I think it is great that people are learning not to be afraid of snakes if they are harmless. But, just the other day here on Padre Island a small 4 year old child was bitten twice by a rattlesnake in the sand dunes and was in intensive care at Driscoll Children's Hospital in Corpus Christi. He did fully recover but required surgery on both legs.
I normally kill about 3-5 rattlesnakes in the spring and summer here at the house along with Coral snakes which seem to never go away. The good part about the coral snake is that I have time to get a hoe without fear of him striking which he can't do. When I lived on a wooded lot in southwest Houston I killed several coral snakes in the back yard.
I am not questioning, as a veterinarian, that you know a whole lot more than I do but water moccasions, rattlesnakes and coral snakes are just part of our habitat in south Texas. We grew up with the poisonous snakes also here at the farm.
I live in NW Houston. I have been trying to find someone who could identify a black snake about as big around as a #2 pencil, about 8" long with red bands. I did not see any other color on it. I was afraid it was a coral snake but could not remember seeing any yellow on it.
It was in my fish pond. I do not know if coral snakes swim or not. I have several very small 10 for $1 gold fish in there along with a one gold fish about 4" long. By the time I got back to check on him again he was gone.
Any information anyone could give me would be appreciated.
