Beings

Beings are one of the two types of the souls in the Universe as Aevilon (the difference between Beings and Entities is that Beings are born with one form where as Entities are born with more than one). 
​​Beings are further broken down into Vertabrates (a being distinguished by the possesion of a back bone or spinal column) or Invertabrates (a being lacking a backbone). Although, i will not change you knowledge on invertabrates as your knowledge is accurate, your knowledge of how Vertabrates are categorised is inaccurate. You may believe there are five different categories; Fish, Amphibians, Reptiles, Birds and Mammals, but there are really six. Humans are not mammals and actually belong to the sixth category, Humanoids- also known as Facile Loqueris, translating roughly as speak easy.
The reason that Humanoids are categorised differently to mammals is their ability to uses complex sounds and they are the only category with an open vocal system. The major difference is communication used by Humanoids which contains symbols and signals where as other Beings are only able to use symbols.
