How does a branch grow inside the tree?

I was splitting firewood, and to my surprise I found where it looks like there was a branch growing inside the trunk of the tree? How does something like this happen?

Hi, ever since I got this fish I've been wondering what species it is. I came up with two possibilities, either a comet goldfish or a white koi. However, as I'm not an expert in fish, I don't know how to determine this.

Black walnut tree

Hello. Thank you for considering my question. I have a pecan tree planted too close to a black walnut tree. They were planted at the same time, obviously too close together, but the black walnut has blocked the west sun and covered the little pecan tree from overhead, too. If I cut down the black walnut tree do you think the pecan tree would start to grow and mature? I have tried transplanting the little pecan tree, but it would not come out. It is still alive, but just does not grow. I hate to cut down the beautiful black walnut tree unless there if a very good chance the pecan tree will start to flourish.

Large bodies of unknown organisms in trees

For the last couple of years I’ve been trying to figure out what the strange invaders in the trees are. There are small black and white snake like critters which seem to be present in the larger bodies as well. The larger are black bodies and can be cow size or bigger. They move through the trees in an amoeba like fashion. There’s also the tube like creatures that slide down the branches while eating on the tree. They have a skeleton that’s net like and they look like giant caterpillars. What on earth is going on?

Flea eggs inhuman skin

I, unfortunately, have a flea problem and they seem to like me! It’s likely caused by my three dogs and cat finding them in the yard. Actually, the carpeted rooms in this rental is believed to have been infested with dormant fleas everywhere! I don’t get bites anymore although a couple years ago. I was covered in bites. NOW, I think fleas might be burrowing but more than that, I think there are eggs and even occasional larvae under my skin Is this possible?

Deer damage

I have a Bloodgood Japanese maple that is about 7 feet tall newly planted. I noticed yesterday that deer have been rubbing their antlers on it, which has stripped some of the bark off. I have encased the damaged areas in 4”plastic drainage pipe, which should protect it moving forward, but is there anything I can do to treat the damaged part of the bark? I don’t think there is any girdling, but the scraping is heavy on one or two branches.
