bigcatkingdom said: hi, do you happen to know what condition it is that white tigers have? I used to think it was leucism but they still retain the black of their stripes so I realized that wasn't correct

I have heard a lot of things myself, but upon digging deeper into it a while ago this is what I know.

First of all they are often Bengal tiger/Siberian tiger hybrids (making them serve no conservation purpose), and they are all fairly inbred. 

Aside from the politics of white tigers, let’s get to the science (that I’ve simplified a bit). There is a pigment gene called SLC45A2, which modern Europeans as well as other animals like horses and chickens share. White tigers have a variant of this gene that inhibits the production of red and yellow pigments without affecting black pigments. Both parents must carry this recessive gene for the offspring to be a white tiger. So, in the way that some white horses and chickens aren’t Leucistic neither are these striped white tigers.

Another variation can cause there to be no stripes, resulting in so called “snowflake” or “ghost” tigers, but that includes a whole different set of genetics.

Interesting Zebra pattern variation. Are the strange markings the result of a healed wound, or something that this creature has had since birth?

“I took this photo of a goose at a city park in Southern Illinois. I had a hard time telling if his beak was dislocated because of an injury, or if It was that way since birth. If you increase the size of the photo you can see where the bottom beak is actually split in two parts.”
Hard to see, but the eyes are very red and the nose, paw pads, etc are very pink.

Geese beaks are toothed, but to be fair they aren’t really “teeth” as we define them.
What you’re seeing is rows of sharp points inside the beak which is called the tomia.
