Quck answer
Frogs are amphibians that are found all over the world, except for Antarctica. They have smooth, slimy skin, long hind legs, and webbed feet. Frogs are known for their unique ability to jump great distances, but they also have several other interesting features. Frogs have three eyelids, a specialized tongue that can shoot out to catch insects, and a vocal sac that allows them to create loud calls. They also have a unique respiratory system that allows them to breathe through their skin while underwater. Overall, frogs are fascinating creatures that have adapted to survive in a variety of habitats.

Frog Skeletons vs. Human Skeletons

As known to those who have dissected a frog in biology class, the internal organs of a frog resemble those of a larger animal. Similar to mammals, including humans, a frog’s body comprises a heart, lungs, stomach, pancreas, liver, gallbladder, and intestines.
Despite the difference in external appearance, a frog’s skeleton bears resemblance to a human skeleton, particularly in the limbs. The bones of a frog’s front legs, such as the humerus, radius, and ulna, are similar to those in a human arm. However, in a frog, the radius and ulna are fused into one bone. Similarly, the femur supports a frog’s upper leg, while the tibia and fibula are fused in the lower leg bones. A frog’s shoulder blades and collarbones, known as scapulae and clavicles, respectively, are shaped similarly to those in a human body.
A frog’s digits, or fingers and toes, are composed of a group of small bones. Typically, a frog has four toes on its front legs and five toes on its back legs. The length and structure of these toes play a significant role in how frogs move. For instance, tree frogs have lengthy, flexible toes that allow them to climb and grasp stems and branches. Aquatic frogs have webbed feet that act as flippers to swim in water. Some frogs burrow into the soil and have shorter, wider feet that resemble shovels or spades.
However, a frog’s skeletal system differs from that of humans beyond the extremities. Unlike humans, frogs do not have necks, so they cannot move their heads up, down, or sideways. Additionally, frogs lack ribs; the rib-like structures visible in the picture above are part of their spine. A frog’s pelvis can glide along its spine, possibly assisting in jumping. The lower vertebrae of a frog’s spine are fused into a single bone called the urostyle.

Sticky Feet
Some frogs secrete a sticky or wet substance on their feet to climb trees and cling to surfaces. In some species, this substance is a thin layer of watery fluid that increases the friction between the frog’s feet and the surface. Other frogs have textured feet with a surface that acts like microscopic canals to keep the adhesive flexible and prevent it from cracking when the frog moves.
FAQ
1. What is the anatomy of a frog?
A frog has a unique body structure that is designed for its amphibious life. It has a long, sticky tongue that is attached to the front of its mouth and is used to catch prey. Its skin is smooth and slimy, which helps to keep it moist and protect it from predators. Frogs have strong hind legs that are used for jumping and swimming. They also have webbed feet that allow them to move quickly through water.
2. How do frogs breathe?
Frogs have lungs that they use to breathe air, but they can also absorb oxygen through their skin. This is why it is important for frogs to keep their skin moist. When they are underwater, they breathe through their skin. When they are on land, they use their lungs.
3. What do frogs eat?
Frogs are carnivorous and eat a variety of insects, spiders, and small animals. They use their long, sticky tongue to catch their prey. Some larger species of frogs will even eat small birds and mice.
4. How do frogs reproduce?
Frogs reproduce by laying eggs in water. The male frog will fertilize the eggs as they are laid. The eggs will then hatch into tadpoles, which will eventually grow legs and become adult frogs.
5. How do frogs communicate?
Frogs use a variety of vocalizations to communicate. They can make croaking, chirping, and whistling sounds. These sounds are used to attract mates and to warn other frogs of danger.
6. How do frogs protect themselves from predators?
Frogs have a few different ways of protecting themselves from predators. They can change color to blend into their surroundings, they can puff themselves up to appear larger, and some species of frogs secrete toxins from their skin that are poisonous to predators.
7. How long do frogs live?
Frogs can live anywhere from a few years to over 20 years, depending on the species. Some of the larger species of frogs tend to live longer than the smaller species.
8. Where do frogs live?
Frogs can be found all over the world, except for Antarctica. They prefer to live near water sources, such as ponds, lakes, and rivers. Some species of frogs are also adapted to living in deserts and forests.
9. How do frogs hibernate?
During the winter months, some species of frogs will hibernate. They will find a place to burrow underground or hide in a crevice. They will slow down their metabolism and breathing and will not eat or drink until they wake up in the spring.
10. How are frogs important to the ecosystem?
Frogs are an important part of the ecosystem. They help to control the insect population by eating large amounts of insects. They are also a food source for many predators. Additionally, some species of frogs are used for medical research and have contributed to the development of new medicines.
