the snout does highly suggest Cuban in the OP and also in the example pics following, but i thought out of the lateral shots was a good sign of a Cuban as well...stress coloration was pretty indicative too, but that's mainly noticeable to people who have seen stressed Cubans before.
also note that the dorsal views show a pronounced difference in the Cuban gar snout shape, although this becomes less and less evident in larger specimens.
and Ricky, IMO the t-gar trident shows up in most juveniles to some extent, and generally fades away with age...of course we both know t-gars are highly variable in pattern, so some will retain the trident longer. other gar skulls show a bone pattern of the trident, but other species don't have it as clearly outlined as the tropicals.--
