Most birds -- and all birds that fly -- have semi-hollow bones. Most reptiles, however, do not.
No, technically we all have hollow bones. Bones, while the host of the bones is alive, even in birds, have soft stuff in them that rots away once the host is dead.
Birds are the only things that have feathers and hollow bones.
All birds have feathers and birds are the only animals that do!
Animals like insects, have exoskeletons-basically they have no bones, and only have tough,protective, often shell like skin. Animals like cats, dogs, horses, giraffes and and birds are all endoskeletons- they have bones, and those bones are internal (on the inside of the skin).
Yes, animals with a back bone are vertebrates. The only animal I can think of that has bones but doesn't have a back bone would be a sand dollar. See if anyone here can think of any others.
Practically all except for whales and dolphins, and marine birds if you count those as sea animals. Only mammals and birds are endothermic.
