while others yellow, with green dorsal patterns. 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. Specific reasons behind such observations in color are currently unexplained, but mutations and maladaptations have been put forth by scientists as possible explanations. Further work must be conducted in order to elucidate the mechanisms behind these color changes. Habitat and distribution H. japonica are found in many parts of Asia, specifically in Japan, China, Korea, Mongolia, and Russia. H. japonica inhabits forest-like environments, bushlands, meadows, swamps, and river valleys. H. japonica, like most frog species, inhabit locations with both aquatic and terrestrial features. This is due to the necessity of the frog life cycle for both water and land. Changes in availability of native H. japonica habitats have resulted in rice paddies serving as lodging for H. japonica.H. japonica seems to be able to inhabit these rice paddies successfully and have a demonstrated preference for sites high in vegetation. Behavior The behavior of H. japonica when exposed to microgravity has been experimentally investigated. These frogs, under such microgravity conditions, would bend their neck backwards. These frogs would also walk backwards, an observation consistent with the behavior of sick frogs. The combination of neck backwards movement and backward walking could be indicators of motion sickness in the frogs. H. japonica were shown to adapt to the microgravity and were able to improve their jumping and perching activity over time. H. japonica, under micro-gravitational conditions, were also observed to attempt to eat but were unable to ingest the food. 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. Diet Hyla japonica forages in both breeding and non-breeding seasons. H. japonica are known to be opportunistic predators. This feature of H. 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 for that environment. A highest percentage of H. japonica’s diet is ants, followed by beetles and caterpillars. There does not appear to be a significant difference in the diet composition between the two sexes of H. japonica. However, during the breeding season, males have a higher chance of having an empty stomach due to the heightened energetic cost imposed
