Endangered
Ryukyu tube-nosed bat
Murina ryukyuana
Ryukyu tube-nosed bat is a bat in the family Vespertilionidae (order Chiroptera) — Murina ryukyuana, recorded as Endangered and tied to Japan.
Appearance
It has straight hair in shades of brown, with dorsal hairs longer than its ventral hairs.
Murina ryukyana has rounded ears that are 35.5 to 37 mm (1.40 to 1.46 in) with tragi that are 9.5 to 10.5 mm (0.37 to 0.41 in).
Range and habitat
The bat is found only in the subtropical evergreen broad-leaf forests of Okinawa Island, Tokunoshima, and Amami-Ōshima. It is endemic to three islands of the central Ryukyus (Okinawa, Tokunoshima, and Amami-Ōshima) and is listed as Endangered by both the IUCN and Japan's Ministry of the Environment.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Although its diet has not been analyzed, morphology and very faint, steep frequency-modulated echolocation calls (peak ≈ 60 kHz) suggest prey capture by gleaning or short-range hawking inside clutter. Social calls have been recorded far more often than feeding buzzes, indicating a possibly important communicative repertoire and either greater reliance on listening for prey or very soft feeding buzzes.
In crisis
Forest loss is the primary threat. Understory foliage removal may reduce the roosting habitat of this species or harm roosting individuals.
