Which animals have endoskeleton and exoskeleton?

Tortoises have an adaptation called a shell which is modified into a rib cage, sternum. The shell is the outer layer which protects them from the predators. The shell acts as an exoskeleton for tortoises. So the tortoise contains both exoskeleton and endoskeleton.

How many bones does a frog skeleton have?

Are there bones in frog legs?

Just like in a person’s arms, in a frog’s front legs are bones called the humerus, the radius and the ulna. However, a frog’s radius and ulna are fused into one bone. The same is true for a frog’s legs — the femur supports its upper leg, and the bones of the lower leg, the tibia and fibula, are fused.

Why do frogs not have ribs?

When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in.

Why do frogs have backbones?
