5. Mammals are amniotes.
6. Mammals breathe oxygen.
7. Mammals have three middle ear bones and a neocortex.
8. Mammals have internal reproduction.
Some of these characteristics are unique to mammals; others are found in some other vertebrates but not in all other vertebrates.
they all have a back bone
Backbone and an interior skeleton
There are actually five characteristics that all vertebrates have in common; a vertebral column composed of multiple vertebrea (spine), a cranium (the bone that envelopes the brain), a closed circulatory system, nural crest, and a pronounced cephalization.
which characteristic do all vertebrates have in common as embryos
Squirrels are vertebrates, they have spines.
Yes, Pythons are vertebrates as they have a backbone.
The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.
No, all tigers are vertebrates, as are all mammals. They have a vertebral column, a backbone, and an internal skeleton which are main characteristics of vertebrates.
Yes, skunks, like all mammals are vertebrates because they have backbones, one of the main characteristics of vertebrates
Yes. Anacondas, like all reptiles, are vertebrates. They have a backbone and an internal skeleton, which are the characteristics shared by vertebrates.
All vertebrates have a vertebral column (i.e a backbone). This is the main feature.
They are all vertebrates
