The weight of an amphibian's body is transferred to the limbs by using the pectoral and pelvic girdles.
because their limbs and bones are stronger than those of amphibians
Yes, amphibian skeletal structure includes joints for limbs and other body parts, just like we have.
Amphibians started out as tetrapods, fish like creatures that used limbs to move across the bottom of a marsh. In later fossils the limbs moved under the body so it could support itself. Later, it gained lungs so it could live outside of the water.
Hip bone transfer the weight of the upper body into the legs, by connecting spine to the lower limbs
The bones of the lower limbs are larger and heavier than the bones of the upper limbs because they must support the body's weight and provide stability during activities like walking, running, and jumping. The lower limbs also have larger muscle groups attached to them, which contribute to their increased size and strength compared to the upper limbs.
Pigs have longer and sturdier limbs compared to humans. Their limbs are adapted for supporting their body weight and rooting in the ground for food. Additionally, pigs have hooves instead of hands and feet like humans.
Amphibians have warm body temperature because they are cold blooded meaning they have to be in the sun a lot.
yes
yes
No, unlike smaller reptiles and amphibians, crocodilians do not have the ability to regenerate lost limbs. I would assume they rarely ever need to though, not many things are able to take on crocodiles, especially the Nile and Estuarine varieties.
Most amphibians have external fertilization, so outside the body.
