Carcharhinus

So that's a big problem for the enforcement of CITES.

How are you going to know whether the permit you're looking for, I don't know, I'm going to say Carcharhinus limbatus or the black-tipped shark.

How do you know it's not another species with a tip at the end of the fin? If it's Leodon or Carcharhinus amblyricoides or is, you know, a different shark or Carcharinid, it gets complicated very quick.

So that's where genetics really helps us.

The other problem that we have internationally and where genetics is undeniably the best tool is that now that a lot of the countries can visually identify many things, The traders or the traffickers are removing all visual cues from the fin.
