Unused textures/Hidden in transparency
Some of the textures have pixels set to 0 opacity, which makes them appear transparent when viewed with most image viewers. However, the color information of these pixels is still present and can be retrieved by disabling the alpha channel. Most of these textures are probably leftovers from the creation of the texture, that the editing program didn't erase but instead simply set the opacity to 0. Textures listed here had their alpha channel disabled to reveal unused/hidden pixels in the texture. Most of the invisible pixels are from development of the texture or already existing texture has been used as a template during development.
Hidden item texture changes

There are many hidden pixels from these atlas. The first one is that some Items has the old and new textures of items:
-A lot items are mixed with Pre-1.3 and 1.3 textures, which the 1.3 textures made a lot items centered properly. Another one is from the heads, which were changed in 12w36a to center it.
-Some are from snapshots/dev versions.
Entities
-
Arrow texture was used as a template for the leash knot. -
All shield textures have hidden banner texture. -
Chainmail armor was used as a template for the stray's robe. -
Bell appears to have some extra faces.
Mobs
There are hidden pixels in these mobs. As of 1.19.2, all mobs (except Ocelots) still have them.
Alex
In 1.8, Alex was added to the game. Invisible pixels include Alex's face with glasses, a reference to Jeb, a Mojang developer, as well as an unfinished arm texture similar to Steve's used texture.
Silverfish
The silverfish was added in Beta 1.8, but the texture was added in Beta 1.7. Invisible pixels consist of a few different colored regions around the "hair" textures.
Endermite
The snapshot texture of the endermite is seen underneath the new one.
Bat

An unused face texture can be seen and the spider head texture is seen under the wing. The spider texture was used as a template for the bat.

The ocelot and the cat variants were added in 1.2.1. The ocelot's hidden pixels contain an extra head texture, and all the cat textures feature an orange texture with black lines across it. After the 1.14, the ocelot texture no longer contains hidden pixels. Most of the new cat textures are edited from the old ones, as indicated by the similar hidden patterns. The textures also appear to have been cropped, since a large part of the old hidden texture is missing, with the exception of the red cat texture, which appears to be unchanged.
Wolf
The wolf was added in Java Edition Beta 1.4. All four wolf texture files feature similar hidden textures base on the cow, which suggests that the cow was used as a template for wolf textures. The most extreme is the collar texture, which originally contains only the collar, but there is an entire wolf and other unused textures hidden in transparency.
Blaze

The blaze has a hidden body texture.
Magma cube
A second pair of eyes are visible.
Wither
The wither's armor texture was based on creeper's charged armor. In the wither textures, there is a copy of the main head under the smaller one. The light blue color is visible without removing transparency.
Guardians
It seems that a template texture was used for designing the guardians.
Vex
