Boat Followers!


This is crazy cool video!

"Story" here.
Apparently filmed in the Gulf of Carpentaria - and if so, would those be limbatus or tilstoni?
JSD?

Enjoy!

The method for answering this is very simple.

1) Measure the horizontal diameter of the eye (in mm).

2) Measure the distance from the center of the eye to the top of the first gill slit.

3) Subtract 1) from 2) to get A.

4) Measure the distance from the tip of the first dorsal to the tip of the upper lobe of the caudal fin.

5) Measure the distance from the tip of anal fin to the tip of the lower lobe of the caudal fin.

6) Subtract 5) from 4) to get B.

7) Multiply A and B to get C.

8) Measure the distance from the tip of the first dorsal to the tip of the snout.

9) Measure the distance from the pelvic fin to the 5th dorsal fin.

10) Subtract 8) from 9) to get D.

11) Divide C by D to get E.

12) Whatever answer you get proves it's either limbatus or tilstoni.
