LOL..I find it amusing when I see people write things like "I am not afraid of any reptile" or "I am not afraid of anything". I am willing to bet a year's salary that if anyone of you encountered a full grown Croc in the wild...that decided to come after you..and that "you" were going to be its next meal...that sure as sh** you people would be SCARED!!!. It's a natural human emotion..so its okay..you can admit when your scared.
That doesn't constitute a phobia. That's like saying someone is affraid of cars if they get scared to see one speeding directly at them.
