quasipaa spinosa living habits
Quasipaa spinosa lives in luxuriant mountains and streams at an altitude of 600-1500 meters, especially in the mountains, streams, ditches and pools in the deep mountains and old forests. Likes to live in groups and forage at night, and is photophobic and afraid of being disturbed. The jumping ability is very strong, and the jump height can reach 1 meter. During the day, they mostly hide in stone caves or soil caves, and climb out of the caves in the evening to forage in the rocks on both sides of the mountain stream or in the bushes and grasses on the hillsides. will kill each other. The activity range is not large, mostly 20-30 meters around the cave, and when it is late at night, return to the cave. Thoracic frogs are very sensitive to changes in air and water temperature. On hot, dry, low-pressure nights, or just before a storm, they burrow out to jump to higher rocks or hillsides with a low, majestic chirping. When the water temperature exceeds 30 ℃, the frog will go into aestivation. After the frost in the late autumn, the water temperature is lower than 15 ℃, and it begins to hibernate. Before and after the sting, the water temperature rises above 15 ℃ successively.
quasipaa spinosa rearing
The gestational amount of the spiny frog is 300-2800; the breeding season is May-September. Spiny frogs mate before spawning; usually at night, with cuddly pairing habits, in vitro fertilization. Eggs are laid in batches, 122-350 eggs are laid each time, and 1000-1500 eggs can be laid in one breeding season; the eggs take 20 days to hatch in the water temperature of 16-18°C, and about 7 days in the water of 26-28°C The tadpoles hatched early can complete the metamorphosis in the same year after 4-5 months of growth; the tadpoles hatched in the middle and late stages need to overwinter and complete the metamorphosis in May-June of the following year; It takes about 2 years to reach sexual maturity.
