Misgurnus amamianus
Cypriniformes / Family: Cobitidae
- Total length
- 70-130 mm
- Range
- Amami-Oshima, Kikai-jima, Tokunoshima, Okinoerabu-jima, and (Iriomote Island)*The population on Iriomote Island is likely introduced by humans. The details of its native range remain uncertain.
Loaches are known to have an auxiliary form of breathing called intestinal respiration, in addition to gill breathing. In the diorama, bubbles can be seen emerging from its vent.
It is an endemic species of the Nansei Islands, newly described as a species in 2022. Although it closely resembles the pond loach (M. anguillicaudatus), it can be clearly distinguished genetically.
It prefers shallow wetlands with lush vegetation. It is thought to have once been plentiful in rice paddies, but it now faces the risk of extinction due to the loss of these habitats. In Tokunoshima, it was once commonly seen and even consumed as food. Being omnivorous, it uses its whisker-like mustache to feed on organic matter in the bottom sediments.

Habitat of This Animal:
B:Forest along the mountain ridge - B1:Forest near the settlement
Most of the forests in Tokunoshima Island are secondary forests that were once cleared in the past. Especially near the settlements, there are forests that have become well-lit thanks to recent pruning. Remains of paths, charcoal kilns, and fields form a reminder of the relationship between people and nature. Such forests accessible from settlements are inhabited by many living creatures fond of the well-lit environment.
