Is something that has a backbone.Your welcome.
No, anacondas are not mammals: they're reptiles. All snakes are reptiles. The word "reptile" means an animal that belongs to the taxonomic class Reptilia; "mammals" belong to the taxonomic class Mammalia. One big difference between reptiles and mammals is that mammals have mammary glands (and breasts, and the ability to produce milk), and they give birth to live animals, while reptiles lay eggs instead and produce no milk (although reptile venom is sometimes called "milk," it isn't truly milk). Something mammals and reptiles have in common is that they're both vertebrates, which means they belong to the taxonomic subphylum Vertebrata -- this means they both have backbones and spinal columns (unlike, for example, insects).
There are three subphylums in Chordata. Two of them are invertebrates - Urochordata (tunicates) and Cephalachordata (lancelets), while the third is Vertebrata (vertebrates). This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body. In the tunicates, the adult form no longer has the notochord. Another characteristic they share is that, at some stage during their lives, they have pharyngeal grooves and pouches that develop into other essential parts of their anatomy (many textbooks still state that all vertebrate embryos have gill slits, but there has been a great deal of development in the science of embryology to refute this claim). Chordates all have a post-anal tail, which means an extension of the notochord and nerve chord behind the anus, although this feature is no longer present in the mature forms of some creatures such as frogs, and some mammals such as people. Chordates also have a closed circulatory system, although not all Chordates have an actual heart like the vertebrate Chordates do.
The class of Vertebrata that includes the fishes.
Frogs are in the subphylum vertebrata.
The subphylum of a mammoth is Vertebrata, which includes animals with a backbone or spinal column. Mammoths are a type of proboscidean, belonging to the order Proboscidea within the subphylum Vertebrata.
