The male toad lies on the body of the female toad and hugs the female toad tightly with its forelimbs. This phenomenon is called hugging, which means mating.

There is a brown-black swollen protrusion at the base of the thumb of the male toad's forelimb, called a nuptial tumor, which is used for hugging. Toad eggs are fertilized outside the body, and cuddling is the toad's behavior when laying eggs and ejaculating sperm.

When hugging each other, the cloaca (the total cavity at the opening of the digestive tract, ureter and reproductive ducts of the animal body) of the male and female toads are close to each other, which is conducive to the direct discharge of semen on the eggs, so that It will increase the fertilization rate of eggs.

Living habits:

It likes to hide in mud caves, under wet rocks, in grass, and beside ditches. The skin loses moisture easily, so it stays hidden during the day and comes out at night and dusk. Adult toads often spend the winter in colonies in underwater sediment or under moist soil on land.

Stop eating and use glycogen stored in the body to maintain the lowest metabolism. The hibernation will not end until the temperature rises to 10-20°C the following year. Predates and moves at night, feeding on beetles, moths, snails, fly larvae, etc. Breeding in captivity is easier than other frog species.
