for vertebratae the subdivision are: fishes, amphibian, reptiles, aves and mammals
invertebratae: mollusca, annalida, anthropoda, nemathoda and euphrodenata
What materials make up the endoskeletons of most vertebrates
Most animals are endangered because humans are moving into the areas where they live (by cutting down forests, or by mining, or farming, etc) and because there is less area for the animals to live in they die. Some other reasons are pollution poisons them, or overhunting kills them.
The mesentry is fold of peritonuem and inclosed tissue which conect intestine (jejunum n ileum) n their appendages with dorsal body wall of abdominal cavity.it is 15cm long and extend from duodonojejunal flexure just lateral(left) to midline and ends at sacro-iliac joint.

Shock absorbent between each vertebrae which keeps them separated when impacted by movement
Apart from the genus homo (humans) the types of primate locomotion are quadrupedalism (moving on all fours/with all four limbs), brachiation (swinging, branch running), and vertical clinging and leaping. "Arboreal quadrupedalism" is the most common type of locomotion among the primate order, meaning the use of grasping hands and feet with a long tail for balance. Although other primate walk on two limbs at times, humans are the only primates that actively engage in bipedalism (standing), the form of locomotion in which two limbs are used for moving.

Tails and legs help support a vertebrates body and allow it to move. Other structures to help a body move are muscle and bones.
Depends on the dinosaur. T. Rex had over 60 thick, conical, banana sized teeth that were up to 9 inches. They would grow back any teeth that they lost.
A scorpion is an Invertebrate that was actually a question my teacher asked me today.
There are many strange pets that you could own. For instance, a blobfish would be very strange to own. The same could go if you owned an eye-eye. A leatherback turtle isn't tha popular, either.
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.
invertebrates make up the majority:) Hope this helps:
btw: invertebrates make up 95% of the population. The 5% is vertebrates.
yes, that's what the name means. Non-vertebrates do not have a backbone
Biology major: The answer above is incorrect, Hagfish (Myxinoidea) are classified as vertebrates (controversial) because they are grouped with other agnathans, but do not possess vertebrae.
