Native biota include invertebrates, fungi, bacteria and some vertebrates, notably bats. One hundred and thirteen species of bat have been recorded in Myanmar, including recently discovered endemics such as the Kachin Woolly Bat (Kerivoula kachinensis; Bates et al, 2004; Darwin Initiative, 2005, Francis, 2019). There is a single near- endemic bird, Greyish Limestone-babbler Turdinus crispifrons restricted to karst in Myanmar and neighboring Thailand. Most biota are well-adapted to light scarcity, including reduced eyes, pigmentation and wings, and specialised non- visual sensory organs (Keith et al., 2019). Beyond bats, no publications were found to further identify the characteristic biota of karst caves in Myanmar.
