Forest frogs cannot stay in water all the time, mainly based on their physiological characteristics and living habits. The following is a detailed answer to this question: 1. Physiological characteristics of forest frogs
1. Breathing method: Tadpole stage: breathing through gills. At this time, they are like fish and cannot live without water for a moment. Without water, they will die. During the juvenile and adult stages of frogs, their gills have degenerated and they use lung respiration. At this point, they must leave the water surface and live on land to meet their demand for oxygen. If they are forced to stay in water, especially when a large amount of oxygen is needed (such as in early autumn when the ambient temperature is around 8 degrees), they may die due to the inability to breathe.
2. Skin respiration: Although forest frogs can breathe through their skin while hibernating in water, it does not mean they can stay in the water all the time. During hibernation, their metabolic rate is extremely low, and their demand for oxygen is correspondingly reduced. 2、 The living habits of forest frogs
1. Habitat: Forest frogs live in mountainous areas with good forest vegetation and water sources, as well as in mountain streams and lush forests with surrounding plants. Breeding and overwintering in water, but mainly terrestrial during the adult stage, living in forests, shrubs, or grasslands.
2. Activity habits: Forest frogs often disperse and lurk alone under rocks, tree roots, and water plants in shallow flowing water or pond water. At night, they will move in shallow water, searching for new and suitable hibernation sites, but they will not move ashore.
3. Hibernation mode: Forest frogs have two ways of hibernating. One is to hibernate directly on land, requiring covering with dry grass, debris, etc. to keep the soil moist; Another way is to overwinter in water, where they gather in underwater burrows, do not eat or move, and rely on skin respiration to meet their oxygen consumption needs. 3、 The reason why forest frogs cannot stay in the water all the time
1. Respiratory restriction: Adult forest frogs use lung respiration and need to regularly come to the water surface for ventilation. If left in water for a long time, especially in high-density conditions, the bottom forest frogs may not be able to emerge from the water surface for breathing, leading to suffocation and death.
2. Living habits: The living habits of forest frogs determine that they need to alternate between living on land and in water. On land, they can forage, reproduce, and avoid natural enemies; In water, they can overwinter and reproduce. If it stays in the water all the time, it will go against its living habits.
Forest frogs cannot live in water all the time. They need to alternate between living on land and in water to meet their physiological characteristics and living habits.
