A, family difference

1, frog: frogs for the animal kingdom, chordata, vertebrate subphylum, amphibian, anuran, new frogs suborder, forked-tongue frogs, tiger frogs genus amphibians.

2, toad: toad for the animal kingdom, chordata, vertebrate subphylum, amphibians, slipper subclass, anurans, toad family, toad amphibians.

Two, morphological differences

1, frogs: frogs flat head, slightly triangular, slightly pointed kiss end, mouth wide, transverse cleft, consisting of upper and lower jaw, male frogs in the corner of the mouth at the back of a light brown membrane folds for the sound sac, call drums into bubbles, short and wide trunk, the back end of the two legs, off the dorsal side of the hole for the cloacal cavity holes, the feet have four toes, the back foot five toes, and webbing. .

2, toads: toads have many bumps on the surface of the body, within the poisonous glands, body length of an average of 60 millimeters, the largest female up to 80 millimeters, the head is wider than the head length, the end of the muzzle is rounded, the muzzle prongs are significant, the cheeks are tilted to the outside, the nasal spacing is slightly less than the distance between the eyes, the eyelid is wide, slightly larger than the distance between the eyes, the tympanic membrane is significant, ellipsoidal, the male skin is rough, the head, the eyelid and the back of the head, the eyelid and the back of the densely covered with unequal warts, the female warts less, the head, the eyelid, and the back of the wart. Females with fewer wart grains, large and flat post-auricular glands.

Three, tadpole difference

1, frog: frog tadpoles are mostly more scattered, lighter in color, slightly rounded body, long tail, mouth long in the front of the head.

2. Toads: Toad tadpoles are usually densely packed in groups, with black bodies and lighter tails, oval bodies, short tails, and mouths on the ventral surface of the front of the head, and are smaller in size than frog tadpoles.

Frog

Frogs are slimmer and mostly good swimmers. The neck is inconspicuous and ribless. The ulna of the forelimb is fused to the radius, and the tibia of the hindlimb is fused to the fibula, so the claws cannot be turned flexibly, but the limbs are well-muscled. The most primitive frogs began to evolve early in the Triassic period.

The earliest present-day frogs with jumping movements appeared in the Jurassic. Because frogs feed mainly on insects and other invertebrates, they must live near water. There are about 130 species of frogs in China, and almost all of them are capable of destroying forest and farmland pests.

Toads

Toads are amphibious, and their skin is full of small holes that are permeable, plus they are not protected by structures such as amniotic membranes and shells from birth, which makes them more sensitive to the environment than other groups, and amphibians are considered to be the wind vane for detecting changes in the environment.
