cell membrane
One animal that has thick feathers is the ostrich. Ostriches have a double layer of feathers, with the outer layer being long, loose, and soft, while the inner layer is shorter and denser, providing insulation and protection.
An external covering is a covering that is on the outside of an object. This could be anything from skin on humans to hard coverings like those on amoebas, fur on animals like bats, and scales on reptiles.
Sloths are found in the jungle, they are probably the slowest
It's called an "exoskeleton," exo meaning "outside." Humans and many other mammals, avians, reptiles and amphibians have "endoskeletons," endo meaning "inside."
It has always been a debate. Mesenchymal musculature in the middle tissue layer of ctenophores has invited speculation that they are triploblastic.

The part of an animal that forms a thin layer around the outside is the skin. Skin serves as a protective barrier, helps regulate temperature, and facilitates sensory perception. It also plays a crucial role in preventing water loss and protecting against pathogens. In many animals, the skin can be covered with fur, scales, or feathers, depending on the species.

An exoskeleton is a layer of skin that is like and "exo" (outside) "skeleton", that an animal sheds
The ectoderm is located on the outside layer of animal. It hold either the mesoglea or the mesoderm in.
Animal cells have a cell membrane, and plant cells have a cell wall, that performs that function. Edited answer: A plasma membrane in the plants and animal cells
The outside layer of a plasma membrane is made up of a double layer of phospholipid molecules. These molecules have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tail, creating a lipid bilayer that forms the structure of the membrane.

First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
