![]() There does not appear to be a significant difference in the diet composition between the two sexes of H. japonica 's diet is ants, followed by beetles and caterpillars. japonica was discovered through analysis that showed a strong correlation between the relative abundance of organisms in a given environment and the prey composition H. japonica are known to be opportunistic predators. Hyla japonica forages in both breeding and non-breeding seasons. All the frogs that were sent to space were safely recovered and were observed to resume normal function after 2.5 hours back under normal gravity. japonica, under micro-gravitational conditions, were also observed to attempt to eat but were unable to ingest the food. japonica were shown to adapt to the microgravity and were able to improve their jumping and perching activity over time. The combination of neck backwards movement and backward walking could be indicators of motion sickness in the frogs. These frogs would also walk backwards, an observation consistent with the behavior of sick frogs. These frogs, under such microgravity conditions, would bend their neck backwards. japonica when exposed to microgravity has been experimentally investigated. ![]() ![]() japonica seems to be able to inhabit these rice paddies successfully and have a demonstrated preference for sites high in vegetation. japonica habitats have resulted in rice paddies serving as lodging for H. This is due to the necessity of the frog life cycle for both water and land. ![]() japonica, like most frog species, inhabit locations with both aquatic and terrestrial features. japonica inhabits forest-like environments, bushlands, meadows, swamps, and river valleys. japonica are found in many parts of Asia, specifically in Japan, China, Korea, Mongolia, and Russia. Further work must be conducted in order to elucidate the mechanisms behind these color changes. Specific reasons behind such observations in color are currently unexplained, but mutations and maladaptations have been put forth by scientists as possible explanations. Another frog found in Russia was observed to be fully blue, and was captured for observation, where it ultimately returned to a green/brown color. Frogs observed in South Korea were found to be entirely blue, while others yellow, with green dorsal patterns. japonica, on average, are larger in size compared to male H. japonica is also characterized by a dark spot on the upper lip below the eye. japonica is green/brown and the ventral body is white. They have an average skull width of 12.02☐.36 mm and an average skull length of 9.38☐.14 mm. japonica are on average 32.81☐.96 mm in length. The distance between nostril and upper lip (NL), distance between posterior corners of eyes (EPD), distance between semi-minor axis of the upper eye (LILe), angle between the two lines that connect the posterior corner of the eyes and ipsilateral nostrils (αEPD-N), and the angle between the two lines that connect the anterior corner of the eyes and the ipsilateral nostrils (αEAD-N) can all be used to differentiate between H. suweonensis is smaller and more slender than H. suweonensis is a closely related species to H. Studies have characterized the relationship between H. The binomial name, Dryophytes japonicus, is also sometimes used. Some authorities use the scientific name, Hyla japonica, in reference to the Japanese tree frog. There is an estimated 100 million of these frogs in Japan, but the accuracy is limited due to difficulty in counting. Their average litter size is around 340–1,500 eggs, and their lifespan is usually around six years. They are carnivores that prey on insects and spiders. They are generally located near vegetation near water sources and forests. The Japanese tree frog lives in a variety of habitats such as wetlands, forests, rivers, and mountains. Hyla japonica is synonymous with Dryophytes japonicus. japonica have been sent to space in a study that explored the effect of microgravity on H. japonica are not currently facing any notable risk of extinction and are classified by the IUCN as a species of "least concern". japonica is unique in its ability to withstand extreme cold, with some individuals showing cold resistance at temperatures as low as −30 ☌ for up to 120 days. Hyla japonica, commonly known as the Japanese tree frog, is a species of anuran native to Japan, China, and Korea.
