Section Research Notes

Data on the predator-prey relationship of small animal species is still understudied, especially in countries where scientific research is not yet widely shared, such as the Democratic People's Republic of Korea. Here, I report the interaction between a Hydaticus sp. larvae and a Dryophytes japonicus treefrog tadpole, where the invertebrate preyed on the vertebrate. This is the first data available on the diet of a Hydaticus sp. larvae, and the first behavioural observation of D. japonicus, in the Democratic People's Republic of Korea.
