Fun Ryukyu Flying Fox Facts For Kids

The Ryukyu flying fox (Pteropus dasymallus) is a megabat and fruit bat species that gets its name from its native habitat, the Ryukyu Archipelago in Japan. It is also found in the Philippines and in Thailand.

It is a bat that does not depend on echolocation, but rather uses its sense of smell and vision to get around and find food.

This fruit bat also has large fox-like eyes, hence its name. It is one of the fruit bats that depends on a variety of fruits and leaves for its diet.

It has a liking for figs and also eats insects sometimes. It is known for roosting during the daytime with others of its species and feeds during the night.

Females of the species give birth to a singular young one. As bats, they carry viruses that may be transmitted when humans come in close contact with them, but they are not aggressive towards humans.

Ryukyu flying fox fruit bats inadvertently disperse the seeds of important plants and hence are essential pollinators, even though they are not ideal for orchards.

Habitat loss and hunting for food have resulted in this species coming under threat and being given a Vulnerable status by the International Union for Conservation of Nature (IUCN). Sadly, a number of these bats tend to get entangled in nets meant to protect a fruit plant or crops.
