Growth habits of stone frog

Stone frogs often live near clear puddles in Yinshan or near waterfalls with stone caves. They like to live under damp, quiet, light, near water and cool rock walls. At ordinary times, frogs often lie at the mouth of the cave or put their head out of the water to breathe and look for food. In case of disturbance, they quickly dive into the cave or under the rock, under the stone wall or in the water. Stone frogs have the habit of living in groups and foraging at night, and often several stone frogs or dozens of them live in one place together. In a quiet and suitable environment, they also go out to look for food during the day, and the night is the peak period of activity. Good at jumping and climbing, usually the activity is weak and stable, in the peak period of reproduction, frequent activities, with singing and dragging behavior.

Food habits of stone frog

Stone frogs like to eat active animals and do not eat dead or motionless food. in the natural state, they like to eat live baits such as earthworms, maggots, grasshoppers, ants, Loach, river crab, mole cricket and so on. Taste receptors are well developed and play an important role in their feeding behavior. sensory cells on the retina are particularly sensitive to moving objects, living animals are their feeding objects, and they are not sensitive to dead objects, and there is no feeding behavior. Feed on tender green aquatic algae or soft and delicate animals and plants during tadpoles. Artificial feeding can be fed with bait such as egg yolk, tofu, barley, rice, silkworm pupa powder, etc. The feeding time of stone frog is affected by the climate and environment. Under natural conditions, its feeding activity period is from March to November. After the Qingming Festival of the lunar calendar, a few frogs come out of the cave and feed. The temperature is suitable from April to June, the temperature is too high from July to August, and the feeding activity decreases. They often live in caves during the day, feed one after another in the evening, and the temperature changes from high to low from September to October. Feeding activities are decreasing day by day after November, and when the external temperature drops below 10 degrees Celsius, it stops feeding and goes into hibernation.

Hibernating habits of stone frog

Stone frog cold-blooded animals have no ability to regulate body temperature and heat preservation, and their body temperature changes with the change of external temperature. generally speaking, the suitable growth temperature of stone frog is 19-26 ℃. Spring and autumn are the seasons with the most frequent activity, the largest food intake and the fastest growth. April-June and August-September are the best periods for reproduction. When the water temperature exceeds 30 ℃, the skin water evaporation is large, which makes it feel uncomfortable. Feeding activity decreased, and when the water temperature dropped to 10 ℃, the metabolism was very weak and went into hibernation. During hibernation, the eyes are closed, do not eat and do not move, rely on the fat body to maintain life activities, and do not respond to external stimuli. If the water temperature rises to a suitable temperature during the hibernation period, it will come out again, often for about 4 months. After hibernation, there will be moderate weight loss.

The developmental process of stone frog

Stone frogs generally begin to estrus in April. Male frogs cry constantly attract female frogs to come and hug each other. Male frogs embrace female frogs' armpits with forelimbs with marriage tumors, and their chest and abdomen are close to the ventral side of female frogs. The male frogs begin to ovulate after hugging them. At the same time, female frogs are stimulated to ovulate 1000-3000 eggs each time, and eggs and sperm meet in water for in vitro fertilization. Sperm and eggs form a pile of eggs after fertilization. Eggs are often laid in gentle and shallow water, attached to rocks and aquatic plants, and the glial membrane outside the eggs is thick and sticky, sometimes connected into a cord or grape string, about 20 cm long, and the egg is generally 4 mm in diameter, up to 5 mm in maximum. Frog eggs usually hatch into tadpoles in 8-20 days. Tadpoles like to live in large rock crevices or gravel piles in stream pits. In a suitable environment, frogs generally become young frogs after 60-75 days of growth.
