Normally in nature no creature has more than one tail. Not so in fiction.
Any creature at all can have more than one tail, often to establish its other-worldliness. Sometimes the tails look like they might come from different creatures entirely. Usually such a creature is some form of supernatural or semi-divine spirit being, elemental, Kaiju, or demon.
The tail might split partway along into two or more tips, or there might be more than one complete tail springing directly from the base of the spine.
Compare Asian Fox Spirit and Bakeneko and Nekomata, most instances of which will fall under this trope. Doesn't have anything to do with twintails. Compare and contrast Multiple Head Case for the other end of the animal.
Examples:

- Realistic Pokémon: Subverted with Vulpix and Ninetales, as their extra "tails" are actually massive dreads of matted fur, and these only appear in wild specimens; in domestic Ninetales, daily brushing transforms the dreads into a six-foot train of fur that resembles an opulent gown.

The multi-headed one was actually the least dangerous, because all its heads prevented it from going through the hedge, but the multi-tailed one passed through without issue (an allegory for the Holy Roman Empire having many armies each led by their princes, and the Ottoman Empire having only a single leader).
- "Scraps", the Frankenstein's Monster of a Big Friendly Dog created by Igor in Carpe Jugulum.

The Orochi is a giant serpent with eight (or possibly infinite) heads and sometimes the same number of tails, and the Raiju, or Thunderbeast, is depicted as various animals, sometimes described with multiple tails. One particularly powerful nekomata is described as having seven tails rather than two, a result of its great age.

- Two-tailed scorpions are rare but not unheard of, most famously a double tailed bark scorpion that went viral on Instagram, nicknamed "Cardio" due to its two tails forming a heart shape. Sadly, Cardio died at an early age, due to complications with molting due to the unusual deformity, which is why the condition is rarely seen despite its seemingly more effective appearance, with each tail able to move independently.
- Though usually born with only one tail, lizards that have the ability to regenerate their tails can end up growing more tails than they had to begin with after the original tail is broken off. This could be because the old tail was not completely severed and regrows with the new tails or if the lizard had suffered enough damage to stimulate multiple points along the tail where regeneration normally takes place, causing multiple tails to grow. Just

examples

- For an example of an animal that always has more than one "tail", there's the marine polychaete worm Syllis ramosa
. Each individual worm has a body that splits into multiple branches known as stolons. These can detach and travel to the surface of the ocean, where they release eggs and sperm. Its relatives Ramisyllis multicaudata and the amusingly-named Ramisyllis kingghidorahi are even more extremely-branched, able to have a hundred branches or more.
- Slit-faced bats
have tails that split at the end into a "T" shape, with both ends being attached to the body by a membrane. The fork at the end of the tail is made up of cartilage rather than bone.

◊ have 2 cerci, while mayflies
◊ have 2 cerci and one median caudal filament.
