Presuming that is the monster( girl)'s tail and it is from Monster Hunter, that shape does narrow it down a fair bit. Most monsters in Monster Hunter tend to have some manner of wide part on the end of the tail, rather than just having it taper, and those without tend not to have horizontal spikes like the ones seen here. Given how they seem to extend along most of the visible length all the way to the tip, the only monsters that really come close are the Magala family (though without colour or more being visible which one can't really be identified). Lao-Shan Lung's tail would be the closest follow up, but it has a bit more of a long spike at the tip than this seems to have.
If instead this is based on Palworld or Helldivers 2, then I have no idea.
