Hello all! I have a HUGE bucket of Aurora Micro that I am slowly going through and I am hoping I am getting my ID's accurate, so I am posting what I think are each kind. Please confirm or address any wrong IDs. Thanks!! 

These are all micros, so around 1/8 inch - 1/4 inch or aprox 3-9mm

#1 is probably Sphyrna.

#10 looks like Carcharhinus isodon 

#15 is a lateral Carcharhinus 

#18 looks like a Carcharhinus symphyseal 

#20 has some serrations so it is probably a lateral Carcharhinus

#22 looks like Hemipristis 

The leaf shaped teeth are fish teeth, probably mackerel or small tuna.

#24 &#25 could they be barracuda teeth?

It’s possible but #24 looks like it has a bulge near the base that is more typical of mackerel teeth.
