Nope, those are definately shark teeth, and some of the best I've ever
seen drawn on an aircraft. I've collected enough fossils from Daniel
Island, SC to tell. Crocodilian teeth are conical in shape to
hold it's prey while the croc/gator drowns it. Most species of sharks'
teeth are flat (sometime faceted like the ones shown above) and
razor-like to slice thru their meals (I'm not including Whale Sharks
and Basking Sharks here since they feed like whales). As a result of
the different ways they feed, while a shark attack is the more
likely of the two, a gator attack is twice as likely to be fatal.
But Gino's still made a good point and it's one
I never thought of before - the front
end of the Apache does look like a gator; the PNVS kinda takes
the shape of a gator's nostrils now that I think of it.
It would
make a lot more sense to wear gator mouths on Apaches since they have quite a bit in common:
Alligators & AH-64:
Let's face it, they're both ugly. Dark
Gray/Green, bumpy finish to blend in with the surrounding terrain. No
need to have the most hydrodynamic/aerodynamic shape. Both are at the
top of the food chain in their native environments.
Sharks & Fighters:
Both have smooth, streamlined shapes and gray or blue/gray finishes.
Dark up top, light underneath. They both can move pretty fast and are
at the top of the food chains in their native environments.
Alligators & AH-64:
Can attack either on the move or from a "hover." While ungainly
looking, both can surprise you with a good sprint. Preferred tactic of
both is to attack from a "hover."
Sharks & Fighters:
Both have to constantly move forward to stay alive/in the air and the
preferred tactic of both is to attack from the prey's blind spot.
Crikey!
Now, as far as producing decals goes... well Jon knows who I'll suggest
