A skin is the look of a snake during gameplay. There are 53 different default skins in Slither.io a snake can be; 23 of which are unimplemented.
You can gain access to all skins if you share on Facebook/Twitter, but you can simply click them, and go back to the page without logging in, and then choose your skin.
Please note that you cannot automatically pick a skin until you share, and if you do not share, you will automatically get one of the default skins. If you have SlitherPlus.io, you will unlock many other skins where the original Slither.io doesn't have.
