black tail

Question
I bought a new iguana from petco last week. He seems to be happy and healthy but this is new for me. So I was wondering if the black tip on his tail is normal?

Answer
Hi Kyle,
A black tip can be one of two things... if it is dry and brittle, then it is most likely dry gangrene and needs to be seen by a vet so the "dead" part of the tail can be removed to prevent it from moving on up the tail.  If it is soft and rubbery, then it is fine and is new growth  from an injury.  You might want to do a search for pictures of  both conditions so you can get a better idea as to what it is.
