A Yorkshire terrier belongs to the Animalia phylum.
No, on average, a human has more bones than a horse. An adult human has around 206 bones, while an adult horse typically has around 205 bones.
Vertebrates are characterized by having a backbone or spinal column made up of individual bones called vertebrae. They also have a well-developed brain enclosed in a skull, a closed circulatory system with a heart that pumps blood, and paired appendages such as limbs or fins. Vertebrates typically have a protective outer covering, whether it be fur, feathers, scales, or skin.
The bones specifically involved in the ankle joint are the tibia, fibula and talus. Any of the joints that unite the tarsal bones. (Tarsals)
The scientific name for cheekbones is zygomatic bones.
Birds have pneumatic bones.
pneumatic bones reduces the corporal density of animal faciliating flights
The pneumatic bones are where the air sacs, part of the respiratory system, connect with some of the longer bones. These bones are hollow to help with flight.
hollow bones belongs to chordata phylum
Nasal cavaties
Birds have some bones in their bodies that are "hollow." These are called pneumatic bones, and they help birds breathe when they are in flight. The bones of the pelvic girdle, some ribs, the humeru,s and the femur all are pneumatic.

Bone marrow is absent in birds, because they have pneumatic bones
Bones
Not really. It does have a hydro-skeleton where it uses pneumatic pressure to move along.
The only vertebrate phylum is Chordata. All animals with backbones, or any bones at all, are chordates. Tunicates, which are filter feeding invertebrates with a spinal nerve but no bones, are also chordates.
It's the same thing as a hollow bone. That's one of the characteristics birds posse than enables them to fly (if their bones had the same weight as ours, they wouldn't be able to lift). Some dinosaurs had the same type of bones. Hope it helped.
