The bullfrog generally reaches between 3.6 and 6 inches in length from snout to vent. The species is native to the United States and Canada, but has been widely introduced across the rest of the Americas, Europe, and Asia, and is regarded as an invasive one in some areas. Males are known to be aggressive and territorial, especially during breeding season (albeit being smaller on average than females), and have a distinct call reminiscent of the roar of a bull- hence its common name. It inhabits large, permanent bodies of water including swamps, ponds, and lakes, and can usually be found along the water’s edge. Its upper lip is often bright green, and males boast striking yellow throats. This frog has an olive green back, sides blotched with brown markings, and a whitish belly with grey and/or yellow spots.

The American bullfrog, often known simply as the bullfrog in Canada and the United States, is a species of amphibian in the Ranidae family (true frogs). Broadly, the endoskeleton is divided into two parts: 1. Some frogs change color between night and day, which is caused by light and moisture that stimulate the pigment cells and force them to expand or contract.BULLFROG SKELETON - RANA CATESBEIANA THE SCIENCE: Other frogs use camouflage to mix with dead leaves, lichens, and other environmental elements. Some frogs, such as the poison dart frog, are highly toxic. Special characteristicsĪll frogs have venom glands on their skin. Adult frogs roam the ground hopping with their strong hind legs. These feet contain a tibiofibula (shinbone), thigh, and astragalus and calcaneus (similar to the bones of a human ankle and heel). However, the frog has hind legs designed specifically for jumping. They are slim and of little use for jumping. The front legs of a frog are similar to those of humans. For a frog to have both aquatic and terrestrial habits, they require various internal parts of their anatomy. This means that their original method of movement is by hopping, jumping, or jumping. When a frog is underwater, oxygen is passed through the nostrils (which force the throat to swell out), and then compressing the floor of the mouth, which forces the air into the lungs. Amphibian skin is moisturized close to the skin. BreathingĪ feature of amphibians is the flexibility of their respiratory systems. The abdomen always contains both oxygen-rich blood and oxygen-poor blood. Like humans, frogs have a left and right atrium however, frogs have a single abdomen while humans have two. Trafficįrogs have three-chambered hearts. ![]() As in humans, the ear contains circular transitions that help control balance and orientation. Many parts of the frog’s brain correspond to those of humans. The frog has a highly developed nervous system consisting of a brain, spinal cord and nerves. Food then moves through the esophagus to the stomach. Instead, the frog uses its sticky tongue to catch food (such as flies or other insects). These teeth are very weak, and can not be used on agile prey or damage. Frogs have teeth along their upper jaw called upper jaw teeth, which are used to grind food before swallowing. The frog’s digestive system begins with the mouth. The word amphibian means “both sides of life,” derived from the Greek amphi, meaning of both, and living being, meaning of life. There are about 3,000 known species of modern amphibians, including Anura (frogs and toads), Urodela (newts and salamanders), and Gymnophiona (burrowing amphibians). ![]() Stationary – Handcrafts – Drawing Equipmentĭetailed frog skeleton model THE ANATOMY OF FROGS Generally.Microscope – Preparations (Environment).Packages of Compulsory Secondary Exercises.
