* Vertebrate Tails: Most vertebrates have a tail made up of a series of bones called vertebrae. The scientific name for the tail bone is caudal vertebrae.
* Invertebrate Tails: Many invertebrates like insects have abdomens that are often called tails, but these aren't technically tails in the same way vertebrates have them.
* Specific Tails: Some animals have more specific tail terms. For example, the tail of a horse is called the dock, while the tail of a monkey is called the caudal appendage.
So, to give you a truly accurate scientific name, I need to know what specific animal you're asking about.
