 times the principle root of d to the fourth, times the principle root of d to the fourth

The name Dicentrarchus derives from the presence of two dorsal fins.

That's one of our bluefin at the Monterey Bay Aquarium.

Some of you may be guilty of having contributed to the demise of bluefin.

And voila, next day air, they show up, and they surgically reattach them.

There are actually three species of sharks here.

Then the artist spreads the fins out and pins them down on the board to dry.

Now this guy, this bigfin squid, is seven meters in length.
