What are the differences between a frog and a human?
Numerous differences can be seen between frog blood and human blood. Perhaps the most obvious is the oval shape of the frog erythrocytes rather than the biconcave discs of human blood. Moreover, the frog erythrocytes have a nucleus (here stained blue) whilst human erythrocytes do not. There is less difference in size between the erythrocytes and leucocytes than in human blood. There are no platelets in frog blood.
There are lots of similarities in human and frog skeletal system, but still there are differences between both of them. First, the frog and human both have skull, but frog doesn't have neck that;s why they can't turn, lift, or turn their head like people can. Second, frog doesn't have ribs. the rib like bone you can see in their back is just a part of its spine.
