Why do frogs croak in summer?
After mating, the female frog begins to ovulate in the water, with about 3000-6000 eggs at a time. At the same time, the male frog excretes sperm into the water. Sperm and egg cells combine in water to form fertilized eggs, which develop into tadpoles after 4-5 days of incubation.
Extended data
Frogs are omnivorous animals, among which plant food only accounts for about 7% of the diet; Animal food accounts for about 93% of the diet. From the dissected 60 frogs, it was found that among the animal foods, the animals that were swallowed involved 4 phyla, 4 classes, 10 orders and more than 30 families.
Frogs love to eat small insects and are good at finding moving small insects. When catching insects, their movements are as follows: a frog crouches in a small pit, with its hind legs curled up and kneeling on the ground, supported by its front legs, with its mouth open, its face up and its stomach bulging, waiting for something. A mosquito flew over and dangled in front of the frog. The frog jumped up with a jerk, turned his tongue and fell to the ground again. The mosquito disappeared, and it sat motionless, waiting for the arrival of the next prey.
