gator vs croc I

[demjor19]

i would say the head/snout proportions and possibly the latteral line scale count could be two differences.

 

[E_americanus]

the snout issues are the main diagnostics...not as short or broad as a gators, more elongate with a moderately prominent second row of teeth in the upper jaw.

also, if you look carefully you can see traits of both shortnose and gators...the pattern is sort of a combination of the two fish, and the finnage tends to be somewhat similar to shortnose gar length, but with some of the striations of atractosteus gars.

i still have that specimen...albeit in a preserved state--
--solomon

lateral scale count? what's the diff?

thanks for popping up on this one.

okay thanks got that bit.

AH YES that nailed it. but to me only the dorsal fin seems much smaller.(frm the other pics) thanks, what was jordan saying about lateral scale count?

what happened to it? how big is he now?

that was just a suspicion...

 

[Polypterus]

Lateral line scale counts fall within normal for Gator or Shortnosed. The odd scale count with these fish is actually in the Pre-dorsal count on the few I've counted. This tends to be on the very High end or off the "scale" for a Gator and more in line with a Shortnosed.

These fish as adults also have a unique colouration that is a direct exaggeration of both Shortnosed and gator traits. It is one of the few fish where colour is a diagnostic trait.

To put the mention of colour in proper perspective...
